Versa Drawer Refrigeration Units
INTRODUCTION
GENERAL
Versa Drawer series refrigeration units have two or four
drawers, each of which can operate in one of four modes
at any time. The two-drawer and four-drawer models
feature countertop-height stainless steel work surfaces.
A two-drawer Lo Profile unit is also available.
Refrigeration mode:
The drawer operates as a
refrigerator, maintaining the refrigeration set point
between 32°F and 41°F.
Freezer mode
: The drawer operates as a self-defrosting
freezer, maintaining the freezer set point between -5°F
and 5°F.
Thaw Cabinet mode
: The drawer operates as a thaw
cabinet, maintaining the thaw cabinet set point between
32°F and 50°F using hot gas and refrigeration as required
for a fixed time period. Once the period has elapsed, the
drawer mode is changed to refrigeration mode.
Convenience Chiller mode
: The drawer operates as a
convenience chiller, maintaining the convenience chiller
set point between -5°F and 25°F for four hours. Once the
period has elapsed, the drawer mode is changed to
refrigeration mode.
All units have stainless steel exteriors and interiors. Drawer
gaskets are magnetic and mount to the drawer, snapping in
place. The gaskets are removable without tools.

THAW SYSTEM
Hot gas is used for the thaw cabinet operation and the
defrost mode. A hot gas solenoid controls the heat. In the
defrost mode the hot gas will be used to warm the
evaporator coil when a drawer is used as a thaw cabinet.
The hot gas solenoid will open to maintain drawer
temperature.
REFRIGERATION SYSTEM
The refrigeration system is used in all modes. The
refrigeration solenoid controls refrigerant. Two compressors
run in parallel operation in a four-drawer system while one
compressor operates the two-drawer system.
TEMPERATURE MONITORING
Temperature sensors are located in each drawer. The
drawer temperature is displayed on the control panel.
CONTROLLER
The controller provides information indicating the drawer
mode. In addition, the actual temperature of the drawer is
displayed. The push button tabs, located next to the
display screen, represent each drawer. These tabs are
used to select the drawer for control. The control display
located on the right side of the control panel is used to
toggle between control screens and to select drawer
modes and temperatures.
