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.
