Air-to-Air Heat Exchangers for Enclosures


AutomationDirect has expanded its Stratus™ line to include air-to-air heat exchangers in 120VAC and 24 VDC models. This air-to-air heat exchanger series is a closed-loop cooling system which employs the heat pipe principle to exchange heat from an electrical enclosure to the outside. Each heat pipe has an evaporator section and a condenser section which are separated by a permanent baffle so as to provide a closed loop. 

The coil systems use aluminum end plates and baffles which improve conduction and reduce corrosion for longer life. Air-to-air heat exchanger prices start at $1,028.00 and are available in models for use with NEMA 4 and 4X enclosures. Units are offered in three frame sizes (compact, deep, and tall) up to 72 Watt capacity, and are equipped with two circulating fans with sealed overload protectors.
