Description
Steam only-
Main Coil
Steam Main Coils
(K1 and K2 coils)
The steam heating coil is a 1-row
design, tube-in-tube distributing
coil. Supply and return connec-
tions are on the same side, and are
terminated with a 1-inch female
pipe connection.
For steam only coils, K1 and K2,
Trane provides a face and bypass
damper selection. When factory
mounted Trane controls are se-
lected, an optional 2-position iso-
lation valve may be used to close
off flow to the steam coil when the
damper is in the full bypass posi-
tion.
For field installed controls, Trane
provides a face and bypass damp-
er ONLY. See Figure 14 for main
coil header sizing for 2-pipe
and 4-pipe systems. Right
hand configuration shown.
