TECHNICAL DATA
GLYCOL CORRECTION FACTORS
The cooler is designed in accordance with ARI-590-
92 which allows for an increase in pressure drop of up
to 15% above the design value given above. Debris in
the water may also cause additional pressure drop.
When using glycol solutions, pressure drops are higher
than with water (see correction factors to be applied
when using glycol solutions). Special care must be
taken not to exceed the maximum allowed.
A = Correction Factor
B = Mean Temperature through Cooler
C = Concentration W/W

Excessive flow, above the max GPM,
will damage the evaporator.
