Here in Ohio, we like to think we know a lot about the weather. Did you know there are more than 4 seasons? Heck, we have at least two Winters, and then a Pre-Summer, Spring, Summer, Heat is still coming – make it stop season, and Fall. Don’t forget the construction season where the lovely orange cones and barrels bloom on every major roadway, and then we also like to throw in brood weeks for the cicadas every now and then. Yeah, we get a full gambit of weather and the past week has brought out some heat. I know this isn’t just Ohio, we get calls from around the globe of atmospheric conditions that have caused issues within control panels. Some of these panels are in areas where the No Smoking sign is more than just a suggestion to better your health.
That’s right, there are areas in manufacturing facilities that are governed by the standard due to a variety of conditions resulting in what is known as Hazardous Locations. NFPA and UL have a list of standards breaking these down into separate Classes, Divisions, and Temperature Classes. If you want all the details, the NFPA code is around 908 pages, cover to cover. The Classified UL mark shown below is one way of knowing that a product has been tested to these stringent standards and is okay to use in clearly marked environments.
EXAIR offers Cabinet Cooler Systems that will meet these stringent standards and keep your enclosures cool in order to keep your production up and running. The top three tiers that we meet are:
- Class I Div 1, Groups A, B, C and D
- Class II Div 1, Groups E, F and G
- Class III
The HazLoc Cabinet Cooler Systems are available in 8 different cooling capacities from 1,000 Btu/hr to 5,600 Btu/hr. and are manufactured to work in conjunction with a purged and pressurized control system. As well as with or without thermostatic control.
If you would like help sizing the correct system for your electrical panels, feel free to use the link, or contact an Application Engineer to discuss the applications and get one sized while on the phone with us.
