Steam systems serve as the backbone of numerous industrial processes, providing the essential thermal energy required for a wide range of applications across various sectors. From powering machinery in manufacturing facilities to sterilizing equipment in healthcare settings, the importance of steam cannot be overstated. Improving Steam Operations American Plant Maintenance (APM Steam) offers specialized services aimed at optimizing steam systemsDespite their critical role, steam systems often operate below their maximum efficiency, pioneering to energy wastage, increased operational costs, and potential safety hazards. To address these challenges, American Plant Maintenance (APM Steam) offers specialized services aimed at optimizing steam systems. Rather than merely providing reactive maintenance solutions, they take a proactive approach, focusing on comprehensive optimization strategies that consider the entire steam system. Why Steam? The Science Behind Steam Systems Steam’s unique properties make it an excellent medium for transferring heat energy over long distancesSteam, often called the "invisible workhorse" of industry, is utilized in a myriad of applications, ranging from heating and sterilization to power generation and mechanical work. It's a versatile energy source, but its efficient use ruires a deep understanding of its properties and the intricacies of steam systems. At its core, steam is water in its gaseous state. Its unique properties make it an excellent medium for transferring heat energy over long distances. When water is heated to its boiling point, it undergoes a phase change, transforming into steam. When the reverse occurs, steam condenses to water. This process releases a significant amount of energy, which can be harnessed for various industrial applications. Core Steam Components Steam systems are composed of several key components, each with a specific role. Boilers, the heart of the system, generate steam by heating water. Piping is responsible for distributing the steam to different parts of the facility. Valves control the flow of steam, while heat transfer equipment ensures the energy is directed to where it's needed. Lastly, steam traps remove condensate to maintain efficient operation. Understanding the function of each component is crucial to optimizing the system. Challenges in Steam System Optimization One common issue is steam leakage, which can occur due to faulty valves, fittings, or failed piping. Steam leaks not only waste energy but also increase operational costs and pose safety risks to personnel. Another challenge is steam trap failure, which occurs when steam traps malfunction and fail to remove condensate from the system effectively or allow live steam to enter the condensate system. This can result to water hammer, uneven heating, and reduced steam quality. Identifying and addressing steam trap issues is essential for maintaining optimal system performance and a safe system. Additionally, improper system design and maintenance practices can contribute to inefficiencies in steam systems. Essential System Inspections Poorly insulated pipes, piping failures, poor piping practices, fouled (scaled) heat-exchanging surfaces, failed tube bundles or plates, failed condensate return pumps, inadequate ventilation, and equipment oversizing are common issues that can affect system performance. Regular maintenance and thorough inspections are crucial for identifying and rectifying these issues before they escalate. The Role of Optimization Services Specialized services aimed at optimizing steam systems are crucial for addressing these challenges effectively. Rather than merely providing reactive maintenance solutions, it is best to focus on comprehensive optimization strategies that consider the entire steam system. Steam trap surveys involve inspecting and testing steam traps to ensure they operate efficiently. This includes identifying failed traps and repairing or replacing faulty components to maximize performance. By maintaining properly functioning steam traps, facilities can minimize energy loss and reduce operating costs and operational interruptions. Evaluating Steam Performance System audits focus on evaluating the overall performance of steam systems, including pipe insulation, condensate return, air handler optimization, heat exchanger condition, and pressure-reducing stations. Engineers conduct detailed assessments to identify areas for improvement and develop tailored solutions to address inefficiencies. This may involve repairing or replacing failed equipment, upgrading equipment, or implementing other energy-saving measures. Preventative Maintenance Benefits Preventative maintenance programs aim to address potential issues before they result to system failures proactively. This includes regular HVAC and heat exchanger inspections, testing, cleaning, flushing, equipment lubrication, and monitoring system performance metrics to identify trends and patterns. By implementing preventive maintenance measures, facilities can minimize downtime, extend equipment lifespan, and reduce maintenance costs. Engineering Expertise: The Foundation of Optimization