Delfield SARRT3-S Leaflet

Exterior: SS and SA models shall have corrosion resistant stainless 

steel exterior cabinet sides, front and shroud. SM models shall have 

corrosion resistant aluminum on exterior cabinet sides and will have 

stainless front and shroud. All units shall have the upper shroud 

hinged with a gas assist stay open feature to provide easy access to 

the refrigeration system.

Interior: Cabinet interior shall be corrosion resistant stainless steel 

(SS models) or heavy gauge aluminum (SA and SM models). Bottom 

and top surfaces shall be die stamped to provide radius corners 

and recessed floor. Mounted to the interior ceiling, the interior 

incandescent light is controlled automatically through a switch 

mounted in the hinge assembly to protect against breakage. Door 

openings are protected with heavy gauge stainless steel breaker 

strips. An air duct shall be mounted to the ceiling assuring low 

velocity, even air movement throughout the cabinet interior. 

Each section can accommodate a 28 1/2” x 27 1/4” x 72” cart.

Doors: Exterior shall be corrosion resistant stainless steel. Interior 

liner shall be resilient high impact ABS material formed to protrude 

beyond the door gasket to protect the gasket from tearing.  Each 

door has two edge mount, self closing, cam lift style hinges. Doors 

can be removed from the cabinet without the use of tools. Metal 

door handle shall be recessed into the door for easy grip without 

impacting aisle space. Keyed door lock is mounted in the door next 

to the handle. Lock engages into a heavy duty strike mounted to 

the cabinet face. Door gaskets are magnetic and mount to the door 

snapping in place and are removable without tools.

Refrigeration system: All components are mounted to the exterior 

of the 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 27ºF and 40ºF in heavy use food service 

operations. Refrigerant is metered using a highly responsive 

thermostatic expansion valve. System is controlled using Delfield’s 

ACT-Advanced Control Technology electronic temperature control, 

which provides improved pull down times, reduces compressor 

cycling and longer compressor life with lower energy consumption. 

Control system uses adaptive defrost to assure evaporator coil is free 

of ice and is operating at optimum efficiency. Evaporator condensate 

is eliminated using an energy efficient hot gas system.

Electrical: Standard electrical on one and two section units shall 

be 115V, 60 Hz single phase. A 10’ cord and plug is supplied and 

attached to a junction box mounted on the exterior top of the 

cabinet. Three section units shall be 115/208-230 and will require 

hardwire connections.
