Our expertise

One of the greatest advantages of buying from Specific Systems is the knowledge we have gained in meeting and exceeding NFPA requirements. Because we specialize in manufacturing units for petroleum processing facilities, many of our designs include explosion-proof housings and components. An adapted InPac or AirPak unit would easily fill requirements at military refueling posts or other petroleum related applications.

Specific Systems is the company with the knowledge, experience, and manufacturing capacity to complete your order in an efficient manner, and the products on the following pages are certain to meet your needs. If your application requires a custom unit, please call us, and one of our engineers will be ready to help you.

We combine our expertise in HVAC with our knowledge of hazardous areas to provide packaged solutions to highly corrosive and hazardous (up to Class I, Division 1, Groups C and D) locations. Our InPac line is available in several formats to fit the needs of individual applications:

Vertical, through-the-wall (standard)
Horizontal, roof-mount
Split condenser/evaporator
Pad mount

Our AirPak wall-mount industrial HVAC systems are available in capacities from 5–20 tons with a variety of optional equipment.

Specific Systems is a privately held company, and our focus is on our customers—not shareholders. We ensure a level of service after the sale that is second-to-none.
