Ordering Information
Details on how to order models AOC-08 and AOC-19 through AOC-70, specifying model series, size, relief bypass, motor requirements, and connection type.

Performance Curves and Selection Procedure
Performance curves are based on 50SSU oil leaving the cooler 40°F higher than ambient air temperature. The selection procedure involves determining the heat load, approach temperature, curve horsepower heat load, and oil pressure drop.

Oil Temperature and Pressure Drop
Typical operating temperature ranges are provided for different oil types. Systems can tolerate a pressure drop of 20 to 30 PSI, but excessive pressure drop should be avoided.

Electric Motor Data
Specifications for electric motors used in the coolers, including power, voltage, RPM, and noise levels.

Viscosity Correction
Viscosity correction values are provided for different oil types and temperatures.

Horsepower heat load x Curve Horsepower Performance Curves are based on 50SSU oil leaving the cooler 40°F higher than the ambient air temperature used for cooling.This is also referred to as a 40°F approach temperature. 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 = BTU/Hr 2545 Determine Approach Temperature. Desired oil leaving cooler °F - Ambient air temp. °F = Actual Approach Determine Curve Horsepower Heat Load....
