Ammonia Compressor Oil

Inhibited Paraffinic Circulating Oil
Phillips 66®Ammonia Compressor Oil is an inhibited paraffinic circulating oil specifically developed for use in reciprocating and rotary screw compressors in industrial refrigeration systems using ammonia or carbon dioxide.

Features & Benefits

• Excellent resistance to chemical degradation

• Excellent oxidation resistance and thermal stability

• Provides longer service life than conventional naphthenic ammonia refrigeration oils

• Excellent water-separating properties

• Low pour point

• Protects against rust and corrosion

• Good foam resistance


• Refrigeration compressors using ammonia or carbon dioxide as the refrigerant

• Cold storage facilities

• Ice making machines

• Circulating systems in chemical plants and mills where contamination with moisture or aqueous gas is a problem
