If maximum allowable flow rates are exceeded, premature failure may occur.
Maximum Flow Rates
Selection Procedure
Performance Curves are based on a 40°F approach temperature, a 2:1 oil
to water ratio and an average oil viscosity of 100 SSU. Example: oil leaving
cooler at 125°F with 85°F cooling water (125°F - 85°F = 40°F). The 2:1 oil
to water ratio means that for every GPM of oil circulated, a minimum of
1/2 GPM of water must must be circulated to obtain the curve results.
Step 1
Corrections for approach temperature and oil viscosity.

Step 2
Oil Pressure Drop Coding: l = 5 PSI; n = 10 PSI. Curves
having no pressure drop symbol indicate that the oil pressure drop is less
than 5 PSI to the highest oil flow rate for that curve. Multiply curve oil
pressure drop by Correction B.
