What is the maximum moisture content allowed in an oil sample drawn from a centrifugal compressor?

The maximum moisture content allowed in an oil sample drawn from a centrifugal compressor is indeed critical for ensuring the proper functioning and longevity of the equipment. A limit of 100 PPM (parts per million) indicates a balance between maintaining sufficient lubrication and preventing moisture-induced corrosion or other issues.

Moisture content can lead to a number of problems in compressors, including reduced lubrication efficiency, increased wear, and potential damage due to corrosion. By establishing a maximum allowable moisture level, maintenance personnel can take necessary actions if water contamination is detected. A limit of 100 PPM is generally considered acceptable for many systems, as anything higher can begin to create conditions that might adversely affect performance and reliability.

Understanding these limits helps operators ensure that the lubrication system remains effective while minimizing risks associated with moisture contamination.
