EXAIR‘s Cabinet Coolers are a low-cost and reliable way to cool and purge your electrical panels. They incorporate our Vortex Tubes to produce cold air from compressed air. With no moving parts, our Cabinet Coolers can run maintenance free for many years.
When selecting which Cabinet Cooler is right for your application, there are a few things for you to consider:
First, is your cabinet in a hazardous location? We have HazLoc Cabinet Cooler models that are rated for UL Classified areas, including Class I Div 1, Groups A, B, C, and D; Class II Div 1, Groups E, F, and G; and Class III; as well as ATEX rated units that are approved for use in Zones 2 and 22. All of our hazardous location Cabinet Cooler Systems need to be used in conjunction with a purged and pressurized control system.
After this you will need to determine what NEMA integrity your enclosure requires.
We have NEMA 12(IP54) models, which are dust and oil tight. These are ideal for most industrial environments where no liquids or corrosives are present.
Our NEMA 4(IP66) options can be used inside and outside, and are splash resistant as well as dust tight and oil tight. The low-pressure relief valve will ensure the integrity of the NEMA 4 enclosure is maintained.
Finally, our NEMA 4X(IP66) option offers all the same protection as the NEMA 4X, but is constructed of stainless steel for food service and corrosive environments.
Next, you need to decide if you need continuous operation or thermostat control. The thermostat control systems are the most efficient way to operate a Cabinet Cooler. They save on compressed air by only activating the cooler only when the internal temperatures approach critical levels. The standard thermostat control systems include an adjustable thermostat factory set at 95°F. We also have our Electronic Temperature Control (ETC), which allows for precise temperature control that can be adjusted with the touch of a button.
Finally, you will need to calculate the heat load to determine the cooling capacity. We have a calculator on our website that can help with this. However, if you speak to any of our Application Engineers, we can perform these calculations for you. If you would like to discuss your Cabinet Cooler application, feel free to give us a call!
