This device may replace an external bypass valve, but it is not intended to bypass the total oil flow.

Four Pass FLANGE O-RING BSPP BSPP BSPP NOTE: We reserve the right to make reasonable design changes without notice. All dimensions are in inches. 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...

Curve Number Model Desired Reservoir Temperature Return Line Cooling: Desired temperature is the oil temperature leaving the cooler. This will be the same temperature that will be found in the reservoir. Off-Line Recirculation Cooling Loop: Desired temperature is the temperature entering the cooler. In this case, the oil temperature change must be determined so that the actual oil leaving temperature can be found. Calculate the oil temperature change (Oil AT) with this formula: Oil AT=(BTU's/Hr.)/GPM Oil Flow x 210). To calculate the oil leaving temperature from the cooler, use this...
