UniTrane Fan-Coil (Trane Company (The))

Performance Data Hot Water Reheat Coil

The following performance data represents the 1-row hot water and steam reheat coils that are available on fan-coil units in conjunction with a 2, 3 or 4-row cooling coil. Heating performance is based on 70 F (21 C) entering air temperature, 180 F (82 C) entering hot water temperature with a 20 F (-7 C) delta T.

All performance measured on high speed tap, 115 V, zero ESP, with a throwaway filter. See page 14 for performance groupings.

Note:

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

Q/ITD = MBH (kW)/(Entering water temperature -Entering air temperature) when delta T and GPM (L/s) remain constant. To determine heating capacities at a different entering water temperature or entering air temperature, compute the new ITD and multiply it by the Q/ITD shown.
