Speciﬁcation Line

Model numbers starting with the letters “SS” have a stainless

steel exterior and interior. Model numbers starting with the letters

“SA” have an aluminum interior and a stainless steel exterior.

Model numbers starting with the letters “SM” have an aluminum

interior and exterior with a stainless steel front and shroud. Door

gaskets are magnetic and mount to the door, snapping in place

and are removable without tools. Keyed door lock is mounted

in the door next to the handle.

Doors can be removed from the cabinet without the use of

tools. Each door has two edge mount, self-closing, cam lift

style hinges.

Refrigeration System

All components are mounted to the exterior cabinet ceiling,

outside the food zone and are assembled as one-piece and can be

removed as one-piece. Environmentally friendly R404A refrigerant

is used. The system has the capability of maintaining between 27°F

and 40°F (-3°C and 4°C) in heavy use food service operations.

Refrigerant is metered using a highly responsive thermostatic

expansion valve. Systems are controlled using Delﬁeld’s ETC1

Electronic Temperature Control. It provides improved pull down

times, reducing compressor cycling and longer compressor life

with lower energy consumption. Control system uses adaptive

defrost to assure evaporator coil is free of ice and operating at

optimum efﬁciency. Evaporator condensate is eliminated using

an energy efﬁcient hot gas system.

Freezer Refrigeration System

All components are mounted to the exterior cabinet ceiling, outside

the food zone and are assembled as one-piece and can be removed

as one-piece. Environmentally friendly R404A refrigerant is used.

The system has the capability of maintaining between -5°F and

0°F (-21°C and -18°C) in heavy use food service operations.

Refrigerant is metered using a highly responsive thermostatic

expansion valve. System is controlled using Delﬁeld’s ETC1

Electronic Temperature Control, which provides improved pull

down times, reducing compressor cycling and longer compressor

life with lower energy consumption. Control system uses adaptive

defrost to assure evaporator coil is free of ice and operating at

optimum efﬁciency. Evaporator condensate is eliminated using

an energy efﬁcient hot gas system.

Heating System

Heating system cabinets are designed to maintain temperatures

between 120°F and 200°F (49°C and 93°C). Heating elements

are helical shaped, with tubular ﬁns. A circulating fan provides

uniform airﬂow in the cabinet. The entire heating system is

mounted to the exterior of the cabinet ceiling, outside the food

zone. It is assembled as one piece and can be removed as one

piece. An adjustable electronic thermostat controls temperature.

The system ON/OFF switch is located on the front exterior of

the cabinet.

Dual Temperature Refrigeration/Freezer

Each compartment has its own separate refrigeration system.

Condensing units are located on top of the cabinet, outside

the food zone, behind the upper shroud. Evaporator coils are

located inside the cabinet mounted to the interior ceiling of each

compartment. Defrost is automatic. Condensate travels down

a tube in the cabinet sidewall to a receptacle mounted to the

exterior bottom of the cabinet where it evaporates with the aid of

an electric heater. Each compartment’s temperature is individually

monitored and controlled with Delﬁeld's ETC1 Electronic

Temperature Control. Two exterior digital thermometers monitor

temperature. Refrigerator compartment maintains temperature

between 33°F and 41°F (1°C and 5°C). Freezer compartment

maintains temperature between -5°F and +5°F (-21°C and -15°C).

Refrigerant is metered using a highly responsive thermostatic

expansion valve.

Ready Thaw

Ready Thaw is designed to thaw frozen food under controlled

temperature conditions in approximately 18 hours and then

hold it at normal refrigerator temperatures. This unit uses a

standard refrigeration system mounted to the exterior cabinet

ceiling coupled with a heater and fan mounted in the center of

the refrigerated cabinet. The unit will operate as a standard

refrigerator and maintain a temperature of between 33°F and

41°F (1°C and 5°C)until a quantity of frozen product drops the

temperature below 20°F (7°C). The control will then automatically

cycle the heater and fan to begin the thaw process. After the

product is thawed, the electronic control will turn off the heater

and fan and return to standard refrigeration operation.
