Equipment Description
Groen NHFP and NHFP(E) Gas Fired Braising
Pans provide a stainless steel pan equipped with
heat transfer fins, burner/combustion chamber,
power tilting mechanism, thermostatic controls,
and hinged cover. The Braising Pan serves as a
braising unit, griddle, fry pan, oven, kettle, bain
marie, or food warmer and server. It can also be
adapted for use as a steamer.
The pan body is constructed of heavy-duty
stainless steel welded into one solid piece, with a
polished interior and a semi-deluxe finish on the
exterior. A pouring lip is welded into the front
wall. The cooking surface is a stainless steel
clad plate fitted with welded heat transfer fins
that assure uniform heat transfer over the entire
surface. The gas burner/combustion chamber
supplies the heat.
The pan is tilted forward by an electrically
powered actuator mechanism. A three-position
switch on the front of the control console gives
the operator positive, smoothly operating control
of tilting. When the pan is tilted, the burners shut
off automatically.
The thermostat provides automatic control of
cooking temperature. The thermostat dial on the
front of the control console turns the heat on or
off and sets the pan temperature.
A vented, heavy gauge, one-piece, stainless
steel cover with rear condensate drip shield on
its underside is standard on the Braising Pan.
A fully enclosed, spring-type actuator
counterbalances the cover to keep it opened or
closed. The cover opens to the back and is
hinged to the frame, so that it moves
independently of the pan body.
Different ignition systems distinguish the basic
models. Model NHFP uses a thermopilecontrolled, standing pilot flame to light the main
burner. Model NHFP(E) ignites the main burner
directly with an electrically heated hot surface
igniter.
