Performance Steam
DataCoils
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 DT 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.
