Integrated Free-cooling

CWB FC units consist of a standard refrigerated fluid chiller coupled with a free-cooler (dry cooler) in a single, air-cooled package. As the ambient temperature falls below the desired fluid temperature, the free-cooling circuit is engaged. A microprocessor controller seamlessly adjusts the amount of free-cooling (from 0% to 100%); the lower the ambient temperature, the greater percentage of heat load that is absorbed in the free-cooler. When operating in 100% free-cooling mode, the only cost of cooling is for the fans, providing substantial energy savings. CWB FC models share many of the features and options of the CWB line and are available in rated capacities to 70 tons.
