It’s often said the only constant in life is change. In the HVACR industry, that phrase has been especially true. We saw another year of transitions in 2024 that included evolving efficiency and refrigerant regulations, changing corporate net zero targets, the continued emergence of advanced heat pumps, and the impact of artificial intelligence (AI) in building management.  Smart and sustainable Throughout these transformations, the industry continues to overcome challenges and innovate as we transform the places where people live, work, and play into smarter, healthier, and more sustainable spaces.    As we look toward 2025, we can expect to see a continued, industrywide focus on decarbonization, heat pump development, A2L refrigerants, and AI as regulations expand and new technologies emerge.    Decarbonization  Decarbonization continues to be a very high priority for both the residential and commercial sectors Decarbonization continues to be a very high priority for both the residential and commercial sectors. This focus has transformed the way we design and install HVAC equipment and has created tremendous opportunities for those who invest in educating themselves on the evolving technologies, regulations, and incentives. Today’s building professionals and homeowners have an unprecedented number of incentives available at the federal, state, and utility levels encouraging decarbonization transitions.  Digital and net zero services For example, tax credits such as 25C for consumers and 179D for commercial building owners were expanded under the Inflation Reduction Act (IRA) and can significantly reduce the upfront costs of high-efficiency equipment, creating a compelling offer to replace less efficient systems. In commercial buildings, combining high-efficiency HVAC equipment like electric heat pumps with digital technologies and net zero services can help empower organizations to optimize their buildings and subsystems for both the short- and long-term. Heat pumps  Heat pump technology has advanced significantly in recent years, providing an electrified, high-efficiency HVAC option for nearly all applications – even those operating within colder climates. The Department of Energy’s (DOE) Residential Cold Climate Heat Pump (CCHP) Technology Challenge has propelled the successful introduction of heat pump prototypes that can withstand subfreezing weather. Similarly, the DOE’s Commercial Building Rooftop Heat Pump Accelerator program has helped drive packaged heat pump performance toward greater efficiency for commercial and light commercial buildings located in colder climate zones.  Water-to-water heat pumps Water-to-water heat pumps can replace legacy chiller and boiler combinations without the need for major changes Innovations in commercial water-to-water compound centrifugal heat pumps are also accelerating decarbonization within building retrofits. For facilities that require simultaneous heating and cooling, such as hospitals and universities, water-to-water heat pumps can replace legacy chiller and boiler combinations without the need for major changes to the existing HVAC infrastructure. This partial decarbonization approach can help building operators achieve their decarbonization goals while also lowering operational expenses (OpEx). In many instances, this reduction in OpEx also provides a path to funding additional decarbonization strategies.      A2L refrigerants   The EPA continues to make strides in reducing the consumption and production of hydrofluorocarbons (HFCs) under the American Innovation and Manufacturing (AIM) Act. As part of the AIM Act, the Technology Transitions Program will usher in sector-based regulations beginning January 1, 2025, prohibiting the manufacturing of equipment using refrigerants with a GWP higher than 700.  New protocols As a result, new equipment will continue to hit the market throughout 2025. In tandem, many contractors and technicians will begin working with A2L refrigerants for the first time. Because these refrigerants are classified by ASHRAE as mildly flammable, new protocols for safe refrigerant servicing, storage, and transportation, and refrigerant leak detection (RDS) requirements will be necessary for some applications.   ACCA A2L refrigerant training Contractors should complete ACCA A2L refrigerant training and EPA section 608 certification With these changes, it is important to become familiar with updated codes, including UL 60335-2-40, 3rd and 4th editions, ASHRAE 15 and 15.,2, and the AHRI Safe Refrigerant Transition Task Force (SRTTF), as well as local and state regulations. Contractors should also complete ACCA A2L refrigerant training and EPA section 608 certification. Additionally, new digital tools such as RDS calculators can help contractors navigate A2L leak detection requirements and mitigation strategies while in the field.    AI and controls   AI is positioned to continue to make a huge impact in HVAC. We’re seeing more service techs using generative AI and co-pilots for troubleshooting rather than paging through manuals. At the same time, AI technology can predict if connected HVAC units may have issues, making it possible for service techs to address potential issues in their earliest stages or prevent them from happening altogether. Both of these use cases can help technicians service equipment more quickly, efficiently, and accurately, which can increase equipment longevity and reliability while reducing downtime and total cost of ownership.   Building performance AI-powered building controls can provide a holistic view into contextualized, full-building performance More HVAC systems are being equipped with AI-enhanced controls and reporting. The capabilities these tools provide can give building owners greater opportunities to optimize building performance, improve occupant comfort and well-being, and more easily reach sustainability targets. From a building management perspective, AI-powered building controls can provide a holistic view into contextualized, full-building performance, occupant experience, and sustainability. Openness and flexibility As AI becomes more commonplace, AI-centric building standards, such as ASHRAE Guideline 36, will also continue to emerge that balance sustainability with occupant comfort, health, and safety.    As we move into 2025, we can expect to see another year of equipment innovations, technology advancements, and evolving regulations. As an industry, we continue to face change with openness and flexibility. And it’s this mindset that empowers us to meet, and exceed, expectations – now and in the year to come.

