Last year was a big year for EXAIR’s Cabinet Cooling product line, in November we launched our first Hazardous Location Cabinet Coolers! EXAIR has always been a leading supplier in compressed air-based Cabinet Coolers, now we have expanded on that to work in the most high-risk conditions.
When a Hazardous Location Cabinet Cooler is used in conjunction with a purge system, they will keep electrical equipment at the desired operating temperature to protect and lengthen the lifetime of pricey controls and power supplies.
Electrical equipment can cause explosions in certain atmospheres. Equipment used in areas where explosive concentrations of dusts or vapors may exist must be equipped with special wiring and other electrical components for safety purposes. Hazardous (classified) locations such as these might exist in aircraft hangars, gasoline stations, paint-finishing locations or grain bins. EXAIR’s Hazardous Location Cabinet Coolers have been approved and tested by UL for use in the following areas:
Class I Div 1&2 – Groups A, B, C, and D
- Class I Areas refer to the presence of flammable gases or vapors in quantities sufficient to produce explosive or ignitable mixtures. Class I Div 1 will have ignitable concentrations of flammable gases present during the course of normal operations. This is level of approval is one that differentiates the EXAIR Hazardous Location Cabinet Coolers from much of the competition. Class 1 Div 2 areas will have flammable gasses or vapors present only in the event of an accident or during unusual operating conditions.
Class II Div 1&2 – Groups E, F, and G
- Class II areas are locations in which combustible dust may exist. The end user shall avoid installation of the device in a Class II environment where dust may be readily disturbed from the exhausts of the Hazardous Location Cabinet Cooler. Any dust formed in the vicinity of the cooler must be cleaned regularly.
- Class III areas are locations that will have ignitable fibers or flyings present. This is common within the textile industry.
The Cabinet Cooler also carries a temperature rating of T3C, meaning it cannot be installed near any materials that could auto-ignite at temperatures in excess of 320°F.
The Hazardous Location Cabinet Cooler is available in (8) different cooling capacities ranging from 1,000 Btu/hr – 5,600 Btu/hr. The Cabinet Cooler is the best solution for protecting your sensitive electronics from heat, dirt, and moisture. With Nema 4/4X systems available, the Hazardous Location Cabinet Coolers will keep the cabinet cool without compromising the integrity of the enclosure.
If you’ve got an electrical cabinet installed within a hazardous location, fill out the Cabinet Cooler Sizing Guide and allow an EXAIR Application Engineer to determine the most suitable model for you.
