Equipment Description
Groen Models HH/4 and HH/4E steam kettles
are stainless steel, floor mounted 40 gallon
kettles with a self-contained steam source
heated by gas. A closed steam jacket covers the
lower b of the kettle. Heat from gas flames boils
water in the jacket to produce steam under
pressure. To ignite the flames, Model HH/4 has a
continuously burning pilot flame, called the
standing pilot, and Model HH/4E has electronic
spark ignition.
The kettles are of the stationary (nontilting) type.
Liquids can be removed from the kettle through
the tangent draw-off valve (a “product faucet”) at
the front of the kettle.
All exposed surfaces are stainless steel. An
insulated canopy protects the kettle body, and a
housing encloses all the controls. A one piece
dome cover is hinged to the kettle.
Three tubular legs support the unit. Bullet feet on
the legs can be adjusted to level the kettle.
Controls used by the operator include the
ON/OFF switch, which controls electric power for
the unit, and the thermostat, which sets the
cooking temperature.
Instruments are provided to show what is
happening inside the unit:
• Pressure Limit Switch: Turns the main burner
off when steam in the jacket reaches its
highest operating pressure.
• Low-water cutoff: Turns off the burner if water
level in the jacket gets too low for safe
operation.
• Safety valve: Releases steam if jacket
pressure gets too high
The 40 gallon kettle body is welded into one
piece and furnished with a rim reinforced by a
rectangular bar. The unit is ASME shop
inspected and registered with the National Board
for working pressures up to 30 PSI.
The standard 2 inch tangent draw-off has a
removable strainer with ¼ inch holes which keep
pieces of product that are too large from going
down into the draw-off.
The jacket is filled at the factory with water
containing rust inhibitors. The kettle can operate
at steam pressures up to 30 PSI, which provide
kettle temperatures of 150 to approximately
270°F (56 to 132ºC). This temperature range
allows the operator to use the kettle for warming,
simmering, boiling, or braising.
Optional equipment for the HH/4 kettles includes:
• Water gauge glass: shows the level of water
within the steam jacket
• Pressure/vacuum gauge: shows the steam
pressure and if there is air in the jacket
• Indicator lamp: Lights when the kettle is being
heated
Automatic controls within the unit:
• Gas Pressure Regulator: Adjusts gas
pressure up to 14" W.C.
• Three inch draw-off valve
• c” perforated or solid disc strainer
• Basket inserts (TRI-BC)
• Water fill faucets
• Automatic water filler
• Kettle brush kit
• 316 stainless steel liner
