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 shown
on page 40. 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 flow
rate allowed.
A= Correction Factor
B= Mean Temperature through Cooler
C= Concentration W/W
Excessive flow, above the max. GPM,
will damage the evaporator.