Steam system optimization lies a deep understanding of engineering principles and thermodynamics At the core of steam system optimization lies a deep understanding of engineering principles and thermodynamics. To that end, steam audits require a highly skilled team of field technicians and engineers who possess extensive experience and expertise in steam system dynamics. These professionals understand not only how steam systems operate but also why they function in specific ways. In a recent case study, APM Steam worked on a hospital where hidden steam traps had been malfunctioning for decades, unbeknownst to anyone at the facility. The condensate tank was overheating and blowing steam, and the issue had been overlooked for years. However, after a thorough inspection, the APM Steam team located the faulty steam traps and replaced them. APM Steam credited their methodical nature in finding the culprit. Fixing several small problems paved the way for the larger fix. Power of Fixing Small Issues This major fix resolved twenty years of malfunction and significantly improved the system's efficiency. This case highlights how addressing even small issues can yield substantial benefits over time. By leveraging their engineering knowledge, experts can identify inefficiencies, diagnose root causes of issues, and design solutions that enhance overall system performance. This approach goes beyond simple troubleshooting of individual components and considers the system as a whole, ensuring that all elements work harmoniously to achieve optimal efficiency. Comprehensive Optimization One of the key principles of steam system optimization is the importance of taking a holistic view. Instead of focusing solely on repairing or replacing malfunctioning components, it is best to comprehensively evaluate the entire system. By examining factors such as system configuration, original design considerations, and operational integrity, experts can identify underlying issues that may not be immediately apparent and develop strategies to address them effectively. Energy Efficiency Over Time Many facilities built in the 1960s, including pharmaceutical companies, hospitals, and universities constructed during the 1950s to 1980s, were originally well-built but without much consideration for energy efficiency. Over time, as technology evolved and energy efficiency became a priority, the knowledge of system operators and technicians dwindled. This lack of expertise proved detrimental to maintaining the original performance efficiency and operation integrity of these systems. Optimizing Legacy Infrastructure Despite being well-designed originally, changes in load, such as the increase in lab equipment and computers, as well as external factors like global warming, necessitated a fresh and comprehensive look at these legacy systems. While these systems have solid foundations, they require a thorough re-evaluation to rectify the issues that have accumulated over the years. It's crucial not to address symptoms merely but to recommission these systems with a focus on the original design, now with an emphasis on energy efficiency. Maximizing System Reliability In a community college built in the late 1970s, APM Steam was tasked with optimizing the steam system. Often, such facilities, built decades ago, pose challenges for local staff who may struggle to understand the layout and functioning of the system. The team addressed various issues, resulting to a drastic improvement in operational integrity and energy efficiency. These improvements were crucial as the college continued to expand. Comprehensive optimization extends beyond mere maintenance tasks. It involves proactive measures to ensure that steam systems are always operating at peak efficiency. This may include implementing preventative maintenance schedules, monitoring system performance metrics, and conducting regular audits to identify areas for improvement. The Importance of Expertise At the heart of a steam optimization regime is expertise: professionals who possess a deep understanding of steam system dynamics who can make informed decisions and implement effective solutions. Experts can offer an independent perspective and a fresh outlook on system optimization, resulting in unbiased assessments and recommendations tailored to specific needs. In addition to optimizing existing steam systems, expertise in steam system management is crucial during the design and commissioning phases of new installations. By involving experienced engineers from the outset, companies can avoid common pitfalls and ensure that systems are designed to operate efficiently from day one. Looking Towards the Future As industries continue to evolve and technology advances, the importance of steam system optimization will only grow. Companies that prioritize efficiency and sustainability will increasingly turn to specialized providers to ensure that their steam systems operate at peak performance. By prioritizing comprehensive optimization strategies and leveraging engineering expertise, companies can unlock significant benefits in energy efficiency, operational reliability, and overall cost savings.

