EXAIR Cabinet Coolers for electrical enclosures

EXAIR’s Cabinet Cooler systems can be used to purge and cool electrical control panels. They convert an ordinary supply of compressed air to cold, -7°C air, without refrigerants. The cold air is circulated through the enclosure to eliminate heat damage and control shutdown. 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 user’s control panel.

The systems can be customised to provide cooling within electrical enclosures in NEMA 12, NEMA 4, NEMA 4X and hazardous location environments. These customisations include specific Btu/h values from 275–5600 Btu/h, adaptations for high-temperature environments up to 93°C and a selection of materials, including aluminium, Type 303SS and 316SS, to combat corrosive environments. Additional customisations include settings to maintain a specific cabinet temperature, special coatings, high-temperature materials, special cold air distribution kits and more.

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

Applications include cooling PLCs, microprocessors, variable frequency drives, industrial computers and robotics. All systems are UL Listed and CE compliant.
