Two-Pipe
Coils
ARI cooling performance is based on 80/67 F (27/19 C) entering air temperature, 45 F (7 C) entering chilled water temperature with a
10 F (5.5 C) DT.
Heating performance is based on 70 F (21 C) entering air temperature, 180 F (82 C) entering hot water temperature with a
30 F (17 C) DT.
All performance measured on high speed tap, 115 V, zero ESP, with a throwaway filter. See page 18 for performance groupings.

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 percent and 60 percent respectively of the high speed capacity.
