Industrial Air Conditioning Systems

Aero Conditioner Co. (ACC) designs its industrial air conditioning systems for most hazardous classes, groups, divisions and zones. We build all of our hazardous-area (explosion-proof) equipment to tolerate and perform well in the same severe conditions as do our regular harsh-duty units: dusty, dirty, corrosive, hot (even very cold environments), high altitude, super humid and otherwise extreme-pressure to assure long life under severe conditions.


  • ACC builds industrial air conditioning systems for virtuall all hazardous groups and areas: Division 1, Zone 1, Division 2, and Zone 2, as well as Zone 20, Zone 21, and Zone 22
  • Viewed externally, our "explosion-proof" units have the same appearance as our standard units - no clunky explosion-proof box on the outside and generally no material increase in size. Since we initially designed the HVAC units with the idea that many would be used in very hazardous applications, we make the adaptations inside the stainless steel (304L and 316L configurations) cabinets
  • Aero uses industrial air conditioning compressors specifically recognized by Underwriters Laboratories (UL) as being suitable for use in the hazardous areas. We offer open compressors certified for hazardous locations
  • We normally seal our explosion-proof (XP) air conditioners in our factory to enable fast and easy installation
  • We also use intrinsically safe control and monitoring systems when appropriate, to enable remote installation of controls
  • Our industrial 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
  • All of our blower wheels comply with the anti-spark standard AMCA C. As in all ACC units, we use only heavy-duty, strong, corrosion and dust-resistant, backwardly-inclined blower wheels, made of special polyamide 6 plastic reinforced with 30% glass fiber or wheels mode of a special alloy of magnesium and aluminum
  • If heating is required, we use finned-tubular electrical-resistance heating elements inside our units with anywhere from 1.5KW to 10KW capacity and Temperature Code T3B or T3C
  • 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 G Division 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 (use either flame proof or increased safety construction)
  • The configurations of  our industrial air conditioner units available are: Through-the-Wall (window), Roof-Mount, Ductless-Split, vertical (Wall Hung), Interior (Container), and Mobile (Spot)

Common applications for our harsh duty, industrial air conditioning units:

  • Gases - Flammable and Explosive
  • Coal, Coke and other related Dusts
  • Combustible Metal Dusts such as Magnesium and Aluminum
  • Textile Fibers and Flyings
  • Other Hazardous Dusts such Grain, Flour, Wood, Plastic and Chemicals
