Small 316SS Cabinet Coolers Resist Heat and Corrosion

Exair Corp.'s small 316 stainless steel cabinet cooler systems with ETC (electronic temperature control) keep electrical enclosures cool with 20°F (-7°C) air while maintaining the NEMA 4X rating of the enclosure and resisting the heat that could adversely affect the internal components. The wear, corrosion and oxidation resistance of Type 316 stainless steel assures long life and maintenance free operation, the company says. Cooling capacities up to 550 Btu/hr. are ideal for small enclosures and heat loads. Models with higher cooling capacities up to 5600 Btu/hr. for NEMA 12, 4 and 4X enclosures are also 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, the company says. A digital LED readout displays the temperature of the electrical enclosure (°F or °C), then displays the user temperature setting when pressing the “push to set” button. When that setting is exceeded, the cabinet cooler system is activated. Cabinet cooler systems include an automatic drain filter separator to ensure no moisture passes to the inside of the electrical enclosure.

Small 316 stainless steel cabinet coolers are available with cooling capacities of 275 and 550 Btu/hr. and are UL Listed and CE compliant. According to the company, there are no moving parts to wear out and applications include cooling control panels used in food processing, pharmaceutical, foundries, chemical processing and other corrosive locations.
