*If Required Heat Dissipation is unknown then it can either be estimated by assuming 20‐30% of the installed horsepower will be converted to heat load. However, the most accurate measure would be to calculate the heat load by recording the time the oil takes to get up to temperature with no cooler in the system. In order to calculate, the following info. is needed:
Initial Oil Temperature
°F
Final Oil Temperature
°F
Time Interval
minutes
Total Oil Volume in System
