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
