In chemical plants, oil refineries, paint shops, dry cleaning facilities, and other hazardous locations, heaters must be designed and manufactured with extra safety considerations in mind. These facilities are full of potential hazards like flammable dust, fibers, vapors, gases, and other substances—in both typical and emergency situations. Commercial and industrial explosion-proof electric unit heaters are made to the exacting standards required to operate safely in these extreme environments.

Hazardous area heaters are carefully sealed to prevent sparks. They are available in a wide range of models and sizes with ceiling, floor, or wall mount options. At NorthStock, we carry a wide selection of hazardous location heaters and other HVAC products from the industry's leading manufacturers, including BerkoChromaloxMarkelModineNorsemanQMark, and Ruffneck.
