Selection Procedure Performance Curves are based on 50SSU oil entering the cooler 50°F higher than the ambient air temperature used for cooling. This is also referred to as a 50°F Entering Temperature Difference (ETD). 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. but typically coolers are sized to remove 25 to 50% of the input nameplate horsepower.
