Explosion proof Duct heaters – UL Listed for Hazardous Area category
Designed for use in hazardous areas with explosion-resistant cast aluminum terminal enclosure and redundant over temperature protection. Sized to fit the duct. Heavy wall, large diameter finned tubular elements, individually removable for servicing.
Tubular and finned designs can provide outlet air temperatures up to 650C (1200F) for industrial heating applications. Applications include petrochemical plants, aircraft hangars, fueling areas, oil drilling rigs, sewage treatment plants, pipeline pumping stations, paint spray booths, storage areas for flammable products, labs or testing areas.
Our explosion proof duct heaters is the solution to the problem of heating equipment and products where Class 1, Division 1, Groups B, C, D hazardous gases or vapors exist.
Class I means that ignitable concentrations of flammable gases, vapors, or airborne liquids can exist under normal operating conditions.
Div 1” means that these ignitable elements can exist during normal operations,
Group B : Hydrogen, butadiene, ethylene oxide, propylene oxide, and acrolein are popular examples of this group.
Group C: Carbon monoxide, ether, hydrogen sulfide, morphline, cyclopropane, ethyl, isoprene, acetaldhyde and ethylene etc.
Group D consists of all other flammable gases, vapors & liquids. Gasoline, acetone, ammonia, and benzene are common examples.