As environmental regulations become increasingly stringent, the HVAC/R industry is turning to sustainable refrigerants to minimize environmental impact. A3 refrigerants—flammable gases with low global warming potential (GWP)—are emerging as a preferred choice. However, their adoption introduces additional regulatory requirements. EPA regulations To address these challenges, the industry is leveraging innovative solutions like enhanced small-diameter copper tubes, which enable compliance with EPA guidelines while maintaining performance and safety standards. In this article, we’ll explore key EPA regulations for A3 refrigerants and how small-diameter copper tubes play a vital role in optimizing system performance, ensuring safety, and achieving regulatory compliance.  Understanding A3 Refrigerants A3 refrigerants help HVAC/R systems align with current and upcoming environmental regulations A3 refrigerants are characterized by their low GWP and flammability, making them a sustainable alternative to traditional high-GWP refrigerants. Common examples include propane (R-290) and isobutane (R-600a). By reducing greenhouse gas emissions, A3 refrigerants help HVAC/R systems align with current and upcoming environmental regulations. Their benefits go beyond regulatory compliance. energy efficiency A3 refrigerants improve energy efficiency, enabling systems to operate more effectively while consuming less energy. This dual advantage of sustainability and operational efficiency reduces both carbon footprints and operating costs. As global regulations continue to phase out high-GWP refrigerants, A3 options stand out as a viable solution that balances environmental responsibility with system performance. Their efficiency and compliance capabilities position A3 refrigerants as a key player in the future of HVAC/R system design.  Advantages of Small-Diameter Copper Tubes 1. Meeting EPA Charge Limits  Small-diameter copper tubes offer a significant advantage in adhering to EPA refrigerant charge limits. With their reduced internal volume, these tubes require less refrigerant to maintain optimal performance. This feature is particularly beneficial when working with A3 refrigerants, as the EPA enforces strict charge limits to mitigate flammability risks while upholding efficiency.  2. Boosting System Efficiency with Enhanced Heat Transfer  When enhanced with internal grooves, small-diameter copper tubes maximize surface area contact with refrigerants Copper’s exceptional thermal conductivity, even with smaller tube diameters, ensures effective heat transfer. When enhanced with internal grooves, small-diameter copper tubes maximize surface area contact with refrigerants, further increasing heat transfer efficiency. This improvement translates to lower energy consumption and reduced operating costs, all while delivering reliable cooling performance.  3. Durability, Safety, and Ease of Installation  Using small-diameter copper tubes reduces the refrigerant charge required within a system, enhancing safety. Copper’s lightweight and flexible properties, especially when annealed, simplify installation, particularly in compact systems with complex configurations. Its natural corrosion resistance also ensures durability and long-term reliability, minimizing maintenance needs over the equipment’s lifespan.  Innovating for a Sustainable Future  As the HVAC/R industry transitions to A3 refrigerants, adapting to stricter EPA regulations requires innovative system designs that address safety, efficiency, and performance challenges. Small-diameter copper tubes provide a practical solution by reducing refrigerant charges, enhancing heat transfer, and delivering reliable, durable performance.  reducing environmental impact These copper innovations are especially valuable for compact, high-performance systems that demand precision and compliance with environmental standards. By embracing these advancements, the HVAC/R industry can ensure systems are future-ready, capable of meeting evolving regulations while maintaining efficiency and safety. Small-diameter copper tubes are paving the way for a more sustainable HVAC/R landscape, helping businesses succeed in reducing their environmental impact while achieving regulatory compliance. 

By now, the HVAC industry is well versed in, and operating successfully with, various HFC refrigerant production and consumption reduction schedules put forth by regulatory bodies. Under the EPA American Innovation and Manufacturing (AIM) Act, for example, the U.S. experienced a significant reduction (another 30%) in January 2024, advancing the goal of an 85% HFC phasedown from historic baseline levels by 2036. And the EU is working toward its stated objective of an HFC phaseout by 2050. technology transition rules In addition, technology transition rules are at work to limit the use of higher global warming potential (GWP) refrigerants in specific applications, ranging from commercial air conditioning to residential heat pumps. Consequently, with each passing year, the industry can expect HFC availability to feel increasingly “tighter.”  additional requirements Once the EPA’s proposed rules become final rules, more details will be available to guide the industry In addition, by the end of summer 2024, it’s expected that the U.S. EPA’s proposed rule, “Phasedown of Hydrofluorocarbons: Management of Certain Hydrofluorocarbons and Substitutes Under Subsection (h) of the American Innovation and Manufacturing Act of 2020” will be finalized—subjecting the HVACR industry to additional requirements. Once the EPA’s proposed rules become final rules, more details will be available to guide the industry on steps they need to take in terms of compliance.  takeaway from HFC phasedown The main takeaway from the progress of the HFC phasedown is that businesses at every level of the HVAC industry must employ a strong refrigerant management strategy. Several of the “Eight Rs” below represent best practices that many industry members already follow. By structuring your strategy around these measures, you can align your business with regulations and ensure you have the resources necessary to continue servicing equipment with legacy refrigerants as well as to successfully introduce A2L solutions to customers.  Eight Rs of Refrigerant Management  Regulations Whether you’re manufacturing, installing, or servicing equipment, keeping up to date with regulatory changes is key to compliance. In addition, because recent and pending regulatory changes may impact both legacy and new-generation refrigerants and equipment, understanding changes offers an important tool for planning for what’s next.  Recordkeeping Regulatory bodies conduct audits relying heavily on recordkeeping and reporting to ensure compliance Regulatory bodies conduct audits relying heavily on recordkeeping and reporting to ensure compliance. This will mainly impact manufacturers, importers, and equipment owners.  However, accurate and consistent recordkeeping on the contractor side can prove to be incredibly beneficial to your business’s operating efficiency, bring added value to your customers, and support sustainability objectives.  Repair leaks Practicing consistent, effective leak detection and repair is an important part of regulatory compliance that can also impact your bottom line by reducing service gas costs and keeping systems operating at peak efficiency. In addition, it’s the first line of defense in reducing HVAC systems’ impact on the environment.  Replace equipment As systems approach the end of their serviceable lifetime, define which new, higher-efficiency units utilizing A2L refrigerants offer the best replacements. Remind customers of benefits such as reduced energy consumption and operating costs.  Retrofits It may still make sense, where applicable, to perform a refrigerant conversion If equipment is in good condition and not nearing the end of its serviceable lifetime, it may still make sense, where applicable, to perform a refrigerant conversion. Thus allowing the equipment to operate with a more sustainable and readily available refrigerant.  Recovery The first step in supporting refrigerant circularity is recovery, which means removing refrigerant from a system and placing it into a separate container. During this process, it’s important to maintain the refrigerant’s value/purity as much as possible by not mixing gases.  Reuse/Recycle This means returning recovered refrigerant to the same system or another system with common ownership. Removing oil, moisture, or other contaminants via minor “cleanup” or filtering of the recovered gas may be part of the process.  Reclamation HFC phasedown and the transition to A2L refrigerants will continue to impact the operations of HVAC contractors Reprocessing recovered refrigerant to meet virgin purity specifications allows it to be reintroduced commercially for industry use and is becoming increasingly important in ensuring ample legacy refrigerant supply exists to meet current servicing needs. In the U.S., reclamation must be performed by EPA-certified reclaimers.  Whether it’s through new regulations or processes and requirements already underway, the HFC phasedown and the transition to A2L refrigerants will continue to impact the operations of HVAC contractors, equipment owners/operators, OEMs, equipment sellers/distributors, and others. A2L transition Implementing a solid refrigerant management strategy built around the Eight Rs can help you consistently and effectively stay updated on regulations, take steps to remain compliant, and contribute to industry efforts to mitigate global warming. In addition, following the Eight Rs can keep your company ahead of continued HFC phasedowns, aligned with the A2L transition, and in a strong position to both maintain your legacy refrigerant business and possibly expand your customer base through new-generation solutions.