Peace of mind when ordering parts for cooling equipment is an under-appreciated element of the industry. When replacing, upgrading, or retrofitting parts for the cooling systems, the parts being specially designed for the cooling units can make all the difference for the unit’s future performance. Unknown parts give unknown results, and getting factory-tested equipment directly from the manufacturer cuts out the unknown from the cooling system’s lifespan. Benefits for the end user There are often rigorous certifications to make sure they are getting a quality product There are significant benefits for the end user when ordering from the Original Equipment Manufacturer (OEM) as opposed to getting parts from a third party. With the original manufacturer, parts are factory-tested for quality before being made available to users. There are often rigorous certifications to make sure they are getting a quality product.  Purchasing directly from the source ensures that they have a knowledgeable vendor for the product, which reinforces any guarantees for compatibility and gives users access to a team with direct knowledge of that product and how it works. Net for customers' cooling systems Warranties can also be a great safety net for customers looking for upgrades or fixes for their cooling systems. Purchasing third-party parts runs a higher risk of incompatibility and part failure, and there is a significantly higher risk of those issues not being covered under a warranty. Getting technical support from the experts during installation can make upgrades much easier and drastically cut downtime for operations.  Incompatible fits and untested equipment Fitting units with parts not from the original manufacturer is a gamble Fitting units with parts not from the original manufacturer is a gamble. Manufacturers spend thousands of hours researching, testing, and improving parts to run optimally with cooling towers so that there can be sustained cooling performance. Third-party parts tend to fail earlier and perform worse than OEM parts, with incompatible fits and untested equipment being common faults, reducing the lifespan of the unit. BAC’s Series 3000 Cooling Tower A case study found that BAC’s Series 3000 Cooling Tower, when fitted with an outside vendor’s block fill, performed at just 72 percent of the original tower’s thermal capacity. The Series 3000 Tower traditionally uses a hanging fill as a surface area to evaporate water and reject heat, and the block style fill was comprised of corrugated PVC sheets with a lesser total surface area to evaporate water.  block fill and VersaCross® Fill BAC also offers a VersaCross® Fill, which is designed for the Series 3000 Cooling Tower BAC also offers a VersaCross® Fill, which is designed for the Series 3000 Cooling Tower to prolong the life and maintain efficiency in the unit. An independent testing company compared two units, one with the block fill and one with the VersaCross® Fill. To test the efficiency, both units, which are located at an NHL arena, were put under the stress of a packed game. OEM VersaCross® Fill unit The two 18-year-old towers performed very differently, with the third-party block fill unit having a reduction in thermal capacity to 72 percent of the original capacity, and the OEM VersaCross® Fill unit operating at 96 percent of the original unit thermal capacity. To show degradation over time, the block fill unit was tested 16 months and 28 months after installation, where it continued showing a significant performance drop-off. Reliability of OEM parts The reliability of OEM parts will play a major factor in getting the most out of the cooling towers With a lower initial installation cost, the block fill was an attractive first choice, but the additional energy consumption, maintenance costs, and reduced performance ultimately resulted in the user switching to BAC’s VersaCross® Fill.  Total cost of ownership versus initial cost is critical when considering replacement parts. Exact form, fit, and function make a big difference in maintaining a cost-effective cooling solution, and the reliability of OEM parts will play a major factor in getting the most out of the cooling towers. BAC’s CTI certified towers BAC has made significant efforts to expand and evolve the resources for its aftermarket team to give customers the best possible experience when purchasing parts and upgrades. From working with vendors to drop ship parts to customers in a seamless transition to fulfilling parts from any of BAC’s CTI certified towers, part warranties, and engineers across the globe continually pushing innovation, they can have peace of mind that the equipment is reliable and designed to keep the operations cool.

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.

