Tampa, FL — Rising energy costs, lower maintenance budgets and decreased indoor air quality are challenges facing every facility manager across the country. But potential savings can be right under an organizations nose. Because dirty coils are difficult to clean, expensive to operate, unhealthy and can lead to humidity control deficiencies, it makes sense to

minimize the amount of dust that can enter the airflow and to clean them before dirt accumulation becomes visible.

Why are Clogged Cooling Coils Important: Cooling coils use tubing arranged in a series of loops and fins and their purpose is to transfer heat from one fluid to another (e.g. water to air, refrigerants to air, air to air etc.). The coils are where the system provides for the actual transfer of heat and moisture removal. Aluminum and copper fins are attached to the coils to increase the exposure surface and the rate of heat transfer. In the 1970s and early 1980s the cooling coils had typically 8 to 12 fins per inch, but due to increasing energy costs and mandated energy efficiency ratings, it is not uncommon seeing coils today manufactured with 16 and 18 fins per inch arranged in complex zigzag patterns. Unfortunately, these high efficiency coils are extremely susceptible to blockage from dust accumulation because once lodged deeply within the fins bacteria and mold may initiate growth, which not only compounds the blockage problems but also gives rise to excessive operating costs, comfort control problems and unhealthy sanitary conditions that are not conducive to good air quality.

Just about everything that contacts the coil surface can have an insulating effect. Pollen, dirt, grease, dust, corrosion, cigarette smoke, bacteria, fungi, viruses can act as an insulating

barrier. All debris must be removed for the system to perform its function efficiently. .Every part of an operating system must function properly to accomplish its cooling job effectively. However, Anything that insulates against heat transfer robs the system of its efficiency, ultimately increases operating cost, and increases the likelihood of equipment failure.

Conventional Coil Cleaning: Conventional coil cleaning with chemicals and detergents can have a detrimental effect on the coils and can only clean the face surface of the coil and do not provide a deep cleansing.

PURE-Steam Coil Cleaning and Flushing: Performing a deep cleansing with PURE-Steam Coil Cleaning and Flushing a super heat process of 350 degrees at 350 PSI can dramatically reduce energy costs, while improving in indoor air quality and without the use of chemicals. Florida State University (FSU) was able to payback their steam coil cleaning investment in less than 8 months.

Energy Savings: With energy costs rising, Florida State University (FSU), a major Florida university, took a close look at HVAC maintenance, including the total operating cost of its HVAC system. They found that the conventional coil cleaning foam/rinse method only superficially cleaned the surface of the coil and pushed small debris further into the coil causing decreased air flow, a musty odor, decreased temperature and humidity control and decreased the quality of the indoor air.

The forward thinking Facilities Management Department at Florida State University (FSU) felt these dirty coils were nothing but a pot of gold buried in dust and debris in these air handling systems. FSU discovered quickly that professionally steam cleaning their evaporator coils has paid huge dividends for them. They found a chemical free steam coil cleaning process so efficient and safe for the environment that in the first year of its implementation alone saved the university over $800,000 of their power bills and were able to provide the students and teachers a healthier learning environment. The estimated payback in less than eight (8) months was 157% return on investment (ROI).

The WOW Factor: At a VA Medical Center the facilities management team was so impressed with the PURE-Steam Coil Cleaning process that they stated: “All I can say is WOW; everyone on the team exceptional. The leader of the cleaning crew was very impressive and paid attention to details (this is important hospital environments). The whole experience was nothing short of outstanding.”

Pure Air Control Services (PACS), an industry leader in environmental and mechanical cleaning technologies recommends not to defer coil cleaning to the point that dust accumulation is visible. Minimally, heat exchangers should be cleaned once a year using the superheated steam process. For non specialized environments (healthcare facilities, clean rooms, etc.), Pure Air Control Services also recommends using air filters with an equivalent Minimum Efficiency Rating Value (MERV) of 8 and to minimize the amount of air that could infiltrate in the air handler by ensuring that the filters fit snugly in the holding racks and sealing all cabinet penetrations.

Improve Indoor Air Quality: Charlotte County School District has implemented a “Green Cleaning” program to not only save energy but also to improve indoor air quality and mitigate long-term health risks and allergies associated with indoor air pollutants. This program introduces a chemical free coil cleaning process called PURE-Steam Coil Cleaning a safe and effective cleaning process used to save energy and create a healthy learning environment for students, school staff and visitors.

As a part of this initiative, the Charlotte County School District has contracted with Pure Air Control Services a national leading indoor environmental contractor with over 25 years of

building IAQ experience. Because the PURE-Steam Coil Cleaning program is totally GREEN (NO CHEMICALS) students, school staff and visitors don’t have to worry about potential dangerous chemicals or Volatile Organic Compounds (VOC) entering into the air or water system.

Don Terry, Manager of HVAC Maintenance noted that “not only are we saving energy, but we are creating a healthy learning environment for our students and faculty.”

The U.S. Environmental Protection Agency (EPA) has long been a proponent of improving indoor air quality in the nation’s schools stating on their website that “Poor indoor air quality (IAQ) can cause illness requiring absence from school, and can cause acute health symptoms that decrease performance while at school. In addition, recent data suggest that poor IAQ can reduce a person’s ability to perform specific mental tasks requiring concentration, calculation, or memory.” Indoor air quality (IAQ) is a critically important aspect of creating and maintaining quality school facilities.

Additionally, Mr. Terry stated that “your staff, crew and support team are great to work with. I would highly recommend your Pure-Steam Coil cleaning process to any facility/HVAC manager interested in saving energy, improving indoor air quality and creating a healthy school.”
