AW 250SC-AW 450SC

Air cooling and water heating

The AW 250SC and AW 450SC are compact wall mounted air cooling units, and are ideal for cooling air in a number of commercial applications where the need for hot water enables heat recovery to a hot water tank. Designed for use in beer cellars, produce storage, kitchens and small hot water plant rooms. These units function by providing a cooled air stream to the area that requires cooling. The energy collected from the area is then upgraded through the heat pump cycle and used to preheat a mains hot water supply to the premises.