SNAP Rule 26 marks an important milestone in the transition from commercial refrigeration to new refrigerants. The rule lists refrigerant substitutes that provide a spectrum of technological solutions to meet required performance, global warming potential (GWP), safety, and environmental standards.  SNAP stands for Significant New Alternatives Policy, a program by the U.S. EPA (Environmental Protection Agency) under the Clean Air Act. In general, the program aims to evaluate and regulate substitutes for ozone-depleting substances, considering their overall risks to both human health and the environment. Impact of SNAP Rule 26 Final SNAP Rule 26, Protection of Stratospheric Ozone, lists acceptable substitutes in commercial and industrial refrigeration. SNAP Rule 26 will be effective July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register as of July 15, 2024. The incorporation by reference of certain material listed in the rule is approved by the Director of the Federal Register “To date, the SNAP program has provided a very effective framework for evaluation and approval in support of innovation and the transition to new technology,” says Andrew Pansulla, Technical Service Engineer, The Chemours Company, a global chemistry company that provides a range of refrigerant products. We asked Pansulla to elaborate further on the impact of SNAP Rule 26 and what lies ahead. Q: How will the Rule’s finalization impact various commercial refrigeration sectors? Pansulla: The rule’s finalization will impact commercial refrigeration in several ways. Areas, where impact will likely be seen, include providing more acceptable refrigerant options, adherence to updated standards, new equipment design standards, and the exemption of propane from the venting prohibition for refrigerated food processing and dispensing equipment. These impacts could trigger changes in operational, manufacturing, and environmental compliance strategies in the commercial refrigeration sectors. SNAP Rule 26 will enable the adoption of the listed substitutes, including Chemours Opteon™ refrigerants, with global warming potential (GWP) lower than existing refrigerants. This rule does not require any changes to existing equipment and will impact only new equipment that uses the specific substances referenced in the SNAP rule. Q: What is the outlook for additional requirements for safe handling and use of alternative refrigerants? What specific safety standards are expected or appropriate? Pansulla: As part of the comparative risk framework used by the EPA to assess new alternatives, the EPA considers and implements use conditions that will ensure the safe use of products. These use conditions rely upon existing safety standards (e.g., UL and ASHRAE) which are available at the time the rule is finalized. In the case of SNAP Rule 26, many of the use conditions require adherence to UL 60335-2-89 and ASHRAE-15-2022. These standards are reviewed and updated periodically to maintain relevance with the products subject to the standards. Q: What are any limitations of the use of A2L refrigerants under SNAP Rule 26? Pansulla: There are two main categories of limitations under SNAP Rule 26. The first, as mentioned above, is the adherence to specific safety standards that apply to refrigerants that are designated as mildly flammable (A2L). The second is based on the GWP of the refrigerant. In the case of the A2L refrigerants subject to SNAP Rule 26, the EPA imposed conditions on the type of equipment and specific circumstances in which the substitute may be used. For example, the EPA is permitting the use of R-454A in supermarket systems, but only on the high side of a cascade system, or when the refrigerant charge capacity is less than 200 pounds. Q: Which new-generation A2L refrigerants are fit for which commercial refrigeration applications? Pansulla: Under SNAP Rule 26, the EPA deems R-1234yf, R-1234ze(E), R-454C, R-455A, R-457A, and R-516A as acceptable subject-to-use conditions for various commercial refrigeration applications. This selection is primarily driven by these refrigerants having GWPs under 150. However, certain applications necessitate refrigerants with higher GWPs due to unique performance characteristics. For example, R-454B and R-32 were listed for industrial process refrigeration with exiting fluid temperatures below minus 30 degree Celsius because these two specific refrigerants have lower boiling points than the other six less-than-150-GWP alternatives. However, it is critically important to consider the additional use conditions when designing equipment with refrigerants that have a GWP greater than 150. Q: So various equipment needs different refrigerants? Pansulla: The EPA purposefully lists several different refrigerants in each application to allow for equipment manufacturers to consider a variety of different factors that go into refrigerant selection, such as energy efficiency, capacity, normal boiling point, temperature glide, cost, safety, and use conditions. There is no one-size-fits-all solution for the entire commercial refrigeration industry. Q: How can commercial refrigeration businesses achieve a smooth transition to A2Ls? Pansulla: Keys to a smooth transition to A2Ls include understanding what refrigerants the EPA has approved as acceptable substitutes under the SNAP program, the sector-based GWP limits imposed by the Technology Transitions Program under the American Innovation and Manufacturing (AIM) Act, and which refrigerants provide the best combination of technical performance and environmental characteristics. Many resources are available to navigate the regulatory landscape and select the best low-GWP refrigerants to meet the needs of this industry. Working with companies like Chemours, who has nearly a century of refrigerant innovation and experience, is a great first step in the transition process. Q: What is the “staying power” of A2Ls — based on their chemistry, sustainability, and other attributes, combined with regulations such as SNAP Rule 26? Pansulla: The identification, selection, and development of new refrigerants that deliver required performance while meeting increasingly stringent environmental standards is a challenging process. With the identification of certain hydrofluoroolefin-based (HFO) refrigerants as an alternative to meet these criteria came a new safety classification. These HFO-based refrigerants are classified as A2Ls. While slightly more flammable than existing hydrofluorocarbon-base (HFC) refrigerants, HFOs are much less flammable than hydrocarbons, which are classified as A3 (two categories higher on the ASHRAE flammability spectrum). Moreover, such refrigerants offer an excellent alternative to substances with higher toxicity, such as R-717. The listing of A2L refrigerants in SNAP Rule 26 clearly indicates that such refrigerants can be used safely in commercial refrigeration as well as many other applications, which are subject to the SNAP Program, when adhering to the applicable safety standards.

