220 Series Explosion-Proof Duct Heaters
CSA Approved for Class I, Division 2 locations where a hazardous gas is occasionally present. Ignition temperatures as low as 392°F (200°C) for ducts up to 240″ (610 cm) wide by 120″ (305 cm) high. Ratings up to 1000 kW, 600 volts.
Standard Features
Hazardous locations are those areas where a potential for explosion and fire exists due to the presence of flammable gases, vapors, pulverized dusts or ignitable fibers in the atmosphere. Hazardous locations are created from the normal processing of volatile chemicals, gases, coal, grains, etc., or from the accidental failure of storage systems for these materials.
Open flames are not permitted in these locations. The use of electric heating equipment is permitted with two major restrictions: 1) The surface temperature of the equipment cannot exceed the ignition temperature of the hazardous atmosphere and 2) all arc and spark producing devices must be isolated from the atmosphere in an appropriate enclosure.
Both people and equipment in hazardous locations can be heated safely and economically with electric heat. Electric heating is typically much less expensive to install and maintain than comparable remote oil or gas fired heating systems.
