EXAIR’s Dual High Temperature Cabinet Cooler® Systems purge and cool overheated electrical-control panels in harsh environments up to 200 F (93 C). Incorporating a vortex tube that cools ordinary compressed air to cold air without the use of refrigerants, they can be mounted through a standard electrical knockout while still maintaining the NEMA 12, 4 or 4X rating of the enclosure. Thermostat controls minimize compressed air use, keeping the enclosure at ± 2 F of the temperature setting. An automatic drain filter separator prevents moisture from passing into the enclosure. With no moving parts to wear out, maintenance issues are reduced. These new systems are available with cooling capacities of 4000, 4800 and 5600 Btu/hr, and are UL Listed and CE compliant. Applications include variable frequency drives, programmable controllers, industrial computers, motor controls, microprocessors and robotics.
