Compact NEMA 12 cabinet coolers resist heat, dirt

April 16, 2014
New from Exair.

New from Exair, the Small NEMA 12 Cabinet Cooler Systems keep electrical enclosures cool with 20°F (-7°C) air while resisting heat and dirty environments that could adversely affect the internal components. According to the company, the compact, durable cabinet cooler system provides a low-cost, easy to install, maintenance-free solution for enclosures in hot, remote and/or dirty environments.

Exair's Cabinet Coolers circulate 20°F (-7°C) air throughout the enclosure to prevent high temperature malfunctions. The systems' cooling capacity of up to 275 Btu/hr is ideal for small electrical enclosures with problematic overheating. Models with higher cooling capacities are also available.

The coolers mount through a standard electrical knockout while maintaining the NEMA 12, 4 or 4X rating of the enclosure. The systems include an automatic drain filter separator to ensure no moisture passes to the inside of the electrical enclosure. An optional thermostat control minimizes compressed air use and keeps the enclosure at ± 2ºF of the setting.

The Small NEMA 12 Cabinet Cooler Systems from Exair are available in 275 and 550 Btu/Hr versions and are UL listed and CE compliant. There are no moving parts to wear out with the systems, notes the company. Common applications include cooling control panels, PLCs, microprocessors, fractional Hp variable frequency drives, and robotics.