For warehouse and factory owners, cutting their heat energy bills by over 90% might seem like a pipedream. I’ve been in enough warehouses to know one thing: heating them is expensive and frustrating. It often feels like throwing money into the wind. However, times are changing, and with the introduction of Shortwave Infrared (SWI), a revolutionary technology set to redefine warehouse heating, business owners can finally achieve energy savings on the scale they need.  Shortwave Infrared (SWI) For warehouse owners, slashing heat energy bills by more than 90% might sound far-fetched. Having spent time in countless warehouses, I know one thing: heating them is both costly and frustrating like throwing money into thin air.  But times are changing. With the arrival of Shortwave Infrared (SWI), a ground-breaking technology poised to transform warehouse heating, business owners can now achieve the substantial energy savings they've been seeking.  Beyond the Status Quo  Faced with soaring bills, warehouse, and factory owners are actively seeking better alternatives For years, warehouse heating has been stuck in a cycle of inefficiency opting for bulky systems that consume vast amounts of energy but offer little in return. High heating bills were once seen as an unavoidable cost of doing business. However, the energy price hikes of 2021 and 2022 completely changed the game, straining heating budgets and forcing a rethink of what's acceptable.  But there are positives to find in the situation. Faced with soaring bills, warehouse, and factory owners are actively seeking better alternatives.  Next-gen technology An industry long overdue for disruption has finally found the push it needed to embrace 'next-gen' technology. Enter Shortwave Infrared, ready to take the spotlight.  At the forefront of the heating revolution, it’s delivering unprecedented energy savings and cost efficiency, setting a new standard for businesses nationwide.  Lost in Translation  So, what sets SWI apart, and why does it outperform current systems? It all comes down to SWI's core heating principles. One of the most rewarding moments of my career was seeing the reaction of workers, shivering in a drafty space, suddenly feeling the warmth from SWI heaters. Their faces said it all – they couldn’t believe how something so simple could work so effectively.  However, the main issue is that currently, the warehouse and logistics sector largely depends on convection heating, which works by warming the air within a space. While this might be adequate for smaller, enclosed areas, it falls short in large, open-plan spaces where heat quickly dissipates.  Basic physics Turning up the thermostat won’t help either, as the principles are floored from the beginning It all comes down to basic physics, warm air rises. In buildings with high ceilings, this means heat drifts upwards, leaving workers on the ground cold, while the warmth stays out of reach. The issue is made worse by large doors and windows, which allow even more heat to escape.  For those lucky enough to be near a heater, it can be hit-or-miss. Turning up the thermostat won’t help either, as the principles are floored from the beginning. You’ll just be draining budgets quicker than before. SWI: A New Frontier  On the other hand, Shortwave Infrared Heating offers a revolutionary solution. By providing localized heat, it ensures workers stay comfortable and productive, regardless of the ambient temperature.​ Unlike traditional heating systems, SWI eliminates heat loss by targeting individuals directly – a feeling akin to the warm sun on your back. This strategic approach not only saves energy, but also creates a more comfortable workspace, making it an ideal solution for businesses seeking major efficiency and cost savings.  Cost and carbon savings Unlike convection heating, SWI also delivers consistent warmth, eliminating cold spots.  Additionally, its electric power source offers substantial cost and carbon savings, making it a sensible choice for those looking to align their heating systems with ESG initiatives.  The Verdict is In  By implementing SWIR, we helped them achieve a 90% reduction in energy consumption The good news is that the word is out, and companies are now reporting over 90% energy savings while drastically reducing their carbon footprints. A recent customer faced the challenge of heating a massive 5,000-square-meter space. By implementing SWIR, we helped them achieve a 90% reduction in energy consumption, exceeding expectations.  Annual energy consumption The numbers speak for themselves. Annual energy consumption dropped from 150,000 kWh (gas) to 16,000 kWh (electricity), showcasing the incredible potential for change in UK businesses. This is just one example, imagine what we can achieve rolling out SWI across the country,  The positive impact on the bottom line has prompted the company to implement SWI across all of its UK sites. As a sustainability-driven business, SWI provides a crucial solution to reduce reliance on carbon-heavy fossil fuels.  The Future is Bright  SWI's potential to transform warehouse and logistics is endless and businesses are now waking up to its potential, and are rightly being drawn in by the idea of significant cost and carbon savings. It’s a shift in mindset that’s challenging traditional heating methods. By focusing on precise, targeted warmth, rather than wasteful, resource-heavy convection heating, UK businesses are already saving millions of pounds each year.  Efficiency of infrared technological challenges Business owners are accustomed to thinking of heating as raising the overall temperature of a space Yet one of the biggest challenges the industry faces is a mental one, not a mechanical one. Business owners are accustomed to thinking of heating as raising the overall temperature of a space. However, this outdated approach fails to consider the efficiency of infrared technology, which delivers focused warmth directly to workers, equipment, or specific areas.  Impact of SWI I'm always thrilled to see the reactions of customers amazed by the impact of SWI. However, we need more people to embrace this innovative heating method, which means winning more hearts and minds.  For those ready to make the switch, the benefits will be substantial, potentially saving thousands, if not millions, on heating bills at a time when they need it most.

