| Performance Data
ARI
ARI cooling performance is based on 80/67 F (27/19 C)
entering air temperature, 45 F (7 C) entering chilled water temperature wit a 10 F (5.5 C)
delta T.
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) delta T.
All performance measured on high speed tap, 115 V, zero
ESP, with a throwaway filter. See page 14 for performance groupings.

Note:
- CFM = Cubic feet per minute
- TMBH = Total capacity (MBH)
- GPM = Gallons per minute
- WPD = Water pressure drop (feet of water)
- QATD = MBH (kW)/(Entering water temperature - Entering air
temperature) when delta 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 CMTD shown.
- Medium and low speed capacities are approximately 60 percent
and 60 percent respectively of the high speed capacity.
