Selection Procedure Desired Reservoir Temperature Performance Curves are based on 50 SSU oil entering the cooler 50°F higher than the ambient air temperature used for cooling. This is referred to as a 50°F E.T.D. Oil Temperature: Oil coolers can be selected using entering or leaving oil temperatures. Step 1 Determine the Heat Load. Heat load may be expressed as either Off-Line Recirculation Cooling Loop: Desired reservoir temperature is the oil temperature entering the cooler. horsepower or BTU/Hr. To convert horsepower to BTU/Hr.: BTU/HR = Horsepower x 2545 temperature is generally the...