The flammability of the new class of low-GWP refrigerants is a source of misunderstanding and unnecessary anxiety among contractors who will be working with the newer materials, which must be used by HVAC equipment manufactured beginning Jan. 1, 2025.   A2L refrigerants The newer A2L refrigerants, specifically R-454B, perform similarly to previously used materials such as R-410A, and flammability is so mild as to be almost negligible. What’s needed is more education to make contractors more comfortable with the newer refrigerants. And sensible precautions, of course.   flammability of refrigerants Among the trainers educating the industry on the benefits of, and needed precautions for, the new materials is Don Gillis, Technical Trainer of Chemours.   “The flammability part of it is the elephant in the room,” says Gillis. “Our training seeks to remove the fear of the unknown and to get ahead of what the expectations are.”  Don Gillis experience At Chemours, he is applying his real-world experience to address the practical aspects of the refrigerant transition Gillis’s background includes more than 32 years of experience in the industry, 24 of which were on a service truck. Before coming to Chemours, he was the Senior Technical Trainer for Copeland compressors where he helped to train thousands of contractors across North America.  At Chemours, he is applying his real-world experience to address the practical aspects of the refrigerant transition in hundreds of training sessions this year.   peculiarities and similarities of new refrigerants “Change is now coming so fast that technicians are struggling to keep up,” says Gillis. “We need more education, not just about the differences in the new refrigerants but also about the similarities. We need to understand the peculiarities and the similarities of new refrigerants compared to what we used in the past.”   Features of A2L refrigerants The refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world Working with A2L refrigerants such as Opteon XL41 (R-454B) is similar to working with R-410A. For R-454B systems, the installation and service procedures are similar. Moreover, the best practices that technicians have used for years remain applicable with A2Ls. These refrigerants are safe when handled properly, offer lower toxicity, and have been used effectively around the world to increase efficiency and reduce emissions.  When working with R-454B, processes that were once described as good practice will be required. These processes include purging a line with nitrogen to remove any residual refrigerant, testing lines under pressure for 60 minutes, and documenting the results.  training sessions Gillis is seeing higher-than-expected attendance at his training sessions this year, with actual attendance sometimes doubling what was expected. There are classes with more than 100 in attendance, even 200 and 300 in some cases. While most of the training is geared toward contractors, distributor training is similar, ensuring that the “counter people” speak the same language as their customers when it comes to the transition.   Urgency due to transition “We are not having an issue of people not coming to training,” says Gillis.  “I think right now there is a new urgency because [the transition] is happening. Dealers and distributors are telling them the new equipment is coming out, and they are peeking in to see what the hubbub is all about. We want everyone to get better. The more knowledge the better.”   R-454B refrigerant availability All equipment manufactured or imported beginning in 2025 will use newer refrigerants New equipment that uses R-454B refrigerant will be on the market within weeks. At least three original equipment manufacturers (OEMs) say they will have equipment out by the end of the first quarter. All equipment manufactured or imported beginning in 2025 will use newer refrigerants.  Misinformation Misinformation is a problem as the refrigerant transition looms, says Gillis. For example, 50 to 60% of attendees at a recent training session were still under the impression that the new refrigerants contain hydrocarbons such as propane. Not true. The flammability of A2L refrigerants more closely resembles the refrigerants currently in use than materials at the far end of the flammability spectrum.  Fact-checking and myth-busting A2L refrigerants have already been used safely for years in automobiles, window air conditioners, PTAC systems, and dehumidifiers.  “I’m all about fact-checking and myth-busting,” says Gillis. “You don’t know what you don’t know.” Some of the misunderstandings may have come from earlier messaging in the industry that addressed A2Ls along with other “flammable refrigerants” such as propane, thus confusing the matter.  Key points Key points Gillis seeks to communicate in his training sessions include:  ∙There are no hydrocarbons or propane in A2L refrigerants.  ∙Although similar to previous refrigerants, an A2L refrigerant cannot be used in an existing unit.   ∙No extra ventilation or placards are required for trucks carrying A2L refrigerants; tanks of Chemours’ Opteon XL41 (R-454B) refrigerant can be transported on their sides.   ∙The 440-pound maximum allowable refrigerant truck load stays in place.  ∙Safety and handling requirements and good installation and service practices are required.  ∙Factors such as servicing, installation, safety, pressure, temperatures, and oils are the same for R-454B as for R-410A.   To access educational resources, contractors and others may visit Opteon.com to request training by webinar, remotely, or in person. There are also YouTube videos available on demand.   training certificate Chemours provides a 2-hour certificate of attendance, with a number enabling “credit” with NATE, ACCA Although there is currently no EPA requirement for special training on the new refrigerants, the jury is out on whether a requirement might be forthcoming. There currently are also no federal or state certifications. Chemours provides a 2-hour certificate of attendance, with a number enabling “credit” with North American Technician Excellence (NATE), Air Conditioning Contractors of America (ACCA), or whomever.   high-GWP refrigerants The U.S. AIM Act will limit the amount of high-GWP refrigerants that can be made in coming years. As the manufacture of legacy refrigerants is phased out over time, existing legacy systems will need to use more reclaimed/recovered refrigerants from existing systems. Fortunately, the processes of reclamation are improving, and even refrigerant mixtures will still have value in the market moving forward. {##Poll1709537519 - What is your preferred format when it comes to training on new aspects of HVAC equipment and installation?##}

The idea of Energy as a Service involves shifting the traditional business model from selling energy as a commodity to providing a comprehensive package of goods and services to address a customer’s energy use and management. Rather than selling energy, the approach encompasses complete stewardship of a company’s energy needs in exchange for a monthly fee. Because 40% or so of a company’s typical energy needs are related to heating and cooling systems, implementing Energy as a Service (EaaS) is tied directly to a company’s HVAC systems. heat pumps and HVAC technologies In the EaaS scenario, an outside company pledges to meet a customer’s energy needs at a discount, say 5%, below what they currently pay. By then strategically seeking to lower the customer’s energy costs by more than 5%, the EaaS company uses the extra margin to pay its own costs and to attain a profit. For example, if a customer’s energy costs can be lowered by 30%, the EaaS company retains 25% every month for the term of the agreement, typically 10 years. Any costs associated with providing the service come out of the 25%. In the EaaS scenario, an outside company pledges to meet a customer’s energy needs at a discount Specifically, working to lower energy costs by that much involves an upfront investment in infrastructure, such as heat pumps and HVAC technologies, to lessen energy consumption. The idea is that the profitability of lowering energy costs will offset even a substantial investment over time. Energy-related infrastructure Briefly stated, that is the business model of Budderfly, which assumes management of a company’s energy infrastructure and becomes the “account holder” with the utility. Once an EaaS contract is signed, Budderfly then invests to upgrade the customer’s energy-related infrastructure, including LED lighting, refrigeration, etc., in addition to HVAC. The goal is to decrease energy usage by 30% or more.  Budderfly typically upgrades the variable frequency drive (VFD) When upgrading the infrastructure, Budderfly “owns” any new infrastructure assets for the term of the EaaS agreement, say 10 years, and amortizes the cost over the timespan. At the end of the term, the assets are turned back over to the customer unless they renew the contract. In the HVAC arena, Budderfly typically upgrades the variable frequency drive (VFD), economizers, and other equipment in a rooftop unit or other machinery when it takes on a new customer. Embraces the EaaS scenario EaaS has a direct incentive to invest in the newest technology to slip the client energy usage “Looking at the opportunity to save 5% of their energy costs, many customers think it seems too good to be true,” says Al Subbloie, President, CEO and Founder at Budderfly. The price of the EaaS contract is based on a two-year review of the customer’s utility bill, which creates a baseline against which the 5% discount is provided. On the consumption side, replacing a rooftop unit with a new Lennox, Carrier, or Trane high-efficiency unit can provide 30 to 40% savings in energy usage. When a customer embraces the EaaS scenario, the EaaS company has an immediate incentive to invest in the newest technology to lower the customer’s energy usage. The more they save on energy, the more they earn in profits. EaaS approach In contrast, in a business model involving energy purchased as a commodity, there is little urgency to upgrade the equipment. That explains why so much equipment currently installed is so out-of-date and energy inefficient, says Subbloie. “We did not expect the infrastructure to be so bad,” he says. “I am sharing something the world is not aware of. As long as cool and hot air are coming out of the vents, no one is looking at the energy impact.” In fact, the EaaS approach is a growing factor in decarbonization. “We are a private capital method to save the world,” says Subbloie. “We are aligning capitalism and putting it to use to save the world (from climate change),” he says. Additional investments by Budderfly Budderfly can make a profit on an EaaS contract if it can achieve 30% savings on total energy costs Subbloie says Budderfly can make a profit on an EaaS contract if it can achieve 30% savings on total energy costs. Of the 30%, Budderfly returns 5% typically to the customer and then spends about 15% on capital improvements, amortized over 10 years. Additional investments by Budderfly include 3 to 4% on technology such as thermostats, metering and controls, and data systems. Other costs are to pay Budderfly’s 300 or so employees.  