Exair Cabinet Cooler Systems

 Exair(USA)  offers a variety of Cabinet Cooler Systems designed to keep electrical enclosures cool by using compressed air to provide a low-cost and reliable solution. Here are some types of Cabinet Coolers that Exair offers:

  1. NEMA 12 Cabinet Coolers: Designed for industrial environments where no liquids or corrosives are present, these coolers provide a reliable and low-cost way to cool electrical enclosures. They are dust-tight and oil-tight


  1. NEMA 4 Cabinet Coolers: These are used in wet, damp, and/or corrosive environments. They offer the same cooling power as the NEMA 12 models but are more robust against moisture and contaminants. They are 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.


  2. NEMA 4X Cabinet Coolers: Offer the same protection as NEMA 4, but ideal for corrosive or washdown environments, such as food processing  and corrosive environments. They are made from stainless steel to resist corrosion.

  3. High Temperature Cabinet Coolers: For ambient temperatures of 125° to 200°F (52° to 93°C) are available. Internal components can withstand high temperatures (like those near furnaces, ovens, etc.).They are suitable for locations with high ambient heat.


  4. Non-Hazardous Purge Cabinet Coolers: are ideal for dirty areas where contaminants might normally pass through small holes or conduits. Under normal conditions, the NHP Cabinet Cooler Systems provide a slight positive pressure in the enclosure by passing 1 SCFM (28 SLPM) of air through the cooler, when the solenoid valve is in the closed position. When the thermostat detects high temperature, it energizes the solenoid valve to pass full line pressure and volume of compressed air to the Cabinet Cooler, giving it full cooling capability


  5. Hazardous Location Cabinet Coolers: Hazardous Location NEMA 4 (IP66) Cabinet Coolers are engineered and approved for use upon purged electrical enclosures found within classified areas. The areas approved are Class I Div 1, Groups A, B, C and D; Class II Div 1 Groups E, F and G; and Class III. These HazLoc Cabinet Cooler Systems have been tested by UL and meet the stringent UL requirements for these areas. Cabinet Cooler systems are a low cost and reliable way to cool purged electric control panels found within these environments.


  6. Cabinet Coolers - ATEX: ATEX Cabinet Cooler Systems are engineered and approved for use upon purged electrical enclosures (not included) found within ATEX zoned areas. The areas approved are Zone 2 and 22.


These coolers are available in different cooling capacities to suit various application needs, ranging from small control panels to large enclosures with significant heat loads. Please fill the Sizing Guide and send to us to recommend the perfect model for your panel/enclosure.
