Specific Systems

Specific Systems® is the leading manufacturer of third-party certified Explosion Proof HVAC, Explosion Proof Air Conditioning, Severe Duty HVAC and ATEX HVAC Systems for the petrochemical, telecommunications, military, and other difficult environments. Since 1974, Specific Systems® has shipped thousands of special purpose air-conditioning, heating, ventilating and pressurization systems with a commitment to reliability, service and design excellence. Specific Systems® specializes in building the best severe duty and explosion proof HVAC in the world.

We offer several HVAC product lines, each targeted to a slightly different market. All available InPac* and AirPak units feature our unique dual refrigeration circuit system, which gives true redundancy and allows the unit to function at half of maximum capacity in the event one circuit fails. The popular InPac line features a through-the-wall design, which allows all maintenance on the unit to be completed from inside the conditioned area. This is an advantage in the hazardous (classified) environments in which InPac units are placed.

Specific Systems® standard heater systems are available on all units in standard heating capacities from 5kW to 60kW, depending on unit size. All capacities 10kW and greater are installed with 2-stage heating, allowing the unit to draw only the power needed to compensate for given conditions. Finned-tube heat offers some advantages over standard wire element heat, and is required in some applications. At Specific Systems®, we manufacture HVAC specifically designed for the modular building industry.

We are passionate about meeting our customers' needs and forging long-lasting relationships based on mutual respect. We work as a team to provide innovative solutions and premier HVAC systems engineered for rugged environments.
