Equipment Description
The Groen Convection Combo™ consists of a stainless steel cooking chamber, an air heating
compartment with heat exchange tubes and dual fans, a steam generator, and a control compartment
housing electrical components.
All major components of the Convection Combo are encased in a 16 gauge stainless steel cabinet. Glass
fiber insulation, 1 to 2 inches (2 to 5 cm) thick, lines the cabinet.
The oven has a double door with two large, tempered glass windows in each door. Oven viewing lights
are mounted between the inner and outer doors. Separate hinges allow easy access to the space
between the doors for window cleaning and light fixture maintenance. A condensate collection tray at the
bottom diverts condensate to the oven drain. An optional solid door is available. The solid door does not
provide viewing lights.
All operator controls are on the front panel, with the exception of the pilot ignition switch and main gas
shutoff valve, which are located behind the sliding access door on the front side of the unit.
Standard controls permit the Convection Combo to operate in four modes:
1. As a convection oven
2. As a self-contained, pressureless steamer
3. As a combination oven-steamer
4. With or without the meat probe operating
Cooking chamber capacity:
28 Steam table pans (12 x 20 x 2-1/2"), or
20 Bake pans (18 x 26"), or
40 Gastronorm pans (1/1)
All units are supplied on stainless steel legs.
Controls and monitoring displays for cooking time, operating mode, and temperature occupy the control
panel. The upper portion of the panel has a digital time readout and touch pads for setting the time. Below
the timer section are lights to indicate the status of the unit plus touch pads that select the mode of
operation and switch on the power. A digital readout shows the chosen temperature, which is selected
with a dial. Status of the pilot burners is indicated by the lights above the pilot ignition switch, located
behind the sliding door in the front of the unit.
An insulated, gas fired steam generator is mounted next to the oven. Steam enters the cooking chamber
through two connecting tubes at the top and bottom on the right side of the cavity.
The deliming solution is poured through a port just below the front control panel of the unit. Our unique
automatic cleaning system transfers de-liming solution to the steam generator.
The air heating space, containing the heat exchanger tubes and fans, is separated from the cooking
chamber by removable left, right, top, and bottom partitions.
The compartment containing the automatic controls and other electrical components is on the right-hand
side of the unit and is entered by removing the right outside panel or by opening the hinged panel in the
front.
A drain is located in the removable bottom of the cooking chamber. Fluids drain from this removable
bottom and from the permanent floor to the stainless steel drain pipe outside the oven. This drain pipe
includes a spray condenser, which suppresses any steam escaping from the chamber. The drain
assembly includes a built in vent with overflow protection.
The roll-in loading and unloading equipment for Combo SuperSystem 40 consists of the Model CCS
"Smart Cart" and the separate Model CRS rack. When the rack is engaged with the cart, a hand crank
raises the rack for transportation and lowers the rack to position it in the oven. The cart is disengaged
from the rack and removed before the oven door is closed. Design of the system allows the rack to be
easily held in and transferred between reach-in or walk-in refrigerators and freezers, blast chillers, and
holding cabinets.
