Features/Benefits
The 42BH fan coil unit
provides 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
aluminum 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 feature
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 jobsite
to accommodate limited ranges of air
quantities and pressures.
