Vortex cooling techniques provide an effective solution to the problem of thermal protection of electrical enclosures, keeping internal temperatures down and helping to reduce critical control failures.
A vortex cooling enclosure cooler uses a vortex tube to convert a filtered, compressed air supply into refrigerated air without the use of electricity, ammonia or other refrigerants. The vortex tube creates cold air and hot air by forcing compressed air through a generation chamber which spins the air centrifugally along the inner walls of the tube at a high rate of speed (1,000,000 rpm) toward the control valve.
Vortex coolers are available from ITW Vortec for NEMA 4, 4X and 12 rated enclosures and, with a minor modification, are well suited for use in hazardous environments as well. At a fraction of the cost of air conditioners, vortex coolers also offer ease of installation, compact size and very low maintenance when compared to a refrigerant-based air conditioning unit.
