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 1/2-in.

OD seamless copper tubes. Each fin’s

aluminum collar ensures accurate con-

trol of the fin spacing, while complete-
