SERIES OTR (OMNITOP COLD) SELF SERVICE
Piper Products Series OTR Refrigerated Merchandising
Cabinets provide self-service for a wide variety of foods,
while displaying them attractively in a way sure to
attract customers. The refrigeration system is carefully
engineered to hold the cold foods at temperatures
optimized for protection of their safety and appearance,
in accordance with the latest food safety standards.
CONSTRUCTION
The display section is rigidly constructed of stainless
steel, with the front open to expedite self-service. The
rear is closed by means of two glass doors which are
hinged for cleaning and re-stocking. A glass top cover
is also hinged so that it can be opened or removed for
cleaning. Both ends are closed with fixed glass panels.
The glass panels are all mounted to two stainless steel
uprights at the rear, with plastic inserts isolating the glass
from the uprights. Three glass shelves are mounted, using
stainless steel toothed racks adjustable in height. In
addition, the base is recessed for additional food storage.
The bottom of the recess consists of stainless steel plates
which can be lifted out for access to the air circulation
system. Fluorescent lights are mounted in a fixture at the
top of the display to illuminate the food.
The rear doors are double, with the outer layers sealed
into the door frames. The inner layer is perforated as
part of the air circulation system and is removable for
cleaning. The doors are hinged and can be swung out for
re-stocking and for cleaning.
The display section sits on a base which houses the
evaporator coil and the air circulation system. Around the
base, near its top, a flange is provided to support the unit
when it is installed in a cabinet or a counter.
COOLING
The food is cooled by a precisely controlled air flow pattern
that maintains 38° to 40°F within the cabinet, even though
the customer side is open for self-service. Employing blowers
and ducts, the system creates a circular flow of cold air that
covers all of the displayed food while protecting the food from
ambient temperature conditions.
NOTE 1:
Ambient conditions should be no higher than 75°F
and 50% RH.
NOTE 2:
If ambient conditions higher than 75°F and 50% RH
are expected to be encountered, the factory must be advised
of this when a quotation is requested at time of ordering.
REFRIGERATION
A frame for the refrigeration system is mounted under the
base. The system is self-contained and fully connected. It
is thermostatically controlled and includes an automatic
defrost system using hot return gas to melt ice off of the
evaporator coil. (If remote refrigeration option is selected,
the hot gas return defrost is not provided.) The refrigerant is
environmentally safe type 404a.
NOTE 1:
A 1" diameter drain pipe is provided as shown in the
drawing. This drain must contain a trap before connecting to
a floor drain or service container at time of installation.
CONTROLS
The controls are solid state, mounted on a panel and wired
for remote mounting. Included are on-off switches for lighting
and for power, and an adjustable temperature controller with
a digital readout.
CAPACITY
Capacity depends on the types of food and their containers.
NOTE: IF THE UNIT IS TO BE MOUNTED INTO A
COUNTER OR CABINET,
Front and rear ventilation louvers, each at least 25" W x 20" H,
MUST
be provided in the cabinet or counter and located so
as to provide full ventilation for the condensing unit.
