Cabinet Coolers are a low cost, reliable way to cool and purge electronic control panels. They provide air conditioning for the electrical enclosures, eliminating electronic control downtime due to heat, dirt and moisture! These panel cooling systems for enclosures incorporate a vortex tube to produce cold air from compressed air – with no moving parts.
These air coolers operate by using a vortex tube to cool the compressed air. A vortex tube accelerates the inlet compressed air (A) so that it rotates rapidly. As it expands and rotates up the tube it heats and is pushed to the side of the tube (B) this draws heat energy from the air in centre of the vortex tube (C) which is displaced downwards. In this way the cool and hot air are separated. The hot air then vents form the system through holes (D). A further hot air vent (E) allows displaced hot air from within the cabinet to vent. The cool air generated in the vortex chamber is then distributed within the cabinet through a tube with holes (F)(G)(H) and (I). These holes can be strategically drilled / positioned so that cool air blast directly hot spots such as CPUs. The cool air, once within the cabinet, will mix will and cool the hot air displacing it and forcing the warm air through vent (E).

Wattage
Each vortex tube is rated to a specific wattage this represents the overall cooling capacity of the tube. The cooling power ranges from 85 to 849 watts with six gradations.
Nema/IP rating
The American Nema standard and its European IP rating equivalent are a measure of how protected a system is against water/ dust contamination. The rating will determine under what conditions the equipment can operate effectively.
The vortex cabinet coolers come in three different models / Nema/IP ratings.
EXAIR NEMA 4 (IP66) Cabinet Coolers
NEMA 4 (IP66) Cabinet Coolers (dust-tight, oil-tight, splash resistant, indoor/outdoor service) incorporate a low pressure relief valve for both the vortex tube and cabinet air exhaust. This valve closes and seals when the cooler is not operating to maintain the NEMA integrity of the electronic enclosure. NEMA 4 (IP66) Cabinet Coolers are available in many cooling capacities for large and small control panels. Unlike an expensive, freon-based air conditioner, EXAIR Cabinet Coolers incorporate a vortex tube to produce cold air from compressed air – with no moving parts. They can be installed in minutes through a standard electrical knockout. NEMA 4 Cabinet Cooler® Systems are available with a thermostat control or as a continuous operation system. Each of these systems include a water-dirt filter separator to prevent water condensate and dirt from entering your enclosure and a cold air distribution kit used to direct the air for circulation or on to hot spots. All Cabinet Coolers are UL Listed and CE Compliant. They are a low cost, reliable way of cooling and purging electronic control panels.
