EXAIR's Cabinet Coolers are ideal for dirty areas where contaminants might normally pass through small holes or conduits.
A NEMA 4 Cabinet Cooler cools the panel with 20°F air while keeping the inside dry.
EXAIR's Side Mount Kits for NEMA 12, 4 and 4X Cabinet Coolers offer convenient mounting to the side of an electrical enclosure.
How EXAIR Cabinet Coolers 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.

July 31, 2010 August 31, 2010 and we will include a FREE Model 7929 AC Sensor. It’s an ideal way to make sure there is power going to the electrical components in your cabinet. The tip of EXAIR’s AC Sensor glows bright red, and an audible alert sounds when voltage is present. Test circuit breakers, wall receptacles, switches, fuses, junction boxes and more. It’s even possible to locate electricity through insulation, making it ideal for finding breaks in wires!

What Is An EXAIR Cabinet Cooler®?
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. NEMA 12, 4, and 4X Cabinet Coolers that match the NEMA rating of the enclosure are available in many cooling capacities for large and small control panels.
Why EXAIR Cabinet Coolers?
The vortex tubes incorporated in the EXAIR Cabinet Coolers are constructed of stainless steel. The wear, corrosion and oxidation resistance of stainless steel assures long life and maintenance free operation. All Cabinet Coolers are UL and ULC Listed and CE compliant.
Selecting the Right Model
EXAIR Cabinet Coolers are available with or without thermostat control.
With thermostat: Model W4300 and W4800 series Cabinet Cooler Systems are thermostatically controlled. They save air by activating the cooler only when temperatures approach critical levels. The adjustable thermostat is factory set at 95°F. Systems with thermostat control are recommended where heat load fluctuates and continual purge is not required.
Without thermostat: Model W4200 and W4700 series Cabinet Cooler Systems are recommended when constant cooling and continuous purge are desired.
EXAIR Cabinet Coolers are available in a variety of cooling capacities. In most cases, 2,000 Btu/hr. is enough refrigeration to offset increased summertime heat load, regardless of panel size.
