High Temperature Water Heater

  • Hot water or fluid heating
  • 20 – 200 MMBTU/hr
  • Up to 2,300 psig
  • Forced Circulation
  • Available to less than 2 ppm NOx

The Cleaver-Brooks exclusive Max-Flow boiler incorporates a fluid-cooled  membrane wall construction for the furnace and heating coil enclosure, creating a highly efficient, shop-assembled package. 

Max-Flow Thermal Fluid Heater (TFH) and High Temperature Hot Water (HTHW) generators are available for most applications ranging from 20-200 MMBTU/hr. They incorporate a fluid-cooled membrane wall construction for the furnace and heating coil enclosure, creating a highly efficient, shop-assembled package. They can be fitted with a register burner or designed to recover heat from turbine exhaust and supplemented with a duct burner, up to 2,800˚F. This is a highly-efficient forced circulation design that will last for years to come.
