Equipment Description

The following dimensions apply to CE model HFP braising pans:

Model Width Depth Height Weight (Kg) Weight (lbs)
HFP/2E-3/2E-3 1245 mm 960 mm 1780 mm 241 530
HFP/2E-4/2E-4 1500 mm 960 mm 1780 mm 270 593

Groen Gas Heated Braising Pans provide a stainless steel pan equipped with patented heat transfer fins,
burner/combustion chamber, hand-operated tilting mechanism, thermostatic controls, and hinged cover. The
Braising Pan serves as braising unit, griddle, fry pan, oven, kettle, bain-marie, or food warmer and server, and it
can be adapted for use as a steamer.

The pan body is made from heavy-duty stainless steel welded into one solid piece, with a polished interior and
exterior. A pouring lip is welded to the front wall. The cooking surface is a stainless steel clad plate fitted with
welded heat transfer fins which assure uniform heat transfer over the entire surface. The gas burner/combustion
chamber supplies the heat.

An easily-operated worm and gear mechanism tilts the pan and provides precise control for pouring or dumping
the contents of the pan. This hand-wheel controlled mechanism is located in a stainless steel console to the right
of the pan body. To assist cleaning, the pan body can be tilted past the vertical position. When the pan is tilted, the
burners shut off automatically.The thermostat provides automatic control of cooking temperature. Operating 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 a condensate drip shield on the rear edge is standard
on the Braising Pan. A fully enclosed, spring type actuator counter-balances the cover to keep it in either the
opened or closed position. The cover opens to the back and is hinged to the frame, so it moves independently of
the pan body.

Options available with the listed models are:

1. Fill faucet with swing spout.

2. Caster mounting kit.

3. Fold-down work tray (pan support) mounted on left or right side. (Factory installed option)

4. 2” Tangent draw-off. (Factory installed option)

5. Model REJ Steamer Insert set.

6. Steamer pan Carrier.

7. Quick gas disconnect with restraining cable
