For those climates where the calendar is filled with days of moderate temperatures, the RRS “Cool Free” is the perfect residential product to let Mother Nature cool your house instead of spending money running your entire HVAC system.
The Cool-Free residential economizer is installed with the home’s existing heating and cooling system, and during normal heating or cooling operation the Cool-Free can be set to either close completely so no outside air is brought into the home or bring in a small amount of outside air to help with indoor air quality. But the real benefit of the Cool-Free is when the temperature outside is cool but the house needs cooling - when these conditions exist the system will automatically open the damper and bring in the cool, fresh outside air and turn off the energy-burning compressor. The result is a cool and comfortable house without the cost of running the air conditioning unit. Energy savings. Comfort. Now that is a “cool” product.
