Performance
Data
CAB-PRC001-EN20
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 ∆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.
6. Medium and low speed capacities are approximately 80% and 60% respectively of the high speed capacity.
