Cabinet coolers with digital control resist heat, corrosion
Exair’s new Small 316 Stainless Steel Cabinet Cooler® systems with electronic temperature control (ETC) keep electrical enclosures cool with 20-degrees-F air while maintaining the NEMA 4X rating of the enclosure and resisting the heat that could adversely affect the internal components. The 316 stainless steel resists wear, corrosion, and oxidation.
Cooling capacities up to 550 Btu/hr. are suitable for small enclosures and heat loads. Models with higher cooling capacities up to 5,600 Btu/hr. for NEMA 12, 4, and 4X enclosures also are available.
The ETC maintains a constant temperature in the electrical enclosure that is slightly under the maximum rating of the electronics. It permits just enough cooling for the electronics without going so cold as to waste compressed air.
