ACC designs and custom builds all of its industrial air conditioners specifically for harsh and severe conditions, whether intended for hazardous-duty, corrosive or simply very dusty, dirty and demanding environments. As a result, all units have several features to make them more reliable and durable than light-industrial and commercial-grade air conditioning units in dusty, hazardous, corrosive, humid, hot, cold, and other difficult, extreme environments:

  • To increase durability, we make our standard air conditioning units with cabinets of heavy-gauge 304L stainless steel, not the 22 gauge or lighter painted or galvanized steel found in most commercial-grade units. For extra harsh or corrosive environments, such as marine, we offer 316L stainless steel as an option.
  • To further resist acidic and caustic corrosion as well as that from salt and humidity, ACC protects its condensers and evaporators with a low-porosity (close to zero) epoxy coating (e-coating) electrostatically, first applied by immersion and then baked.
  • In order to make our units resist dust, sand and dirt, we use coils that allow the particles to pass between the fins without clogging them.  The evaporators and condensers have a maximum of 10 heavy-weight fins per inch, instead of the more common 16 to 22 light weight fins. ACC also uses ultra strong fan motors to enable them to move the dusty air all the way through the units.
  • To make its industrial air conditioners more resistant to electrical problems and easier to repair, ACC only uses mechanical controls, and not electronic. We protect the controls of normal location units inside a sealed NEMA 4X/IP56 box, and those of hazardous-location units in a NEMA 7 box.
  • ACC industrial air conditioners cool well at very high AND low ambient temperatures, because our clever, thoughtful designs enable our units to maintain their full rated cooling capacities up to 140°F (60°C) and down to 40°F (5°C) without modification (and down to -40°F/C as an option). Hence, ACC's air conditioners will cool when the ambient temperatures are too low for commercial grade air conditioners, but when it is still warm enough for a sealed building in the sun to heat up uncomfortably.
  • Designing our A-line units for high ambient conditions and rating them at 131°F (55°C), ensures that they will have extra cooling capacity at lower ambient temperatures. For instance, at 95°F/35°C, the standard temperature generally used for rating commercial-grade air conditioners, Aero's units have an actual capacity more than 10% greater than their rated capacities. We also design them such that they maintain their full rated cooling capacities at high altitudes.
  • To lengthen the life of the fan and blower motors, we use specially-made, totally-enclosed motor shafts, mounted on ball bearings and designed with Class F insulation.
  • ACC exclusively uses tough, backwardly-inclined blower wheels for the evaporators and the condensers. The blower wheels are made of an especially strong polyamide 6 plastic, reinforced with 30% glass fiber, or a special aluminum alloy— to make them quieter, stronger, more energy-efficient.  This combination of materials also makes them better able to handle heavy dust, dirt and sand loads in the air, and more corrosion-resistant than other types of wheels, particularly propeller types made of aluminum or with slinger wheels. The aluminum wheels we use are spark proof.
  • To make our industrial air conditioning units more durable and maintenance free, we use only resilient, low-maintenance, hermetically-sealed, scroll compressors (typically Copeland), instead of reciprocating, rotary or open-drive compressors.
  • We offer many different, custom electrical configurations, designed around our customers' requirements. We can also modify most of the designs to compensate for loss of capacity when operating the units at 50 Hz instead of 60 Hz.
  • To lower maintenance requirements and facilitate access, ACC mounts components on a reinforced 16-gauge stainless steel slide-in tray. We also include at least four refrigerant-access valves, a head-pressure control valve, an expansion valve, a shut-off valve on the receiver, a suction-line filter/dryer, a moisture indicator, a sight glass and a receiver.  A head-pressure control helps eliminate freezing up of the evaporator. We also protect the units against high and low refrigerant pressures and against overheating of the compressor and other motors.
  • To avoid corrosion on the condensers from the mixing of condensate water with the corrosive gases and particles in the air, ACC makes our units with dry condensers by using fans without slinger rings (which throw the condensation back onto the condensers in commercial-grade units).
  • Air filtration is provided by permanent polypropylene, electrostatic type filter elements secured strips to make them easy to remove and remount after cleaning with compressed air or water.
  • The units will meet the NEMA 4X and IP56 standards so that they will have long lives in corrosive and/or wet environments.
  • In those industrial air conditioning units where we install heat, ACC provides integral electrical-resistance heat with corrosion-resistant incoloy tubular elements (not light-weight wires) in capacities of 2.5KW on up to 10KW.  We also offer explosion-proof heat options.
  • ACC air conditioners are the "greenest" under harsh conditions. We specifically designs our units for operation and durability under extreme conditions, meaning they retain their energy efficiency in tough environments, not just in clean testing laboratories when new.
  • ACC uses environmentally-friendly refrigerants, typically R407C.
  • ACC makes all of our equipment in the United States of America (U.S.A.), at our Brooklyn, NY facility.
