provides 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 
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

-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.

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.
