Equipment Description
OM/SM-TDB/7
The Groen TDB/7 is a table top, tilting, steam
jacketed kettle with a thermostatically controlled,
self-contained, electrically-heated steam supply
and appropriate controls, mounted on a sturdy
base. The Model TDB/7 is available in 20 or 40 quart capacity.
The body of the TDB/7 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 rated for working pressures up to 50 PSI.
Kettle finish is 180 emery grit on the inside and
bright semi-deluxe on the outside. A tilt handle
allows the operator to manually tilt the kettle
body in a controlled manner. Pouring height
accepts pans up to 4 inches high on a table top.
A built-in steam generator, sized for the kettle
capacity and heated by electricity, delivers steam
into the jacket. “Airless” operation of the steam
jacket permits uniform, efficient heating at
temperatures as low as 150°F and as high as
295°F. In addition to the adjustable thermostat
for operating control, the unit has a tilt cut-off
switch, low water cut-off, safety valve, and highlimit pressure switch as safety features. A
heating indicator light, pressure gauge, and sight
glass are provided for monitoring kettle
operation.
A single electrical connection is required for
installation. The unit may be ordered for use with
208/240 or 480 volt power. All kettles are wired
for three-phase operation. For single-phase
conversion, see the wiring diagrams in this
manual.
