Hydronic Auxiliary Coils
All hydronic coils are wavy plate
finned and available in varied ca-
pacities (Table 7 and 8 listed be-
low). The coils are hydrostatically
tested at 350 PSI.
A manual air vent is installed on
the return header. All auxiliary
coils have opposite end supply/re-
turn connections from the main
coil.
See Figure 12 for auxiliary
PREHEAT coil header sizing,
and Figure 13 for auxiliary RE-
