steam
coils
Heating performance is based on 70°F (21°C) entering air temperature, 2 psig (14 kPa) and 5 psig (103 kPa) entering steam pressure.
All performance measured on high speed tap, zero ESP, with a throwaway filter.

Note:
Q/ITD = MBh (kW)/(saturated steam temperature - entering air temperature) when
∆
T and gpm remain constant. To determine heating capacities at a different saturated steam or entering
air temperature, compute the new ITD and multiply it by the Q/ITD shown.
