Type 316 corrosion-resistant side-mount kits enable mounting of a NEMA 4X cabinet cooler when an electrical enclosure has limited space on the top or side. The compact cabinet cooler protects sensitive electronics from heat, dirt and moisture and converts an ordinary supply of compressed air to 20 °F without refrigerants or CFCs. The cold air is circulated through the enclosure to eliminate high-temperature malfunction. Cooling capacities up to 5,600 Btu/hr are available. The UL-listed cabinet cooler systems include a compressed-air filter to assure no moisture or dust is introduced inside the panel. Optional thermostat control minimizes compressed-air use.
