UniTrane Fan-Coil (Trane Company (The))

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:

1. Medium and low speed capacities are approximately 80 percent and 60 percent respectively of the high speed capacity.

2. 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.)

3. High static motors need the appropriate length of duct to prevent poor acoustical applications. Heating performance is based on 70 F (21 C) entering air temperature, 2 psig (14 kPa) and 5 psig (103 kPa) entering steam pressure.
