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

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
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
