Satisfy All Your Design Requirements
with Carrier’s Versatile 42BH Fan
Coil Unit
• A selection of 6 sizes covers capaci-

ties from 800 to 4000 cfm

• Choice of motors, from

1

4

to 3 hp,

eliminates oversizing

• Wide range of coil options for

2-pipe or 4-pipe system

• Optional DX coils with expansion

valve and distributor

Features/Benefits

The 42BH fan coil unit pro-
vides year-round comfort air
conditioning with central
station operating economy.

A variety of coil options
reduces first cost

Four- or 6-row cooling coils combine
the capacities you need with the
most efficient 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 control of the fin spacing,
while completely covering the tubes to
lengthen coil life. All coils also fea-
ture manual air vents, with automatic
air vent available as an option.

Fan wheels are designed to
provide low operating costs

The forward-curved, centrifugal,
double-inlet fans are statically and
dynamically balanced at the factory to
minimize transmission of vibration
to the building structure.

The belt-driven motor has a variable-

pitch pulley which adjusts at the job-
site to accommodate limited ranges of
air quantities and pressures.
