Performance
Data
CAB-PRC001-EN 19
Hot Water
Coils
Heating performance is based on 70 F (21 C) entering air temperature, 180 F (82 C) entering hot water temperature with a 30 F (-1 C)
∆T. All performance measured on high speed tap, zero ESP, and a throwaway filter.

Note:
1. CFM = Cubic feet per minute
2. TMBH = Total capacity (MBH)
3. GPM = Gallons per minute
4. WPD = Water pressure drop (feet of water)
5. Q/ITD = MBH (kW)/(Entering water temperature - Entering air temperature) when DT 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.
6. Medium and low speed capacities are approximately 80 percent and 60 percent respectively of the high speed capacity.
