CABINET CONSTRUCTION Heavy-duty construction includes stainless front (doors and grilles). Exterior sides are steel with gray finish. Exterior top and back are galvanized steel. Interior bottom is stainless. Interior of cabinet is constructed of white coated steel walls. Adjustable epoxy coated steel wire shelves are standard (3 per section). Foamed-in-place CFC and HCFC-free polyurethane insulation enhances the structural strength of the cabinet and helps increase energy efficiency. Doors attach to cabinet on cam-lift hinges. Hinges permit doors to stay open at 120° and gravity self-close. Snap-in magnetic gaskets for a positive seal are standard. Gaskets are easily removable for cleaning. Three-inch heavy-duty casters included, two with brakes standard. REFRIGERATION Balanced refrigeration system is located at bottom of cabinet. System uses R404A refrigerant, which is CFC and HCFC-free for compliance with environmental safety concerns. Defrosting is accomplished with electronic heaters. Defrost is time initiated, temperature terminated. A time termination is provided as a back up fail-safe. Evaporator fans are delayed from restarting until evaporator coil is adequately chilled down. Operation of compressor is governed by temperature control inside top of cabinet. Enhanced digital control is located outside top of cabinet. Control includes "Door Open Indicator" and displays internal cabinet temperature.
