Dry Coolers
This article discusses using devices known as “waterside economizers” and “dry coolers” as means to achieve “free-cooling”. Free cooling (sometimes referred to as a “free cooling system”) can reduce energy consumption and operating costs by using cold ambient air in lieu of running chiller compressors for cooling loads.
It is widely recognized that compressed air systems account for ten percent of all electricity and roughly sixteen percent of U.S. industrial motor system energy use. Seventy percent of all manufacturing facilities in the United States use compressed air to drive a variety of process equipment.
