Cabinet Coolers

Exair’s cabinet coolers stop electronic control downtime due to heat, dirt, and moisture. They are designed to cool and purge NEMA 4, 4X and 12 electronic control panels. Newer models are available for NEMA 4 and 4X hazardous locations.


Exair’s cabinet coolers incorporate a vortex tube to produce cold air from compressed air and are available with or without a thermostat. Continuous operation models are recommended when constant cooling and a constant positive purge are desirable. Thermostatic models are recommended when heat load fluctuates and cooling is not always needed.

First determine the type of enclosure you have, then decide if continuous operation or thermostat control is needed. The next step is to calculate the heat load for your enclosure. Models are available from 275 Btuh (69 Kcal/hr) to 5,600 Btuh (1,411 Kcal/hr). Cabinet coolers install in minutes, are quiet, stabilize enclosure temperature, and have no moving parts – which makes them maintenance free.
