Side Mount Kits make the mounting of a NEMA 12 Cabinet Cooler possible when an electrical enclosure has limited space on the top or side. The compact Cabinet Cooler is a low cost way to 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 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. 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. Cabinet Coolers are UL Listed and have no moving parts to wear out. Side Mount Kits maintain the NEMA 12 rating of large and small electrical enclosures. Models for use on NEMA 4 and 4X enclosures are also available. Applications include cooling PLCs, microprocessors, variable frequency drives, industrial computers, and robotics. Side Mount Kits start at $69.