Data centers worldwide are under intense pressure. High-powered computing is a global necessity that seemingly gets more demanding by the day. There’s also the need to prioritize sustainability improvements ranging from resource conservation to decarbonization. And data centers must consider their bottom line and remain competitive. Anticipating the challenges data centers will continue to face, scientists and engineers have innovated two-phase (2-PIC) immersion cooling. With the capacity to meet the elevated cooling requirements driven by high-powered computing, this next-generation solution delivers on environmental priorities by significantly lowering data center energy consumption, slashing, if not eliminating, water use, while supporting decarbonization, circularity missions, and more. Emergence of 2-PIC Traditional approaches are fast approaching capacity for meeting current and future cooling needs The emergence of 2-PIC comes at a critical time, because the traditional cooling methods that have kept data centers up and running so far—namely air cooling and water cooling—are doing so at the detriment of the planet.  Additionally, these traditional approaches are quickly approaching capacity for meeting current and future cooling needs. Air- and water-cooling methods are used in approximately 95% of the estimated 8,000 data centers that exist today. The criticality of high-powered computing Once seen as a future need, high-powered computing, and faster-than-ever processing are now established as critical to the operation of businesses, governments, organizations, and other entities that support the way communities function, survive, and thrive. Whether it’s health and wellness, financial institutions, economic growth, safety and protection, entertainment, education, or any other service supporting our way of life, successfully providing that service fully depends on the ability of data centers to quickly and reliably obtain, store, and process data.  Influence of AI AI has a profound influence and, generates far more power than traditional internet uses Moreover, when we say “data centers,” we’re not just speaking of big players like Microsoft, Google, Meta, and Amazon. Equally dependent on high-performance, high-speed computing are enterprise data center operators, such as our governments and military, financial institutions, healthcare systems, educational institutions, and more.  We also must acknowledge the profound influence of artificial intelligence (AI), which generates far more power than traditional internet uses. Its effects are far-reaching, enhancing patient care, supporting risk management and fraud detection in finance, boosting crop yields within agriculture, and more. The environmental costs of data centers According to the latest estimates by the International Energy Agency, data centers worldwide produce 1% of energy-related carbon emissions and in 2022 used approximately 460 TWh of electricity per year—equating to 2% of global electricity demand. McKinsey and Company estimates 40% of this electricity is used for data center cooling. Data centers’ impact on the environment also includes their significant water consumption, averaging 300,000 gallons per day, and a physical footprint that averages 100,000 square feet but in the case of some hyperscale data centers can range between 1.3 to 2 million square feet. In terms of growth, a U.S. market report from Newmark tells us that in the U.S. alone, the U.S. data center footprint will absorb 35 gigawatts by 2030, which is more than twice the data center power consumption of 2022. The emergence of liquid cooling: the elevated interest in 2-PIC From reducing energy and water consumption to shrinking physical footprints, 2-PIC offers the planet a better data center solution. In less than two years, traditional cooling systems won’t be able to support the exponential growth in the world’s data processing and storage applications. Based on publicly available product roadmaps from major chip manufacturers, by 2026, air-cooled systems will no longer be able to meet the cooling needs of most next-generation, high-performance computing chips. Capable of removing heat more effectively than air cooling, liquid cooling uses a liquid such as water or a dielectric fluid to cool the heat-generating components of servers. The liquid can cool these components directly, or it can be done indirectly through a heat exchanger. With two-phase immersion cooling the entire server rack is submerged in a tank filled with a dielectric fluid. Single-phase and two-phase liquid cooling Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system. Two-phase liquid cooling uses a phase-change material, such as a refrigerant, which evaporates and condenses as it absorbs and releases heat. With 2-PIC, which is a form of two-phase liquid cooling, the entire server rack is submerged in a tank filled with dielectric fluid. The fluid boils as it’s heated by the components of the servers, creating bubbles that rise to the surface and condense in a heat exchanger. Gravity then returns the condensed fluid to the tank, creating a natural circulation loop that does not require pumps or fans. Advantages of 2-PIC 2-PIC is commanding attention as the solution for meeting the cooling demands of the high-powered computing components of today and tomorrow. Moreover, the technology of 2-PIC systems, combined with the right dielectric fluid, delivers advantages to “take the heat off” data centers. Here’s a breakdown of additional 2-PIC benefits: Up to 90% reduction in energy consumption: Based on modeling completed by the industry, 2-PIC is expected to reduce up to 90% of data center cooling energy consumption and 40% of overall data center energy consumption*. (*Compared to traditional air-cooling technologies) Enhanced computing performance and data center reliability: 2-PIC allows servers to operate at higher temperatures and power densities, while reducing the risk of overheating. Significant reduction in water consumption: Depending on the data center location and cooling design methodology, water consumption could even be eliminated completely. 