Evaporative Pre-Cooling for Commercial AC Systems
The Award Winning PreChill™ System uses the power of evaporation to lower the temperature of the air cooling the condensers. The PreChill™ misting nozzles spray a fine mist into the air around the condensers only when the condenser fans are running. This cools the air 15° to 25° Fahrenheit. The electricity used by air-cooled HVAC Units is directly related to the outside air temperature. The hotter it is, the harder the cooling equipment has to work and the more energy it uses.
With large air-cooled HVAC equipment, there is 1.3% to 1.5% electrical demand and energy reduction for each degree Fahrenheit the temperature is reduced. Accordingly, any operating air conditioning equipment will use from 25% to 35% less energy at 75° than it does at 95°.

WHAT OTHERS SAY...
One of my neighbors installed a PreChill misting system on his 5 ton residential air conditioner and was bragging about how much money it was saving him each month. So I decided to look into installing a PreChill System on my home air conditioner and learned that the PreChill was designed predominantly for commercial use. I had them come to the restaurant that I owned and give me a quote. The PreChill was installed that week and has saved me more than $18,000 over the last 2 years. An additional benefit besides the lower power consumption is that the AC condenser coils never need cleaning with the PreChill System in place. I am so glad my neighbor was bragging about his AC.

D N Property Management Group manages office and residential facilities in the Southern Utah area. As a property management company, one of our challenges is controlling utility costs, especially air conditioning expense in the summer. With this in mind, we installed a PreChill misting system on one of our office buildings in Salt Lake City in the spring of 2012. We carefully monitored the power usage as well as the demand charge and were pleased to find that our air conditioning power costs were reduced by 28% from the previous year and almost 30% from the previous 3 year average. This resulted in a return on investment from the PreChill System of less than one year! We have since installed the PreChill System on all of our properties with air cooled condensers with similar results.

In the spring of 2011, our 25,000 sq. ft. office/manufacturing facility in Las Vegas was in need of additional air conditioning to maintain a constant temperature for an upcoming project that summer. The building was being cooled by five 25 ton units which were unable to provide enough cooling in July and August. HVAC consultants recommended adding an additional 20 tons of cooling. Due to the cost and ducting complications of adding another AC unit, we installed a PreChill misting system on our current HVAC units to see if we could increase the cooling capacity. If it didn’t work, we could add more air conditioning before it was needed in mid-July. By the middle of June it was apparent that our problem was solved. Not only did we have more than enough cooling capacity, but our power usage was at least 25% less. Not only did we avoid the expense of additional air conditioning, we also saved enough on our power bill that summer to more than pay for the cost of the PreChill equipment. Thank you, PreChill.