In the refrigeration realm, which might account for 15 or 20% of energy usage, Budderfly deploys controllers (such as KE2 Therm Solutions and NRM) to smartly regulate the compressor operation in refrigeration units. Door alert monitors and upgraded seals avoid any leakage of cool air. Deploying R-290 (propane) refrigerant systems boosts energy efficiency. EaaS strategy When Budderfly deploys solar systems, the cost becomes just another line on the customer’s bill – there is no purchase agreement or lease involved. Budderfly is transparent with the customer in terms of the money they invest in infrastructure and other costs. In addition to providing the customer with the initial 5% discount, Budderfly also typically shares with the customer half of the proceeds of any energy savings they can achieve above 30%. The EaaS strategy is applicable to a variety of markets, but Budderfly is finding initial success in the quick-service restaurant (QSR) market, where repeatable footprints of individual locations make EaaS calculations predictable and scalable. Probably 80% of their business is in casual dining and QSR installations, including 75 or so well-known restaurant brands; they work with large franchisees who operate multiple brands. top-down relationships Budderfly also has firms in healthcare needs, nursing facilities, office buildings, amenity stores Budderfly is also working to establish “top-down” relationships at the restaurants’ corporate level, which has the ability to impose EaaS as a standard throughout its footprint. “As the climate focus becomes more important, a restaurant brand might say to do it everywhere,” says Subbloie. Hotels and motels are another vertical markets amenable to this approach, and Budderfly also has business in healthcare markets, nursing facilities, office buildings, convenience stores, and other retail. They seek to limit each building’s size to 200,000 square feet or less. Regulated and deregulated rates Budderfly has a team that handles the onboarding of new customers, which involves a short, two-page agreement. Their automated system is connected to 500 utilities, and Budderfly tracks all the regulated and deregulated rates. If rates go up, their billing increases, still based on the 5% reduction that is part of the agreement.  Budderfly benefits from its high-volume acquisition of HVAC equipment at lower prices. “We buy a lot of stuff, we have agreements to buy at volume pricing, and we are constantly negotiating to lower the price,” says Subbloie. “We buy the best of the best to achieve the greatest energy-saving outcome, for obvious reasons. We negotiate prices on the expectation that our volume will make it lucrative (for OEMs).” Subbloie says Budderfly is the largest buyer of roof-top units in the country. Energy-efficient HVAC systems Budderfly’s model enables the facility of the latest and most energy-efficient tools In the scenario of buying energy as a commodity, customers have less incentive to proactively replace their HVAC infrastructure with more efficient models. They also may not have the means to invest in capital improvements to achieve better energy efficiency outcomes. In contrast, Budderfly’s model encourages the installation of the latest and most energy-efficient equipment, and that the equipment is fine-tuned and maintained. By pushing the transition to decarbonization based on an old-fashioned business motive (i.e., profit), Budderfly seeks to jump-start the adoption of more energy-efficient HVAC systems on a large scale. “We have an economic model that is sustainable,” says Subbloie. Investment in AI Budderfly also provides customers with abundant data on their energy usage, including submetering architecture that does 20 to 40 measurements per location.  Each point of energy use reports back every five seconds, providing operational data and suggesting a possible investment in artificial intelligence (AI) to make operations even smarter.

Wren is a climate subscription service that helps individuals offset their carbon footprint through monthly contributions. Users can calculate their carbon emissions using Wren’s intuitive calculator and fund various climate projects, including refrigerant destruction. Wren emphasizes transparency by providing regular updates on the impact of contributions, including data, photos, and stories. The platform aims to make climate action simple and effective, ensuring that every dollar contributes to meaningful environmental change.  About A-Gas  A‑Gas is a world pioneer in the supply and lifecycle management of refrigerants and associated products and services. Through the first-class recovery, reclamation, and repurposing processes, we capture refrigerants and fire protection gases for future re-use or safe destruction, preventing harmful release into the atmosphere. For over 30 years, A-Gas has supported clients and partners on their environmental journey by supplying lower global warming gases and actively increasing the circularity of the industries we serve, building a sustainable future.   Challenge  HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 The widespread use of refrigerants like HCFC-22 (R22) presents a significant environmental challenge. HCFC-22 is a potent greenhouse gas with a global warming potential (GWP) much higher than CO2 (one molecule of R22 has a global warming impact 1,810 times that of one molecule of CO2). If not properly managed, its release would have a negative impact on the atmosphere. As these refrigerants reach the end of their lifecycle, there is an urgent need for effective solutions to prevent their emissions and minimize their environmental impact.   Solution  To address this challenge, A-Gas recovers refrigerants for reclamation or destruction at A-Gas facilities across the country. By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry through its on-site refrigerant recovery service (Rapid Recovery®), refrigerant buyback programs, and wholesale supplier reclaim program (Refri-Claim™). HCFC-22 destruction project The ACR methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017 Wren and A-Gas formed a partnership to provide Wren subscribers with the opportunity to fund an HCFC-22 destruction project through the generation of A-Gas carbon credits to ensure the gas does not escape into the atmosphere. While the ACR (formerly American Carbon Registry) methodology has included HCFC-22 as eligible for destruction-generated offsets since 2017, few have completed such projects because the price of HCFC-22 is so high; it is more profitable for organizations to reclaim this product.  ACR’s methodology As such, this is one of the first HCFC-22 destruction projects utilizing ACR’s methodology. Approved by the International Civil Aviation Organization (ICAO) to provide carbon credits in its Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA), ACR is highly regarded across the world.  Results  The partnership yielded multiple environmental benefits:   Emissions Avoided: The initiative successfully avoided the release of 16,000 tons of CO2-equivalent emissions by destroying HCFC-22. This substantial elimination of greenhouse gas emissions demonstrates the effectiveness of the program.   Subscriber Engagement: Wren provided its subscribers with detailed updates on the impact of their contributions. These updates included data on the quantities of HCFC-22 destroyed and the corresponding emissions reductions. This transparency helped build trust and encouraged ongoing participation in climate action.   Educational Impact: The collaboration raised awareness about the importance of proper lifecycle refrigerant management. Wren and A-Gas educated the public on lesser-known aspects of climate change mitigation by highlighting the environmental benefits of destroying high-GWP substances.   Conclusion  This partnership enabled an environmentally conscious solution for the used refrigerant By leveraging Wren's platform to mobilize individual contributions and A-Gas' technical expertise in lifecycle refrigerant management, this partnership enabled an environmentally conscious solution for the used refrigerant. It underscores the potential for innovative partnerships that can help to further reduce emissions in the refrigerant industry.  refrigerant destruction protocols and technology "We are excited to work with A-Gas to push forward the standard of refrigerant destruction protocols and technology," said Landon Brand, CEO, of Wren. Landon Brand adds, "This is one of the most reliable and impactful project types we have found in our years of funding climate solutions, and we hope our community can keep blazing a trail to eliminate these dangerous refrigerants."