60% reduction in the physical footprint: 2-PIC reduces the space required for cooling equipment, freeing up more floor area for servers and increasing the rack density of the data center. Lower GWP and circularity: Chemours Opteon™ 2P50 is a developmental dielectric heat-transfer fluid, currently pre-commercial, pending regulatory approval. It offers an extremely low global warming potential (GWP) of 10 and was specifically created to optimize the performance of the electronic components in a 2-PIC system. This 2-PIC fluid also enables the reprocessing/reuse of existing fluid to maximize circularity.  The bottom line: In addition to other compelling data, a recent study commissioned by Chemours and LiquidStack through Syska Hennessy, revealed that, compared with other state-of-the-art liquid cooling methods, 2-PIC can deliver up to a 40% lower total cost of ownership (TCO) and significantly reduce operational expenditures (OPEX), with savings ranging from 54% to 88.6%. Benefits of new data center cooling technologies compared to single-phase direct-to-chip, and single-phase immersion methods. 2-PIC, the future-ready solution As the world’s reliance on AI and other high-powered computing capabilities escalates, data center cooling solutions must grow with demand while significantly reducing their impact on the environment. In global energy savings alone, 2-PIC could generate an estimated savings of 340 TWh by 2055—the equivalent of powering more than 517 million laptops 24/7. And even with increasing IT loads, 2-PIC maintains its performance, ensuring long-term cost-effectiveness and adaptability to meet future demands. With society at a crossroads between the criticality of high-powered computing and a planet in crisis, the industry is turning its attention to 2-PIC as the solution for today and tomorrow.

Hydronics systems rely on water, steam, or water solutions to distribute heating and cooling throughout a building. They are inherently more eco-friendly than conventional alternatives. First and foremost, using water as a temperature regulation method is a natural choice. There is no carbon footprint involved in its creation, and there is no inherent danger in exposure to water in the event of a system failure. Water is more efficient at carrying heating and cooling loads than other technologies. Other benefits include a wider range of maintenance flexibility and longer system life expectancy. overall efficiency of hydronics  “A misconception about hydronics is that it's more expensive compared to other HVAC systems,” says Jim Nolan, market development manager, Xylem. “While hydronic systems may require a larger upfront investment, lifecycle costs are significantly lower due to the overall efficiency of hydronics.” Flexibility in Cold and Warm Climates Hydronics offers a wider range of flexibility for components, operation, and maintenance Compared to other systems, hydronics offers a wider range of flexibility for components, operation, and maintenance. That flexibility also extends to extreme climate conditions, says Nolan. Hydronics perform reliably at very cold and very warm temperatures for improved occupant comfort and reduced energy costs. Additionally, hydronic systems draw on water’s natural thermal storage capabilities, which can substantially offset operating costs during peak demand periods. For over 100 years, Xylem’s Bell & Gossett has been at the forefront of hydronic systems as a manufacturer of pumps, valves, heat exchangers, and accessories — including steam and heat transfer — for plumbing and wastewater applications. Since 1916, the company has made a name for itself through products, industry-pioneering training at the Little Red Schoolhouse, comprehensive solutions, and application expertise, says Nolan. Products and sustainability efforts “Xylem is continuously innovating to advance and embed sustainability holistically into our solutions – from the materials we source, to making them more compact and cutting emissions, to high-efficiency motors,” adds Nolan. Advancing the efficacy and efficiency of their foundational products is what Bell & Gossett is known for, and more broadly, what Xylem is doing to embed “high impact” into all its products and sustainability efforts, says the company. Quantifiable Effect on Decarbonization Smart pump solutions like Xylem’s Hydrovar® X Smart Motor tout ultra-premium efficiency As the built environment increasingly weighs the effects of climate change and decarbonization, products must keep pace to demonstrate quantifiable impact on addressing these challenges. Smart pump solutions like Xylem’s Hydrovar® X Smart Motor tout ultra-premium efficiency, sustainably sourced materials, and compact design, delivering high impact in terms of intelligence