EXAIR NEMA 4 Cabinet Cooler® Systems, Continuous Operations (No Filter)

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 integrity of a NEMA 4 enclosure. NEMA 4 continuous Cabinet Cooler® Systems are recommended when constant cooling and constant positive purge are desirable. Systems for continuous operation include a Cabinet Cooler and cold air distribution kit. NEMA 4 (IP66) Cabinet Coolers are available in many cooling capacities for large and small control panels. All Cabinet Coolers are UL Listed and CE compliant. They are a low cost, reliable way to cool and purge electronic control panels. EXAIR Cabinet Coolers incorporate a vortex tube to produce cold air from compressed air - with no moving parts. The compact Cabinet Cooler can be installed in minutes through a standard electrical knockout.

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.

Cabinet Cooler Standards and Certifications

EXAIR's Cabinet Cooler Systems comply with OSHA's Safety Requirements, the EU General Product Safety Directive (2001/95/EC) and meet the noise limitation requirements of the EU Machinery Directive (2006/42/EC). In addition, Cabinet Cooler Systems are Listed to applicable UL Standards and requirements by Underwriters' Laboratories. All sound level measurements are taken at 3 feet away.
