Data System Fan Coils
600 to 4000 Cfm
Carrier’s versatile belted fan coil units

satisfy design requirements:
• A selection of 8 sizes covers
capacities from 600 to 4000 cfm
• Choice of motors, from 1/4 to 5 hp,
eliminates oversizing
• Wide range of coil options for 2-pipe
or 4-pipe systems
• Optional DX coils with expansion
valve and distributor
• Single and three-phase electric
heat (1.0 to 40 kW)
Features/Benefits
42BHC UNIT The 42BHC, BVC belt drive
fan coil units provide year-
round comfort air
conditioning with central
station operating economy.
A variety of coil options
reduces first cost
Four, 6 or 8-row cooling coils combine
needed capacities with the most effi-
cient heat transfer surface. For
4-pipe systems, select either of two
split-coil options. Coils consist of alu-
minum fins securely bonded to 1/2-in.
OD seamless copper tubes. Each fin’s
aluminum collar ensures accurate con-
trol of the fin spacing, while complete-
ly covering the tubes to lengthen coil
life. All coils also feature manual air
vents, with automatic air vent available
as an option.

TOTAL WEIGHT UNIT CORRECTION FACTOR (lb)

Corner weights on pages 12 and 13 are for 8-row water filled coils. For a different number of rows, total unit weight
can be determined by the following procedure:
• Identify the number of rows and the size of the unit.
• Determine the total weight of the unit from the Corner Weight tables.
• From the table below, identify the correction factor (for size of unit and number of rows) and subtract this from the
total weight.

LEGEND NOTES:
— — Application not available 1. Contact factory if higher horsepower selection is required for a
Bhp — Horsepower given cfm and total static pressure.
2. The variable pitch motor sheave provided will allow + 15% rpm
adjustment. Unit sizes 06, 08, 10 and 12 have 3/4 in. bore fan
sheaves. Unit sizes 16, 20, 30 and 40 have 1-in. bore fan sheaves.
3. Consult factory for motor selections when outlet air temperature
exceeds 104 F on hot water coil applications.
4. Single-phase motors are only available to 2 hp. Three-phase
motors are available from 1/2 to 3 hp.
