  Trane Company (The) UniTrane Fan-Coil UniTrane Fan-Coil - Page 22
| Performance Data
Steam
Reheat Coil
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, 115 V,
zero ESP, with a throwaway filter.

Note:
- Medium and low speed capacities are approximately 80 percent
and 60 percent respectively of the high speed capacity.
- Q/ITD = MBH(kW)/(Saturated steam temperature - Entering air
temperature). To determine heating capacities at different entering steam pressure or
entering air temperature, compute the new ITD and multiply it by the Q/ITD shown. (See the
Steam Properties table at the end of this section to determine the saturated steam
temperatures at various entering steam pressures.)
