EXAIR Cabinet Coolers

Supplier: HybraLec Industries

Stop electronic control downtime due to heat, dirt and moisture!


It happens when you least expect it. High temperatures can cook the electronics that control your machines, resulting in erroneous readings, trip-outs or fried circuit boards. Cooling the electrical cabinet can eliminate these problems.

  • EXAIR's compressed air operated Cabinet Coolers are the low cost solution.
  • NEMA 12, 4 and 4X model Cabinet Coolers are available that are very compact and mount in just minutes through an ordinary electrical knockout.
  • Thermostat control limits compressed air use by operating the Cabinet Cooler only when the temperature inside the enclosure reaches critical levels.
  • The Cabinet Coolers have no moving parts to wear out and do not require constant monitoring.

Applications of EXAIR Cabinet Coolers:

  • Food service equipment
  • Cool laser housings
  • Computer cabinets
  • Modular control centres
  • Relay panels
  • Motor control centres
  • Line control cabinets
  • Programmable controllers

How does it work?

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.

Environmental Considerations

NEMA 12 (IP52) - dust-tight, oil-tight

NEMA 4 (IP56) - dust-tight, oil-tight, splash resistant, indoor/outdoor service

NEMA 4X (IP56) - same as NEMA 4 but are constructed of stainless steel for food service and corrosive environments.

Dual cooling system for large enclosures now available.  The high cooling capacity up to 5,600 Btu/hr. is ideal for large electrical enclosures and high heat loads.

Side Mounting for Cabinet Coolers. Exair's Side Mount Kits offer convenient mounting to the side of an electrical enclosure for applications where top mounting is not possible due to limited space or obstructions above the enclosure.

316SS Cabinet Coolers Resist Heat and Corrosion.  The wear, corrosion, and oxidation resistance of 316 stainless steel assures long life and maintenance free operation.
