RETURN AIR DEFROST HOODS
As much as 60% of the energy used to defrost air coolers is lost to the room due to convection of heated air. Colmac Coil has developed a device which captures and uses the majority of this heated air. The Colmac Return Air Defrost Hood is a fully insulated series of hinged panels which collapse for shipment and then open quickly and easily into the operating position. The sturdy panels are of insulated double-wall construction with active heating to prevent condensation and frosting on the interior surfaces of the hood during defrost. Colmac Return Air Defrost Hoods can be added as an option to any A+Series™ air cooler.
