FROM MINIMAL TO FULLY BUILT-TO-SPECIFICATION CUSTOM DESIGNS 

Custom Engineered Gas Fired Heating

GFW Series Custom Engineered Water/Water-Glycol Heat Transfer Systems offer Safe Reliable Performance in industrial gas-fired hot water systems with large heating capacity. 

Commonly used with satellite DIW Series Systems or EMW Series Systems, GFW Series systems provide a central water/water-glycol thermal fluid heating source for control of multiple, independent zones. 

Our engineering team will work with you to design a system based on your unique process or application. GFW Series systems typically include a Pump, Heater or Boiler, Cooling Circuit, Expansion Tank & Control Panel. Designs are capable of maximum operating temperatures up to 400°F and heating capacities up to 5.4 MM BTU/Hr. 

GFW Series Systems are constructed of threaded or all-welded Carbon Steel, are insulated with Non-Wicking Cellular Glass, Fiberglass, Rubber, or Mineral Wool Insulation, and assembled on a drip-proof, seal-welded plate-and-channel fluid containment base. 

HEAT offers four distinct levels of customization, ranging from minimal customization to fully built-to-specification designs. Each unique system undergoes a Factory Acceptance Test in accordance with HEAT standard practice prior to shipment.
