Exair Introduces Custom Coolers for Electrical Enclosures

Exair’s Cabinet Cooler systems can be customized to provide cooling within electrical enclosures in NEMA 12, NEMA 4, NEMA 4X and hazardous location environments, according to the company.

These customizations include specific Btu/hr. values ranging from 275-5,600 Btu/hr.; adaptations for high-temperature environments up to 200°F (93°C); and a selection of materials, including aluminum, type 303ss and 316ss, to combat corrosive environments. Additional customizations include settings to maintain a specific cabinet temperature, special coatings, high-temperature materials, special cold air distribution kits and more.  For dirty and dusty environments, a nonhazardous purge option can create a positive pressure inside the cabinet to keep dirt and debris from entering the control panel. All systems are UL listed and CE compliant.

Cabinet Cooler systems are designed to convert a supply of compressed air to cold, 20°F air without refrigerants. The cold air is circulated through the enclosure to eliminate heat damage and control shutdown.

Exair says the Cabinet Coolers can be installed through a standard electrical knockout hole. The thermostat control option is designed to minimize compressed air use. There are no moving parts to wear out and no maintenance is required, according to the company. These systems are suitable for cooling PLCs, microprocessors, variable frequency drives, industrial computers and robotics.