Honeywell announced that Hisense, a global consumer electronics and appliance manufacturer, will incorporate Honeywell's energy-efficient Solstice low-global warming potential (GWP) refrigerant into its residential air conditioning units. Hisense units will use Honeywell Solstice® 454B, a low-GWP refrigerant acknowledged for its outstanding performance in both cooling and heating. Hisense’s decision to integrate Honeywell’s Solstice refrigerant is in line with global efforts to phase out higher GWP refrigerants for air conditioners and heat pumps. Technological advancements "Driven by a commitment to pioneering scientific and technological advancements, Hisense relentlessly strives to enhance the quality of life and bring boundless joy to countless families,” said Hao Wang, general manager of the Supply Chain Management Department at Hisense. “Our alliance with Honeywell signifies a formidable leap towards sustainability, as we integrate cutting-edge refrigerants into our industry-pioneering air conditioning units, ensuring unparalleled cooling efficacy with minimal environmental impact." Use of high-HFCs Integration of Honeywell’s Solstice refrigerant into Hisense units comes amidst the recent increase The integration of Honeywell’s Solstice refrigerant into Hisense units comes amidst the recent increase in legislative mandates across the country to reduce the use of high-GWP hydrofluorocarbons (HFCs) in response to the growing global emphasis on addressing climate change.  The partnership between Hisense and Honeywell also follows the U.S. Environmental Protection Agency’s recent announcement of a 40% quota cut in the production of HFC refrigerants as of January 1, 2024. Lower carbon footprints “The world is migrating away from refrigerants with high-global warming potential, but it is also accelerating innovation to create responsible replacements that lower carbon footprints and improve energy efficiency, all without sacrificing safety and end-product performance,” said Jeff Dormo, president of Honeywell Advanced Materials. “Honeywell anticipated the need for these solutions more than a decade ago when we introduced our Solstice technology, and today we are pleased to be able to partner with manufacturers like Hisense that are leveraging our expertise to enhance their own sustainability efforts in alignment with the global energy transition.” New capacity for its Solstice technology Honeywell has invested more than $1 billion in research, development and the creation of new capacity for its Solstice technology, which currently has applications in refrigerants, blowing agents, aerosols and solvents, and is also being evaluated for expanded use in metered dose inhalers. Since its introduction in 2011, the use of Honeywell Solstice technology has helped avoid the potential release of the equivalent of more than 326 million metric tons of carbon dioxide into the atmosphere or the carbon emissions from nearly 70 million gasoline-powered passenger vehicles per year.

Shadow Industrial, the UK’s pioneering shortwave infrared heating specialist, recently helped St. Helen’s Chapel, in Colchester, Essex, specify and install a low-carbon heating system, keeping the congregation warm and costs down. Installing 14 of its powerful ceiling-hung and wall-mounted heaters and 16 controllers from scratch, the new system has given visitors a warm, comfortable and sustainable place to worship, whatever the weather. Futureproofing sensitively Reducing energy consumption and increasing its efficiency is a goal that touches on every part of UK business and industry, especially against the backdrop of the drive towards Net Zero 2050. It’s especially important for the UK’s Eastern Orthodox Church, which has over 250 properties nationwide. With strict and ambitious ESG commitments, futureproofing these assets in the face of tighter climate change regulation, whilst delivering their core function is a real challenge. It’s especially important for the UK’s Eastern Orthodox Church, which has over 250 properties nationwide Some of its sites are centuries old, and it can be difficult to upgrade facilities here. One particular area of concern is how to heat these large, high-ceilinged, and poorly insulated structures. Crucially, visitors need to be comfortable, but simultaneously ensure utility bills and waste are kept to a bare minimum. Warming-up the congregation It was an issue at the forefront of the church’s mind when they took over the lease of St Helen’s Chapel, Colchester, Essex in September 2020; especially as the 16th Century, Grade-II building had no existing HVAC system. The congregation bore the brunt of this unfortunate situation over three consecutive winters, where temperatures would sometimes plummet down to 1°C. It made the church a particularly uncomfortable place to worship.  Grade-II building had no existing HVAC system Initial use of oil-fired heaters proved futile, failing to provide the necessary levels of warmth and releasing a large amount of CO2. Next, industrial fan heaters were introduced, to little effect; noisy, they also proved a significant disruption to services. Following further research, they decided to trial shortwave infrared heating, approaching Shadow Industrial on the recommendation of their electrician, who had installed its solutions on previous projects. A heating revelation Shortwave infrared heating is one of the fastest-growing and most disruptive categories of heating Shortwave infrared heating is one of the fastest-growing and disruptive categories in the heating and ventilation sector. Simply, the technology works by emitting focused radiant heat through a precision-engineered smooth parabola reflector; it heats the person, not the air around them. Wall-mounted and directed downward at individuals, the energy creates a comfortable and instant warmth, mimicking the gentle heat of the sun. It’s fast becoming popular in historic ecclesiastical buildings as it’s easy to install, with limited impact on the structural fabric, in addition to its effective heating function and low energy consumption. It is also unaffected by changes in air movement, making it particularly efficacious in drafty settings such as those found in heritage sites, like St. Helen’s Chapel.  Unrivalled performance, at a reasonable price Installed in 2023, Shadow Industrial’s systems have significantly improved the comfort of congregants, allowing them to remove coats during services. The impact was particularly felt among older people and children, for whom extreme cold can have an adverse impact on health during extended services. The client was worried their tight budget would not be enough to fully equip the church’s interiors Initially, the client was worried their tight budget would not be enough to fully equip the church’s interiors with heaters. However, it proved far cheaper than traditional electric or gas central heating. The entire system and installation totaled £20,000. Putting this in context, they were initially quoted £100,000 for underfloor heating; this represents a massive 80% upfront saving, with greater performance–a no-brainer decision. The entire system and installation totaled £20,000. Shadow Industrial and its team Commenting on the project, Shadow Industrial’s founder, Steve Levy, says, “We are deeply committed to the preservation and longevity of heritage buildings. With a focus on comfort, we have successfully executed numerous heating projects with this in mind, of which St. Helen’s Chapel is the latest. It’s such an important local landmark and it was great to be able to provide a solution that benefits all those who work, volunteer, and pray here.” Father Mark Shillaker added, “Shadow Industrial’s infrared heating systems have had a transformative effect. Now visitors can worship in maximum comfort even on the chilliest winter mornings. In fact, since we’ve installed these heaters we’ve actually seen an uptick in service attendance. Many thanks to Shadow Industrial and its team for their expertise and ongoing support.” Church of England's Heat Decarbonization Plan Shadow Industrial’s electric heating systems, present a low-carbon, net-zero alternative ideal for heritage structures, churches, and culturally significant buildings. They even align with The Church of England's Heat Decarbonization Plan, offering compliance and sustainability in a non-intrusive way.

