Hot Water
Reheat Coils
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) DT.
All performance measured on high speed tap, 115 V, 0.2” (.5 cm) ESP, with no filter.
See page 18 for performance groupings.

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)/(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 temperature, compute the new ITD and
multiply it by the Q/ITD shown.
3. High static motors need the appropriate length of duct to prevent poor acoustical applications.
