Air Conditioners
for Hazardous / Explosion-Proof / Flameproof / Rugged Conditions

DMC manufacturers its heavy-weight industrial hazardous-duty air conditioners and ventilation systems for most hazardous classes, groups, divisions and zones. DMC builds all hazardous-area (explosion-proof) equipment to resist the same severe conditions as do its regular harsh-duty units: corrosive, dusty, hot (and cold), high altitiude, humid, vibrating and otherwise extreme-pressure long lives under tough conditions. DMC builds only industrial units--we do not modify lightweight residential or commercial units. All DMC's hazardous-duty products meet the same tough, extreme-duty standards as regular DMC equipment to ensure that they last longer and tolerate severe corrosion, dust, heat / cold, humidity, marine environments, and vibration better than modified lightweight equipment.

Applications for DMC harsh and hazardous duty units:

Gases - Flammable and Explosive

Coal, Coke and related Dusts