and productivity. Built-in condition monitoring empowers customers to leverage data for additional pump protection and optimized performance. Equally essential is continued education and collaboration with industry partners to help commercial building owners navigate the challenges of achieving decarbonization and net-zero goals, says Nolan. That includes training opportunities at Bell & Gossett’s Little Red Schoolhouse to teach industry professionals about sustainable solutions, he adds. Ideal distribution system “Water is considered technology agnostic – no matter what type of technology exists today or in the future, modern hydronic systems can easily adapt to a variety of energy sources,” says Nolan. “As solar and geothermal grow, building owners and designers are recognizing that hydronics provide an ideal distribution system for these alternative technologies to perform.” Hydronic system efficiency is already well-documented in thousands of real-world applications, says Nolan. Hydronics reduces operating costs by using water as a heat transfer medium, which is more effective than air. Efficiency and cost savings are maximized when these systems are powered by renewable energy sources. Overcoming Obstacles to Equipment Reuse In some cases, though, existing HVAC equipment may be too outdated for reuse In some cases, existing HVAC equipment can be reused to achieve sustainable, carbon-neutral systems, says Nolan. Adaptive reuse projects involve repurposing an existing building for new use and reusing as much existing equipment as possible to save costs, conserve resources, and minimize construction-related disruptions. Upgrading existing hydronic systems with smart technology like advanced controls and smart motors can improve performance and efficiency, says Nolan. Another option is to incorporate high-efficiency components like heat pumps. In some cases, though, existing HVAC equipment may be too outdated for reuse. In others, existing building footprints may limit design options. To overcome this, a thorough assessment of current building conditions and performance can provide a better understanding of the original system design. Identify ways to reduce energy consumption Energy audits, building performance evaluations and environmental impact assessments provide valuable insights into an existing building’s energy consumption, resource usage and environmental footprint. The purpose of these tools is to identify ways to reduce energy consumption or operating costs by upgrading to more energy-efficient equipment or by building a better system. “There’s a whole industry built around energy audits—they’re typically conducted by industry professionals who have qualifications or certifications to ensure they have the knowledge and skills to perform thorough and accurate assessments,” says Nolan. Challenges to Deregulation and Achieving Net Zero Deregulation or the elimination of natural gas in existing buildings presents challenges. While hydronic equipment is essentially decarbonized because it runs on electricity, many utilities still rely on fossil fuels. Only when those providers switch to renewable energy and the grid infrastructure is expanded to deliver enough electricity will environmental impact be realized.  Although many areas are moving toward decarbonization and achieving net-zero energy, in regions where energy is cheap, there are few incentives to embrace renewable energy and building electrification. As HVAC equipment becomes more efficient and uses less energy, communities will realize the cost savings and gravitate toward better technology.

Gaining early popularity in the 1970s, previous generations of heat pumps were only considered useful in mild climates. But today, modern heat pumps, especially variable-speed mini-split heat pumps, are reliable, sustainable, and used in various ways, including ways our parents and grandparents would never have thought of. New uses include she sheds, man caves, garages, tiny homes, sunrooms, and even boats.  We spoke to Sean Gallagher, Regional Sales Manager, Eastern Massachusetts, Mitsubishi Electric Trane HVAC US (METUS), to discuss how people use heat pumps in the U.S. and abroad. He described some of the technology's varied (and sometimes surprising!) uses.  Q: What are the most common applications of heat pumps on boats and marine crafts, and how do they differ from residential or commercial uses?  Gallagher: I know one Diamond Contractor® who installed a heat pump on his father’s yacht. Since my territory includes Southeast Massachusetts and Rhode Island, I frequently see heat pumps on the large car-carrying and passenger-carrying ferries. Although commercial applications like ferries are more common, I think we will see more heat pumps on people’s boats and yachts, especially since we use an anti-corrosion coating that protects the outdoor heat exchanger against salt, sulfur and other airborne contaminants that impact the efficiency and performance of outdoor units.   Q: What are some other "off-beat" or previously underappreciated applications for heat pumps – she sheds, man caves, garages, tiny homes, sunrooms, or something similar?  