Equipment Description
The Groen DH is a floor-mounted, tilting, steam jacketed kettle with a thermostatically controlled, self-contained, gas-heated steam source and appropriate controls, mounted on a sturdy base. The Model DH is available in 20, 40 or 60 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 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, 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 gas and electricity are required. Standard power supply is 115 Volt. Alternate voltages (208V or 240V) are available.
