The Groen DH is a floor-mounted, tilting, steam jacketed kettle with a thermostatically or
electronically controlled, self-contained, gas-heated steam source and appropriate controls,
mounted on a sturdy base. The Model DH is available in 20, 40, 60 or 80 gallon capacities.
The body of the DH Kettle is constructed of stainless steel, welded into one solid piece.
The kettle is furnished with a reinforced rim and a butterfly shaped pouring lip. It has a
steam jacket which is ASME shop inspected and registered with the national board for
working pressures up to 50 PSI. Kettle finish is 180 emery grit on the inside and bright
high buff polish on the outside.
The kettle is tilted with a hand crank to pour out its contents. Stainless steel panels
enclose the controls and the base. Four stainless steel tubular legs support the unit.
Bullet or flanged feet on each of the legs can be adjusted to level the kettle. Standard
DHT units include a two inch tangent draw-off valve.
The self-contained steam source is heated by propane or natural gas. Ignition is
electronic.
The kettle is charged at the factory with chemically pure water which contains rust
inhibitors. The steam source provides kettle temperatures of 150º to approximately
295ºF (65 to 150ºC). Unit controls include a thermostat or controller, pressure gauge,
safety valve, pressure limit control, low water cut-off, power switch and gas regulator
valve. The gas supply shuts off automatically when the kettle is tilted.
The unit must be specified for use with natural or propane gas. Service connections for
