EXAIR Cabinet Cooler Systems: Thermostats and Accessories

For most industrial enclosure cooling applications, a temperature of 95°F (35°C) is sufficient to be below the rated maximum operating temperature of the electrical components inside the cabinet. So, it is important to turn the cabinet cooler system on to keep the components cool, but at the same time we all know compressed air can be expensive if you over use it. A thermostat allows you to turn the cooler off when the enclosure is at or below the desired temperature, saving compressed air over continuous operation.

Cabinet Cooler

Here at EXAIR we are all about Engineered Solutions that will not only save you money but help your company “Go Green” by drastically lowering your energy costs. And when it comes to Cabinet Coolers, we have several options to control and manage the compressed air supply.

The most popular option is our Thermostat Control. EXAIR thermostats feature a bimetallic contact strip to open and close the electrical circuit in response to air temperatures.  These thermostats quickly respond to changes in air temperature and are specifically suited for their intended use.  Preset for 95°F (35°C), a suitable temperature for most electronic devices, these thermostats are fully adjustable for specific application needs. When thermostat closes it then turns the solenoid valve off turning the compressed air supply off. These thermostats are available in 12VAC, 240VAC and 24VDC.

Thermostat and ETC

In the event a more sophisticated thermostat control is needed, Electronic Temperature Control units can be implemented.  These standalone units utilize a thermocouple to determine internal cabinet temperatures which display onto a digital readout.  Push-button controls on the digital readout board allow for easy modification of the internal cabinet temperature set-point.  When the desired internal temperature is reached, the Cabinet Cooler system will turn off automatically.

One accessory that will give the flexibility to install EXAIRS cabinet cooler system is our Side Mount Kit. Sometimes there isn’t room above an electrical panel to fit the Cabinet Cooler, even though it takes just 5″ to 7.25″ of space above. In these cases, the Side Mount Kit is available to handle any of the Cabinet Cooler sizes and NEMA ratings. The NEMA 4 and 4X Cabinet Coolers must be mounted vertically for the unit to properly resist the ingress of liquids and maintain the integrity of the cabinet NEMA rating.

The Side Mount Kits install into a standard electrical knockout (1-1/2 NPS) for easy installation.

If you’re in need of a suitable cooling solution for an industrial enclosure, consider an EXAIR Cabinet Cooler systems.  They’re smaller than traditional AC units, faster to install, and require little-to-no-maintenance.  Feel free to contact an EXAIR Application Engineer with any questions, or fill out our online Cabinet Cooler Sizing Guide to have an Application Engineer contact you.
