Heatcraft Refrigeration Products BBL User Manual

•   Molded Lexan® fan guards

•   Coils have copper tubes with aluminum fins, mechanically-

bonded for efficient heat transfer. The coils are dehydrated 

and sealed

•   Textured aluminum cabinet

•   Knockouts are conveniently located for refrigerant lines

•   Screws are hardened, stainless steel with a bright   

zinc plating

•   Expansion valve mounts inside the cabinet and 

connections are sweat-type

•   Motors are thermally protected and  

 

permanently lubricated

•   Master units include the basic unit plus factory mounted 

expansion valve, solenoid, and temperature control. Also 

right-hand piping extended 8” - 12” outside the housing, 

sealed and pressurized to 20 - 30 PSI. A 1/4” OD liquid feed 

to slave is included

•   Slave units include the basic unit plus factory mounted 

expansion valve with left-hand piping extended 8” - 12” 

outside the housing, sealed and pressurized to 20 - 30 PSI

Sweat inlet connection to reduce leaks

(flare connection available as a ship loose option)

  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.
