to produce allergy-like symptoms, coughing, wheezing, watery eyes, asthma type conditions and other symptoms in building occupants. Fouled coils lead to increased pressure drop across them. Increased pressure drop increases fan horse-power requirements, which, in turn, draw more power, increasing current consumption.

Energy SavingsA recent article in the ASHRAE Journal authored by Ross Montgomery, PE entitled Study

revealed a $40,000 a year savings from just one air handling system as a result of the restoration of the air handler/coil system at the 1500 Broadway a 34 story skyscraper building in Times Square, New York City home to ABC Studios and Good Morning America. In addition, the study indicated that they were able

The Pure-Steam Process is “saving 7-10% on the chilled water equipment. Some of this is from reduced fan energy and the rest is from an increased delta T across the coil which reduces pumping energy and

35-40% of our utility bills are for HVAC sojust keeping our coils clean should shave

annually, at the low end”.

“as for ROI (return on investment) if you use the most conservative numbers we have paid approximately $0.14 per square foot for coil cleaning to date. We have saved about $0.22 per square foot annually. So the payback is less than 8 months and the ROI 157% annually.”

of coil cleaning

With energy costs rising, Georgia Tech University had taken 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 super�ciallly cleaned the surface of the coil and pushed small debris further into the coil causing decreased air �ow, musty odor, decreased temperature and humidity control and decreased the quality of the indoor air. In addition, GT was concerned about the thousands of gallons of chemicals that would otherwise be sent in the water system polluting the eco system.

Coil cleaning process

Improved Indoor Air QualityEvaporator coil bio-mass leads to a musty earth-like smell sometimes known as “Dirty Sock Syndrome” a primary cause

These pollutants are known to cause allergy-like symptoms, coughing, wheezing, upper respiratory irritation, watery eyes, asthma-type conditions and other symptoms in building occupants and in healthcare facilities nosocomial infections.

Energy SavingsFouled coils lead to increased pressure drop across them. Increased pressure drop increases fan horsepower require-ments, which, in turn, draw more power, increasing current consumption.

FSUimplementation 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 months was 157% return on investment (ROI). -- FSU Facilities Management Department
