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.

While our core focus has historically been providing industrial-grade HVAC systems to oil and gas facilities, we are always finding new ways to adapt to customer needs in other markets, including applying our knowledge to other markets including:

  • Cannabis
  • Modular and site-built data centers
  • Mining and other heavy industries
  • Power plants and energy storage
  • Water, wastewater, and sewage treatment facilities
  • Pulp/paper mills and steel foundries
  • And many more!

  • Customers choose to partner with;
