The cooler is designed in accordance with
A
RI-590-92 which allows for an increase in
pressure drop of up to 15% above the design value
shown on pages 48-51. 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.

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 Pages 63
through 66. Debris in the water may also cause addi-
tional 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 WIW
Excessive ow, above the max. GPM, will
damage the evaporator.
