Performance Data
VL: Cooling coil capacities (Btuh)
Notes:
n n
Coil capacity for other than 25 °F

T use the following formula:
(trm - tew)/25 x rating at 25 °F  T.
n n
To aide in balancing the water systems, all units regardless of size
have the same pressure drop across the water coils.
n n
The values in the ( ) indicate the nozzle pressure (inches of wg).
n n
The ratings above are based on 25 °F

T, 1.50 gpm water flow rate
and 8 ft water coil pressure drop (all sizes) for a single coil.
n n
All ratings include allowance for lint screens.
n n
 T = trm - tew (trm = room temperature and tew = entering water
temperature).