Heat pumps are being used in high-end campers like Airstreams, smaller campers, parking lot kiosks Gallagher: All those applications apply, and there’s plenty more. My niece lives in a 400-square-foot studio apartment over my garage that’s heated and cooled with a heat pump. I also installed a low, wall-mounted heat pump unit in my father’s tool and woodworking shed. Since his tools hang on the wall, he didn’t want to give up any wall space, so now, he has a climate-controlled workshop that suits his needs. Heat pumps are also being used in high-end campers like Airstreams, smaller campers, parking lot kiosks, food trucks, and even intermodal shipping containers turned into spaces like laboratories.   Q: What are the key advantages of using variable-speed mini-split heat pumps in smaller applications in various climates?  Gallagher: All-climate heat pumps can conquer any climate in New England and most of the United States. Overall, variable-speed mini-split heat pumps provide efficiency, ease of installation, comfort, and quiet, regardless of outdoor temperature. Some of the best heat pumps on the market provide warmth, even if the temperature drops to a chilly –22 degrees F. At the opposite end of the thermometer, heat pump systems can cool indoor spaces when it’s a scorching 115 degrees F.  Q: How does the equipment used for these applications differ from the equipment in more common HVAC use cases?  Gallagher: In most HVAC use cases, people use a unitary, conventional HVAC device to heat a home. However, the market has been moving away from unitary devices toward having custom control in every room. Think about if you turned on your kitchen faucet and every faucet in the house turned on, or if you turned on your bedroom light and every light in your home turned on with it. It’s inefficient, which is how unitary systems work. All-climate heat pumps give precise temperature control and custom comfort in any area, whether it’s a shed, man cave, or garage. Each person can heat or cool the space to their comfort level. This is how heat pumps work in general and in these off-beat use cases.  Q: How has the reliability of modern heat pump technology expanded the potential for marine and other applications?   One-to-one heat pumps are perfect for smaller applications because of their turn-down ratio Gallagher: Since Mitsubishi Electric’s Hyper-Heating INVERTER® (H2i®) technology is not new – having come out around 2009 – the technology has grown by leaps and bounds. Today’s one-to-one heat pumps are perfect for smaller applications because of their turn-down ratio. They can ramp up quickly and then throttle back to meet the needs of a space, through a setpoint, in heating and cooling to use only the energy necessary to maintain the comfort of that indoor space. Multi-zone applications can handle larger spaces with ease and efficiency.  Q: Can you provide examples of how heat pumps are being used on boats or marine crafts in the U.S. and abroad? What technologies are they replacing?  Gallagher: Heat pumps are replacing electric-resistance heat, gas-fired HVAC units, and hydronic systems for watercraft powered by steam. For cooling, heat pumps are replacing chilled water systems on larger ships. Heat pumps are frequently used on large car-carrying and passenger-carrying ferries. I also know of people who have installed them on yachts and other boats, which I think will become more prevalent.  Q: What are the challenges HVAC professionals might face when installing and maintaining heat pumps on boats and/or in smaller applications?  The biggest challenge they face is contending with the caustic nature of the saltwater environment Gallagher: For maritime applications, the biggest challenge they face is contending with the caustic nature of the saltwater environment. I mentioned this a minute ago, but salt can degrade non-ferrous metals, like copper and aluminum. It’s crucial to use an anti-corrosion coating that protects the outdoor heat exchanger against salt, sulfur, and other airborne contaminants that impact the efficiency and performance of outdoor units. Some companies specialize in taking heat pumps apart and coating all the parts that could corrode to prevent them from doing so. This makes the heat pumps last much longer than they otherwise would.  Q: How does the installation of heat pumps on boats align with the growing demand for energy-efficient and sustainable solutions in the marine industry?  Gallagher: Energy-efficient heat pumps consume far less energy than a conventional HVAC system. Heat pump systems cycle hot and cold air where it’s wanted depending on the season and provide personalized comfort on a boat year-round. Modern heat pumps, especially variable-speed mini-split heat pumps, are reliable and sustainable, providing high-performance heating and air conditioning on boats anywhere, even in extremely cold or warm climates. Heat pumps are preferable in most climates, as the efficacy of a heat pump is generally 1.5 to 4 times greater when compared with electric resistance heating. {##Poll1731297929 - Which of these applications for heat pumps seems most surprising?##}

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."

Renewable energy is derived from natural sources that are replenished at a higher rate than they are consumed. Examples include sunlight, wind, water, and geothermal heat. The use of renewables provides environmental benefits (such as lower greenhouse gas emissions), economic advantages, sustainability, and better energy security. As a significant consumer of energy, HVAC is well-positioned to promote greater usage of renewable energy sources. We asked our Expert Panel Roundtable: How can the HVAC market better embrace renewable energy?
