Application
Models BB are compact, wall-mounted units whose low
height makes them ideal for undercounter reach-in or drawer-
type xtures. The unit draws air in at the bottom and discharges
out the front. An optional air deector is included and can be
mounted over the center of the fan to direct air up and out. The
deector can be eld-formed to direct the air where needed,
usually onto drop-in trays of condiments in salad bar or sandwich
preparation xtures. An S-type mounting angle is included
to position the unit 3/4” o the wall which gives optimum air
circulation and performance.
The BBM (medium temperature) model is designed for 35°
to 40°F xture temperature with o-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
xture 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 n surface for ecient 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.
