Enclosure cooling system keeps keep electrical enclosures cool with 20°F (-7°C) air while maintaining the NEMA 4X rating of the enclosure. The small, 316 stainless steel cabinet cooler system with Electronic Temperature Control (ETC) helps resists the heat that could adversely affect the internal components. The wear, corrosion and oxidation resistance of Type 316 stainless steel helps ensure long life and maintenance-free operation. Cooling capacities up to 550 BTU/hr make the coolers suitable for small enclosures and heat loads. The line also includes models with cooling capacities up to 5600 BTU/hr for NEMA 12, 4 and 4X enclosures.
