This device may replace an external bypass valve, but it is not intended to bypass the total oil flow. Maximum Flow Rates Incorrect installation can cause premature failure.

Performance Curves are based on 100SSU oil leaving the cooler 40°F higher than the incoming water temperature (40°F approach temperature). IStep 1 Determine the Heat Load. This will vary with different systems, but typically coolers are sized to remove 25 to 50% of the input nameplate horsepower. (Example: 100 HP Power Unit x .33 = 33 HP Heat load.) If BTU/Hr. is known: HP = 2545 IStep 2 Determine Approach Temperature. Desired oil leaving cooler °F - Water Inlet temp. °F = . Actual , Approach |Step 3 | Determine Curve Horsepower Heat load. Enter the information from above: HP heat load...
