The Stratus line of air-to-air heat exchangers now includes 120VAC and 24VDC models. The product is a closed-loop cooling system that 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 that are separated by a permanent baffle to provide a closed loop. The coil systems use aluminum end plates and baffles, which the company says improve conduction and reduce corrosion. Available in models for use with NEMA 4 and 4X enclosures, the exchangers are offered in compact, deep, and tall frame sizes with up to 72W capacity, and feature two circulating fans with sealed overload protectors.
