Corrosion-resistant Type 316 side-mount kits make the mounting of a NEMA 4X cabinet cooler possible when an electrical enclosure has limited space on the top or side. The compact coolers can purge and cool electrical control panels, protecting sensitive electronics from heat, dirt and moisture. They convert an ordinary supply of compressed air to 20°F (-6°C) 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 systems include a compressed air filter to ensure moisture or dust is not introduced inside the panel. Optional thermostat control minimizes compressed air use.
