AVAILABLE HEATER DESIGNS
Helical Coil HELICAL COIL - 2 PASS DESIGN
This horizontal two pass, helical coil offers a simple, low cost, low maintenance, design for a thermal fluid heater. The heater chamber is based on a horizontal center fired burner utilizing radiant heat from the flame on the coil for the first pass. Hot combustion gases turn back along the outer side of the coil for convective heating on the second pass. Typical heater efficiency is 80% LHV. Capacities available for the GFOH thermal fluid heater range from 700,000 to 18 million Btu/hr.
2 Pass Heater Design
Dual Coil DUAL COIL - 3 PASS DESIGN
This three pass, helical coil design offers very high thermal efficiencies for a compact thermal fluid heater. The heater chamber is based on a vertical down fired burner, utilizing radiant heating on the first pass and convective heating on the second and third passes. The large chamber diameter and increased surface area of the dual coil ensure long life of the thermal fluid. Typical heater efficiency is 90% LHV. Capacities available for the GFOD thermal fluid heater range from 500,000 to 20 million Btu/hr.
3 Pass Helical Coil Design
Isolated Coil Design ISOLATED COIL DESIGN
This multi-pass, nested coil offers high thermal efficiencies and extended coil life for a compact thermal fluid heater. The isolated combustion chamber eliminates impingement damage to the coil. Forced draft gases exiting the combustion chamber provide both radiant and convective heating in the coil chamber. Combustion air is preheated for increased fuel efficiency. Typical heater efficiency to 85% LHV. Capacities available for the GFOI thermal fluid heater range from 2.5 to 20 million Btu/hr.
Multi Pass Nested Coil
Multi Pass Water Coil Heater Design MULTI-PASS WATER COIL DESIGN
This multi-pass, staggered coil design offers high thermal efficiencies for a direct fired hot water boiler. The low pressure upshot burners provide both radiant and convective heating to the tube bundle. Capacities available for the GFW design range from 240,000 to 5.4 million Btu/hr.
Staggered Coil Design
