Acids are formed in the presence of moisture, heat and oxygen.  Acids are also formed as a result of ageing oil. The Total Acid Number (TAN measured) indicates oil's total acid content of oil, but not the strength of the acids.

Reducing the acidity of oil, for instance transformer oil or gas engine oil, reduces the ageing of the oil and the wear on equipment. In doing so, equipment reliability and lifetime are increased.

CJC™ depth filtration prevents acid formation in oil by keeping contaminants and moisture levels low.





in order to significantly increase lifetime of special fluids/oils such as phosphate esthers.
