Cabinet CoolerCabinet coolers with 2,800-Btu/hr. capacity incorporate a vortex tube that cools ordinary compressed air to 20° F. They mount to NEMA 12, 4 or 4X (stainless steel) enclosures through a standard electrical knockout. Systems include an automatic drain filter/separator to ensure no moisture passes to the inside of the electrical enclosure. A thermostat control minimizes compressed air use and keeps the enclosure at ±2º F of the temperature setting.
