Performance Data
Vertical Slope Top Cabinet
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 55°F entering air temperature, 180°F entering hot water
temperature (hot water coil) or 2 psig and 5 psig entering steam pressure (steam coil) and a 15°F ΔT.
All performance measured on high speed tap, 115 V, zero ESP, with throwaway filter. Free discharge
EC motor. See Table 6, p. 25 for performance groupings.

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