steel construction. Heavy-duty doors (specify glass or
solid) are field adjustable, reversible and close with gentle
push or slam.
Patented tube fired heat exchanger surrounds each
product cavity. Narrow vertical steam generator is located
behind each product cavity. Heavy insulation surrounds
each cavity/combustion chamber on all sides.
Stainless steel support stand with front mounted steam
generator deliming port standard.
Finish
Cabinet exterior and doors shall be finished to uniform
#3 finish. Cavities, rack supports and pan racks shall be
polished stainless steel. Control panels shall be smudge
resistant matte finish film ensuring maximum ease in
cleaning and maintaining an attractive appearance.
CSA Design Certified
Steamer shall be CSA (formerly AGA) design certified to
ANSI Z83.11”.
Sanitation
Unit shall be designed and constructed to meet NSF
requirements, and be NSF listed. Cooking chamber top,
bottom and side panels with pan supports and chamber
doors are removable for easy cleaning. Programmed
cavity cleaning and steam generator deliming cycle, with
easy access table mounted deliming port are standard.
Controls
Unit shall have all solid state controls to include digital
timer with LED readout, power on/off and mode selection
touch pad switches and knob set temperature control
with continuous LED digital readout. Temperature can be
displayed in either F or C. If the “Cook Probe Hold” option
is ordered a low range solid state temperature control with
continuous LED readout provided. If Programmable option
is ordered up to 50 recipes can be entered and used
for cooking. The “Cook Hold Probe” and Programmable
options provide a temperature probe to allow cooking to
a selected core temperature. Hidden door interlock switch
cuts power to fan and oven/steamer elements when door
is opened. Wait, Ready and Hot indicator lights provide
status in each cooking mode. Clean and Service lights
indicate when the unit needs attention. Solid state circuitry
has self diagnostic program and pre-programmed clean
cycle to assist in trouble shooting and daily cleaning.
Performance Features
ON switch activates power to circuitry. When Oven Mode
is selected, gas burners ignite and side mounted blower
activates, to provide oven temperatures up to 575˚F. When
Steam Mode is selected, steam generator fills with water
and burner assembly ignites, to generate pressureless
steam at 212˚F. When Combo Mode is selected, oven and
steam generator burner assemblies provide a continuous
superheated steam environment.
