EXAIR NEMA 4 (IP66) Cabinet Coolers (dust-tight, oil-tight, splash resistant, indoor/outdoor service) incorporate a low pressure relief valve for both the vortex tube and cabinet air exhaust. This valve closes and seals when the cooler is not operating to maintain the NEMA integrity of the electronic enclosure. NEMA 4 (IP66) Cabinet Coolers are available in many cooling capacities for large and small control panels. Unlike an expensive, freon-based air conditioner, EXAIR Cabinet Coolers incorporate a vortex tube to produce cold air from compressed air - with no moving parts. They can be installed in minutes through a standard electrical knockout. NEMA 4 Cabinet Cooler® Systems are available with a thermostat control or as a continuous operation system. Each of these systems include a water-dirt filter separator to prevent water condensate and dirt from entering your enclosure and a cold air distribution kit used to direct the air for circulation or on to hot spots. All Cabinet Coolers are UL Listed and CE Compliant. They are a low cost, reliable way of cooling and purging electronic control panels.

Accessories:
EXAIR's Side Mount Kits make mounting on the side of an electrical enclosure possible when there is limited space on the top or side. (NEMA 4 and 4X Cabinet Cooler Systems must be mounted vertically.) Side Mount Kits maintain the NEMA rating of large and small NEMA Type 12, 4, and 4X enclosures. they mount in a standard electrical knockout (1-1/2 NPS). Side Mount Kits for NEMA 12 Cabinet Cooler Systems have an aluminum construction. Those for NEMA 4 and 4X Cabinet Cooler Systems are Type 303 or Type 316 stainless steel.
How It Works:
Compressed air enters the vortex tube powered Cabinet Cooler and is converted into two streams, one hot and one cold. Hot air from the vortex tube is muffled and exhausted through the vortex tube exhaust. The cold air is discharged into the control cabinet through the cold air distribution kit. The displaced hot air in the cabinet rises and exhausts to atmosphere through the cabinet air exhaust at a slight positive pressure. Thus, the control cabinet is both cooled and purged with cool, clean air. Outside air is never allowed to enter the control panel.
