With everything that has been going on in the world these last few months, it seems crazy to think we’re knocking on the door of summer. The weather is warming up and it’s time to break out the swimsuits and flip flops (I’m sure our beach bodies are all ready after our quarantine diets and closed gyms…) One thing you can be ready for is the heat related shutdowns on your control panels. Using Vortex Tube technology, EXAIR’s Cabinet Cooler Systems provide a source of clean, cold air keeping your sensitive electronics safe. The newest addition to the Cabinet Cooler line, the Hazardous Location Cabinet Coolers, is designed to be used in areas that are exposed to flammable or combustible materials.
EXAIR’s Hazardous Location Cabinet Coolers are engineered for use with purged (not included) electrical enclosures. The HazLoc Cabinet Coolers are not purged and pressurized control systems and should not be relied upon nor used in place of a purged and pressurized controller. They are meant for use in conjunction with a purged and pressurized control system. These systems 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. For a comprehensive list and description of all of the various Classified areas, check out the UL website.
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.
