Glycol Correction Factors; Fig. 11 - Glycol Correction Factors - York MILLENNIUM YCAS Installation Operation & Maintenance

Technical Data
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.
