Performance
Data
CAB-PRC001-EN 21
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.
7. High static motors need the appropriate length of duct to prevent poor acoustical applications.
