CCV readings were also taken after the cleaning to monitor improvements PURE-Steam AHU and Coil Cleaning - The first step was to HEPA-vacuum the interior of the AHUs. Next, airflow resistance readings were taken across the cooling coils. This is known as a Coil Cleanliness Verification test, or CCV. Second, the interior of the unit was masked off and sanitized with WTI Pure Air’s proprietary PURE-Steam process. This included a deep cleaning of the cooling coils as well. PURE-Steam utilized bio-enzyme treatments and high temperature, low-pressure steam to penetrate through debris that was deeply lodged in the coil. Last, CCV readings were also taken after the cleaning to monitor improvements. In total, this process effectively optimizes AHU performance, cleanliness, and indoor air quality. Air handlers safely High-Performance Coatings - The next step in the hospital air handler restoration process was the refinishing of all the metal components of the units. This included the condensate or 'drain' pans, as well as the exterior. It was done with high-performance, multi-part polyurethane coatings designed and tested for use in HVAC equipment. They are antimicrobial, corrosion resistant, and have a very low odor to extend the useful life of the air handlers safely and effectively. Outside air dampers Outside Air Dampers and Controls - Finally, the AHUs were retrofitted with new outside air dampers which also included upgrades to the control components and system. In conclusion, hospital air handler restoration from WTI | Pure Air Control Services helped SiteLogIQ and the hospital refurbish two AHUs in much less time than replacing and with a significant 76% capital avoidance! Where two brand new AHUs would have cost the hospital $350,000 or more, the hospital saved $266,000 in capital by restoring them with HVAC New life for $84,000. Now the hospital has peace of mind in two restored units with five-year warranties that will provide many more years of service for their patients and staff.

Ensuring a healthy learning environment is crucial for the well-being of students and staff in any K-12 school system. One key aspect often overlooked is indoor air quality (IAQ), which directly impacts the health, focus, and productivity of everyone within the school community. In this blog article, Pure Air Control Services will explore the recommendations provided by the U.S. Environmental Protection Agency (EPA) for improving indoor air quality in schools, with a specific focus on the indispensable role Heating, Ventilation, and Air Conditioning (HVAC) systems play in achieving these goals. Importance of Indoor Air Quality in Schools Indoor air quality significantly influences the health and well-being of students and staff Indoor air quality significantly influences the health and well-being of students and staff. Poor IAQ can lead to respiratory issues, allergies, and even affect cognitive function. The U.S. Environmental Protection Agency (EPA) emphasizes the need for schools to prioritize indoor air quality (IAQ), in order to create a conducive learning environment. EPA’s Recommendations The U.S. EPA provides comprehensive guidelines for schools to enhance indoor air quality (IAQ). These recommendations include regular maintenance of HVAC systems, proper ventilation, use of air purifiers, and monitoring of indoor pollutant levels. These measures collectively contribute to a healthier indoor environment. HVAC Systems and Their Role: HVAC systems play a pivotal role in maintaining good indoor air quality (IAQ). Regular maintenance, including filter replacements and system cleaning, is essential to ensure that the HVAC system functions optimally. Proper ventilation, facilitated by well-maintained HVAC systems, helps in reducing the concentration of indoor pollutants. Ventilation Strategies: Effective ventilation is the key to a healthy indoor environment. HVAC systems should be designed and operated to provide adequate outdoor air exchange. The EPA recommends ventilation rates based on the number of occupants and the size of the space, emphasizing the need for schools to adhere to these guidelines. Filtration and Air Cleaning: High-efficiency air filters, when regularly replaced, can significantly reduce the presence of airborne particles and allergens. Additionally, the use of air purifiers equipped with HEPA filters can provide an extra layer of protection, further contributing to improved indoor air quality. Monitoring and Management: Regular monitoring of indoor air quality (IAQ) is essential to identify and address potential issues promptly. Many modern HVAC systems come with built-in monitoring capabilities, enabling facility managers to stay proactive in maintaining a healthy indoor environment. However, it’s equally important to regularly assess the cleanliness and performance conditions of air handler units and ductwork. Conclusion Prioritizing indoor air quality (IAQ) in schools is not just a matter of compliance; it’s an investment in the health and academic performance of students and staff. By following the EPA’s recommendations and focusing on the role of HVAC systems, schools can create a learning environment that nurtures both physical well-being and educational success. For their part, Pure Air Control Services (WTI Pure Aire) can help assess, clean and restore HVAC systems!

In the world of facility management, maintaining the optimal performance of air handler units is crucial. One key aspect that often gets overlooked is the cleanliness of cooling coils. Dirty cooling coils can lead to reduced efficiency, increased energy consumption, and compromised indoor air quality. In this article, they will explore three main ways cooling coils in air handler units get dirty and discuss effective solutions, with a focus on high-temperature, low-pressure steam cleaning. Three Main Culprits of Dirty Cooling Coils Filter Bypass: One of the primary culprits behind dirty cooling coils is filter bypass. Air filters are designed to trap dust, debris, and other contaminants, preventing them from entering the air handler unit. However, when filters are improperly installed or damaged, particles can bypass the filter and accumulate on the cooling coils. This not only hampers the unit’s efficiency but also poses a threat to the overall system. Cabinet Infiltration: Another common cause of dirty cooling coils is cabinet infiltration. Air handler units are housed in cabinets to protect them from external elements. However, if the cabinet is not properly sealed or if there are gaps and cracks, airborne particles from the surrounding environment can infiltrate the unit and settle on the cooling coils. Regular inspection and maintenance of cabinet seals are essential to prevent this form of contamination. Microbial Growth: Beyond the obvious dust and dirt, microbial growth presents a less visible but equally problematic issue. When moisture is present in the system, it creates an environment conducive to the growth of mold and bacteria on the coils. This biological contamination not only hinders efficiency but can also pose health risks. Proven Solutions Addressing Filter Bypass: Regularly inspect and replace air filters as recommended by the manufacturer. Ensure proper installation of filters and fix any gaps or leaks around them. Sealing Cabinet Infiltration: Conduct thorough inspections of the air handler unit’s cabinet for gaps and seams. Seal any openings with appropriate materials to prevent unfiltered air from entering. Controlling Microbial Growth: Manage moisture levels by fixing leaks and ensuring proper drainage. Conduct a deep steam cleaning of the dirty cooling coils. Incorporate UV light sterilization systems to inhibit microbial growth on coils. Steam Coil Cleaning To effectively clean dirty cooling coils, consider the use of high-temperature, low-pressure steam. This method offers several advantages: Efficiency: Steam efficiently dissolves and lifts dirt, even from hard-to-reach areas. It also restores airflow! Environmentally Friendly: Uses eco-friendly bio-enzymes compared to traditional cleaning methods. Minimizes Coil Damage: The gentle nature of steam cleaning prevents damage to delicate fins and coils. Longevity and efficiency For HVAC maintenance, understanding the common causes of dirty cooling coils is essential for ensuring the longevity and efficiency of air handler units.  By addressing filter bypass, cabinet infiltration, and outdoor air contamination, and implementing regular high-temperature, low-pressure steam cleaning, contractors can keep cooling coils in optimal condition, pioneering improved system performance and energy savings.
