Exair Corp.’s dual 316 stainless steel cabinet cooler systems have electronic temperature control (ETC) to keep electrical enclosures cool with 20°F (-7°C) air while maintaining the NEMA 4X rating of the enclosure and preventing heat that could adversely affect the internal components. The company says the wear, corrosion and oxidation resistance of 316 stainless steel assures long life and maintenance-free operation within food, medical, pharmaceutical, chemical and other harsh environments. Cooling capacities up to 5,600 Btu/hr. are well-suited for larger enclosures and heat loads. The digital ETC is said to provide precise temperature control in the electrical enclosure, which is constantly being monitored by a quick-response thermocouple.

Other available models have cooling capacities up to 5,600 Btu/hr. for NEMA 12, 4 and 4X enclosures. Exair also offers hazardous location cabinet coolers which have a UL-classified listing. The line also includes nonhazardous purge models, high-temperature models, and continuous-operation and thermostat-controlled models. All cabinet cooler systems are UL listed and CE compliant.
