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.

• DMC makes air conditioners for almost all hazardous groups and areas: Division 1, Zone 1, Division 2, and Zone 2

• From the outside, DMC's explosion-proof models look the same as our standard units - no unsightly explosion-proof box on the outside and generally no increase in size. Since DMC initially designed the units with the idea that many would be used in hazardous applications, we can make the adaptations inside the cabinets

• DMC uses compressors specifically recognized by Underwriters Laboratories (UL) as being suitable for use in the hazardous areas. There are no open compressors certified for hazardous locations

• DMC normally seals its hazardous-duty / explosion-proof / XP air conditioners in our factory to enable fast and easy installation

• DMC uses intrinsically safe control and monitoring systems when appropriate, EEx ib and EEx ia

• DMC's units have a low-temperature hazardous classification T3B (165°C) or T3C (160ºC), even when we include internal electrical-resistance heat.Under IEC / ATEX / CENELEC, the classification is T3

• DMC's blower wheels comply with the anti-spark standard AMCA C. As in all DMC units, we use only heavy-duty and durable, corrosion and dust-resistant, backwardly-inclined blower wheels, made of special polyamide 6 plastic reinforced with 30% glass fiber

• If heating is also required, DMC installs finned-tubular electrical-resistance heating elements inside its air conditioners with either 5KW or 10KW capacity and Temperature Code T3B

• Designs available for NEC Class I, Class II, and Class III, Group A, Group B, Group C, Group D, Group E, Group F, and Group GDivision 1 / Zone 1, Division 2 / Zone 2 and IEC Ex / ATEX / CENELEC EEX / CEC Group I, Group IIA, Group IIB, and Group IIC Zone 1, Zone 2, Zone 20, Zone 21, and Zone 22, Zone M1, Zone M2 Â (use either flame proof or increased safety construction)

• Configurations of air conditioners: Through-the-Wall (window), Roof-Mount and Ductless-Split