When a company is one of the largest beverage distributors in the U.S., it’s crucial to stay ahead of the curve on everything that drives customer satisfaction, corporate responsibility, and a strong bottom line. Hensley Beverage Company did exactly that when it collaborated with Chemours and American Refrigeration Supplies, Inc. (ARS) to implement a system utilizing a new-generation A2L refrigerant, Chemours Opteon™ XL20 (R-454C).  Completed in 2023, the installation paves the way for companies throughout the commercial refrigeration industry to embrace refrigerant technologies that are both cost-effective and environmentally sustainable. Situation  Hensley Beverage, a Phoenix-based beverage wholesaler, supports a customer base of more than 9,000 accounts and more than 2,500 individual products, operating out of six locations across Arizona, USA. Hensley remains committed to maintaining exceptional product integrity, upholding its business legacy The company recently completed an acquisition that expanded its distribution footprint into New Mexico, making it one of the nation's largest family-owned and operated beverage distributors. As it grows, Hensley remains committed to maintaining exceptional product integrity, upholding its multi-generational family business legacy, and supporting various environmental objectives.  Upgrading refrigeration systems These factors, coupled with the current regulatory landscape (notably, the phasedown of legacy hydrofluorocarbon (HFC) refrigerants), have put Hensley’s focus on ways to upgrade its refrigeration systems. For the past several years, Chemours, ARS, and Hensley have worked together to retrofit the distributor’s existing R-22 and R-404A systems to Opteon™ XP40 (R-449A), a hydrofluoroolefin (HFO) blend offering zero ozone depletion potential (ODP) and a significantly lower global warming potential (GWP) than legacy products. Phasedown of HFC refrigerants Hensley Beverage is proud to partner with Chemours, TBSI, and ARS to help develop innovative solutions" However, with the ongoing phasedown of HFC refrigerants under the U.S. EPA’s American Innovation and Manufacturing Act (AIM), the teams began weighing the benefits of an even bolder upgrade.  “Hensley Beverage is proud to partner with Chemours, TBSI, and ARS to help develop innovative solutions and responsible business practices that drive sustainability in our community," said Alex Dunn, SVP of Operations, Hensley Beverage. Partnership and collaboration Alex Dunn adds, "These groundbreaking results are a culmination of partnership and collaboration. It is refreshing to work with three organizations that are this passionate about developing pioneering products that will help shape a better future for the communities we serve.” Solution  A mildly flammable refrigerant with an ASHRAE A2L safety classification, Opteon™ XL20 is designed for use in new equipment Even as Chemours, ARS, and Hensley continued to employ retrofit solutions in some areas strategically, they explored options that would put the company in a stronger position for the long term. Chemours recommended bringing Opteon™ XL20 (R-454C) into Hensley’s refrigeration plan. A mildly flammable refrigerant with an ASHRAE A2L safety classification, Opteon™ XL20 is designed for use in new equipment, so Hensley identified an old R-22 system near the end of its life that was ideal for replacement by a new system using Opteon™.  Opteon™ XL20 Opteon™ XL20 has been used for several years in Europe and is expected to become the new norm in the U.S. by 2026, based on the current direction provided by the EPA. Leveraging its experience in Europe, the Chemours team of technical service and business development resources is prepared to support end users as they consider trial installations using A2L refrigerants.  Opteon™ XL20 - The future of sustainable low- and medium-temperature refrigeration: GWP of 148 (a 96% reduction versus R-404A). Zero ODP. Enables much higher charge sizes than highly flammable A3 refrigerants. Is a close performance match to R-22 and R-404A. Offers the optimum balance of performance and environmental sustainability. Provides an easy, cost-effective alternative to legacy refrigerants and new equipment applications. Utilizes well-known technology for ease of service and maintenance. performance, efficiency, and sustainability “Hensley was an early adopter of Opteon™ XP40, retrofitting equipment to experience better environmental outcomes, as well as high performance in low- and medium-temperature applications. Experiencing these benefits of HFOs whet their appetite to ask, ‘What next?’," said Joe Martinko, President of Thermal and Specialized Solutions, Chemours. Joe Martinko adds, "With a strong dedication to supporting their communities and the environment, while operating an efficient and thriving business, Hensley is a company that pushes the envelope. Chemours was ready with our next-generationOpteon™ XL20, which will ensure they achieve maximum performance, operating efficiency, and sustainability." servicing and Installation Heatcraft and Copeland had the knowledge and experience of emerging A2L requirements The installation brought together additional resources from the HVACR industry, including Copeland and Heatcraft Refrigeration Products, two ARS manufacturing partners as well as Technical Building Services, Inc. (TBSI), the local HVAC service provider. As global HVACR technology pioneers helping customers achieve their sustainability, decarbonization, and regulatory compliance goals, Heatcraft and Copeland had the knowledge and experience of emerging A2L requirements and the capabilities to support the project. TBSI was selected as the contractor for installation and servicing. Time- and cost-efficient With the team assembled, Chemours took the head on the project, ensuring that the contractor, Hensley’s service personnel, and others involved were certified through the ESCO Institute’s A2L refrigerant training program, and answering any questions from the local authorities.  After safely recovering the R-22 for use in other Hensley systems, the team from TBSI started removing the existing Keg 6 equipment, hanging new evaporator coils, and running new refrigerant lines. Installation, evacuation, and charging procedures were very similar to the current refrigerants in use by industry, making for a time- and cost-efficient process. Climate technology Copeland has always been focused on not just setting the standard in climate solutions" “Copeland has always been focused on not just setting the standard in climate solutions with pioneering brands in compression, controls, software, and monitoring, but pioneering the evolution in this space. Our role in the system design and installation for Hensley was right in our wheelhouse," said Brian Schroeder, Engineering Manager, Refrigerants, Copeland. Brian Schroeder adds, "What we accomplished together demonstrates that by bringing together energy-efficient products,regulation-ready solutions, and expertise, we can revolutionize the next generation of climate technology for the better.” R-454C refrigerant “Our tools and gauges were already enabled for the R-454C refrigerant. The startup and charging of