Custom cabinet coolers for electrical enclosures

EXAIR’s Cabinet Cooler systems, said to be the low-cost way to purge and cool electrical control panels, now come with new options.

The devices convert an ordinary supply of compressed air to cold, -6°C air without refrigerants. The cold air is circulated through the enclosure to eliminate heat damage and control shutdown. Applications include cooling PLCs, microprocessors, variable frequency drives, industrial computers, and robotics.


Cabinet Cooler systems can be customized to provide cooling within electrical enclosures in NEMA 12, NEMA 4, NEMA 4X and hazardous location environments.

These customisations include specific Btu/Hr values from 275-5600 Btu/hr, adaptations for high-temperature environments up to 93°C, and a selection of materials including aluminum type 303SS and 316SS to combat corrosive environments.

For dirty and dusty environments, a non-hazardous purge option will create a positive pressure inside the cabinet to keep dirt and debris from entering the control panel. All systems are CE compliant.

Additional customisations include settings to maintain a specific cabinet temperature, special coatings, high temperature materials, special cold air distribution kits and more.

The systems can be installed in minutes through a standard electrical knockout hole. Optional thermostat control minimises compressed air use. There are no moving parts to wear out and no maintenance is required.
