We test oil from lube systems supporting reciprocating, rotary, and centrifugal compressors.
The majority of the oils we test are from reciprocating compressors in continuous heavy duty industrial operation. These machines can have two different types of oils, one for lubricating a crankcase and the other for lubricating the piston cylinders. The oils commonly have different physical properties and can even be from different groups, selected to perform in contrasting operating conditions.
Rotary screw compressors tend to create wear particles in normal operation and we anticipate the effect on lube oil cleanliness. Many clients choose synthetics for bearing lubrication, since heat, thrust, and the presence of air could degrade a mineral oil more quickly over time.
The routine lube oil test slate is the same for any type of compressor, although understanding the machine and its operating conditions assist us recommending action based on laboratory test results.