both systems went pretty smoothly," said Sergio Pelayo, Vice President of TBSI. Sergio Pelayo adds, "TBSI is proud to have participated in the project at Hensley and, by doing so, added to the variety of equipment we’ve worked on since founding our business in 1990. This was a great opportunity to grow our experience with A2Ls.” Copeland monitoring data  Copeland applied monitoring units to the systems that capture nearly two dozen data points every second To make sure the system performed as expected, Copeland applied monitoring units to the systems that capture nearly two dozen data points every second. The data has shown that the systems are running as designed. “We are thrilled with the results of the R-454C project with Hensley Beverage," said Bob Landi, Vice President and General Manager of Heatcraft Refrigeration Products. Bob Landi adds, "As we continue our journey toward new regulation compliance, this successful collaboration has been instrumental in leveraging Heatcraft’s new product design efforts, with A2L refrigerants being an important part of the mix. We are poised to head the industry and provide more customers like Hensley with cutting-edge solutions that drive their success.” Summary Influenced by upcoming regulatory changes and stronger organizational ESG commitments, the commercial refrigeration industry’s transition to lower GWP refrigerants is inevitable. Opteon™ refrigerants provide organizations with lower GWP options that can help extend the useful life of their systems, as well as new equipment options that enable decades of reliable operation. Moreover, these systems answer the consumer preference for businesses that utilize responsibly manufactured products and support a greener environment.  Hensley’s approach Hensley’s approach demonstrates an ideal way for companies to meet the needs of refrigerating their products while following the guidelines of the HFC phasedown. It’s important to assess where equipment is in its lifecycle and determine if it makes the most sense in terms of budget, performance needs, and corporate vision to 1) retrofit existing equipment for more efficient and sustainable operation or 2) replace it with A2L refrigerant technologies and products. 

When they are one of the largest beverage distributors in the U.S., it’s crucial to stay ahead of the curve on everything that drives customer satisfaction, corporate responsibility, and a strong bottom line. Hensley Beverage Company did exactly that when it collaborated with Chemours and American Refrigeration Supplies, Inc. (ARS) to implement a system utilizing a new-generation A2L refrigerant, Chemours Opteon™ XL20 (R-454C). Completed in 2023, the installation paves the way for companies throughout the commercial refrigeration industry to embrace refrigerant technologies that are both cost-effective and environmentally sustainable. Situation The company recently ended an acquisition that grew its distribution footprint into New Mexico Hensley Beverage, a Phoenix-based beverage wholesaler, supports a customer base of more than 9,000 accounts and more than 2,500 individual products, operating out of six locations across Arizona.  The company recently completed an acquisition that expanded its distribution footprint into New Mexico, making it one of the largest family-owned and operated beverage distributors in the nation. As it grows, Hensley remains committed to maintaining exceptional product integrity, upholding its multi-generational family business legacy, and supporting a variety of environmental objectives. These factors, coupled with the current regulatory landscape (notably, the phasedown of legacy hydrofluorocarbon (HFC) refrigerants), have put Hensley’s focus on ways to upgrade its refrigeration systems. Phasedown of HFC refrigerants For the past several years, Chemours, ARS, and Hensley have worked together to retrofit the distributor’s existing R-22 and R-404A systems to Opteon™ XP40 (R-449A), a hydrofluoroolefin (HFO) blend offering zero ozone depletion potential (ODP) and a significantly lower global warming potential (GWP) than legacy products. However, with the ongoing phasedown of HFC refrigerants under the U.S. EPA’s American Innovation and Manufacturing Act (AIM), the teams began weighing the benefits of an even bolder upgrade. “Hensley Beverage is proud to partner with Chemours, TBSI, and ARS to help develop innovative solutions and responsible business practices that drive sustainability in our community. These groundbreaking results are a culmination of partnership and collaboration. It is refreshing to work with three organizations that are this passionate about developing pioneering products that will help shape a better future for the communities we serve,” Alex Dunn SVP of Operations, Hensley Beverage.  Solution Chemours recommended bringing Opteon™ XL20 (R-454C) into Hensley’s refrigeration plan Even as Chemours, ARS, and Hensley continued to strategically employ retrofit solutions in some areas, they explored options that would put the company in a stronger position for the long term. Chemours recommended bringing Opteon™ XL20 (R-454C) into Hensley’s refrigeration plan. A mildly flammable refrigerant with an ASHRAE A2L safety classification, Opteon™ XL20 is designed for use in new equipment, so Hensley identified an old R-22 system near the end of its life that was ideal for replacement by a new system using Opteon™.  Opteon™ XL20 has been used for several years in Europe and is expected to become the new norm in the U.S. by 2026, based on the current direction provided by the EPA. Leveraging its experience in Europe, the Chemours team of technical service and business development resources is prepared to support end users as they consider trial installations using A2L refrigerants. Features of Opteon™ XL20 Opteon™ XL20—the future of sustainable low- and medium-temperature refrigeration GWP of 148 (a 96% reduction versus R-404A)  Zero ODP Enables much higher charge sizes than highly flammable A3 refrigerants Is a close performance match to R-22 and R-404A Offers the optimum balance of performance and environmental sustainability Provides an easy, cost-effective alternative to legacy refrigerants in new equipment applications Utilizes well-known technology for ease of service and maintenance Benefits of HFOs Hensley was an early adopter of Opteon™ XP40, retrofitting equipment to experience better “Hensley was an early adopter of Opteon™ XP40, retrofitting equipment to experience better environmental outcomes, as well as high performance in low- and medium-temperature applications. Experiencing these benefits of HFOs whet their appetite to ask, ‘What next?’ With a strong dedication to supporting their communities and the environment while operating an efficient and thriving business, Hensley is a company that pushes the envelope." "Chemours was ready with our next-generation Opteon™ XL20—that will ensure they achieve maximum performance, operating efficiency, and sustainability," Joe Martinko President, Thermal and Specialized Solutions, Chemours. New low GWP refrigerant  “Our industry is undergoing some of the most significant regulatory changes in history and will be for the foreseeable future.
