Exair’s Dual High Temperature Cabinet Cooler Systems purge and cool overheated electrical control panels in harsh environments up to 200°F. Cabinet Coolers keep electrical enclosures cool with air as cool as 20°F, in order to eliminate high temperature malfunctions and protect sensitive electronics from hot, dirty locations. The high cooling capacity of up to 5,600 Btu/hr. is intended for large electrical enclosures and high heat loads. Models with lower cooling capacities for NEMA 12, 4, and 4X enclosures are also available.
Cabinet Coolers incorporate a vortex tube that cools ordinary compressed air to cold air without the use of refrigerants. They mount through a standard electrical knockout while maintaining the NEMA 12, 4, or 4X rating of the enclosure. Systems with thermostat controls minimize compressed air use, keeping the enclosure at ± 2ºF of the temperature setting. An automatic drain filter separator ensures no moisture passes to the inside of the electrical enclosure. There are no moving parts to wear out.
Dual High Temperature Cabinet Coolers are available with cooling capacities of 4,000, 4,800, and 5,600 Btu/hr., and are UL Listed and CE compliant. Applications include variable frequency drives, programmable controllers, industrial computers, motor controls, microprocessors, and robotics.
