Models BBM/BBL
Back Bar Reach In Unit Cooler
APPLICATION
The BB models are compact, wall-mounted units whose low
height makes them ideal for undercounter reach-in or drawer-
type fixtures. The unit draws air in at the bottom and
discharges out the front. An optional air deflector is included
and can be mounted over the center of the fan to direct air up
and out. The deflector can be field-formed to direct the air
where needed, usually onto drop-in trays of condiments in
salad bar or sandwich preparation fixtures. An S-type
mounting angle is included to position the unit 3/4" off the
wall which gives optimum air circulation and performance.
The BBM (medium temperature) model is designed for 35° to
40° F. fixture temperature with off-cycle defrost. The unit is
designed to operate at 10° to 17° TD and 16 hours per day
compressor run time.
The BBL (low temperature) model is designed for 0° to -10° F
fixture temperature, and has automatic electric defrost. The
unit is designed to operate at 8° to 15° TD with 18 hours per
day compressor runtime. The BBL has an incoloy sheath
heater embedded in the bottom fin surface for efficient and
fast defrosting. A drain pan heater is included to insure
complete condensate drainage. A disc-type sealed defrost
termination/fan delay control is mounted and wired. Field
connectors are located at the terminal board.
