Nance International is the leader in the design and manufacturing of industrial-grade, standard-duty, severe-duty, hazardous-duty and explosion-resistant HVACR air conditioning systems.

Our team is equipped to custom design, build and install machinery, control panels or ducts that fit any specific needs. We can design and build HVAC units for elevated, outdoor ambient conditions, pressurization units and hazardous-duty units (NEC 500/505 Class 1, Division 1 & 2 units).

Nance’s highly-skilled and seasoned Fabrication Department works close with our Design and Project Management teams to produce custom HVACR systems for Commercial, Industrial, Maritime, Land/Offshore Drilling and Production applications. The systems we implement are built to satisfy customer specifications, adhering to the most stringent standards for hazardous/non-hazardous conditions. They can be either air-cooled or water-cooled with fresh or salt water.

More than 500 years of combined team experience goes into providing custom systems, which are built to code requirements (such as NEC, UL, CSA, ETL, ATEX) and undergo a complete factory acceptance test (FAT). No project is too large, too small or too complex.

Nance International is capable of providing equipment that meets nearly any industry standard, including Division 2 Hazardous Duty HVAC, Division 1 Explosion Proof HVAC, Zone 2 HVAC, ATEX HVAC, and other severe-duty applications.

Other applications include:

  •   Through the wall units
  •   Wall mounts
  •   Split systems
  •   Ductless split systems
  •   Heat Pumps
  •   Packaged units
  •   Chillers
  •   Cabinet coolers
  •   Chemical filtration
  •   Variable speed drive pressurization and purging per NFPA496
  •   Complete, skid mounted and turnkey packages

At Nance, we stand behind our custom-built, American-made equipment by offering a one-year warranty on products we produce. If a standard brand unit is modified by Nance, a one-year warranty will be placed on top of the manufacturer’s warranty.
