Steam or Boiler
Hot Water HWG
Generator Systems
Designed for utilizing steam or high
temperature boiler water as an
energy source
HOT WATER GENERATORS
These skid-mounted water heater systems are completely assembled and
packaged for use. All components are sized, piped and checked at the factory
before shipment. HWG systems save labor and time, requiring only connection
to heat source.
Packages include pressure regulators, temperature regulators, steamtraps,
strainers and other custom items such as standard or optional features.
Tank and heat exchanger capacities will closely match those now available,
80 through 12,500 gallons and 0.9 through 214 square feet of heat transfer.
