Read our primer articles on Oil Analysis and Tribology

Hi all!

I would like to check the aging of refrigeration compressors oil. I'm searching for simple and economical ways of determining the oil status. Apart from viscosity, I thought to measure TBN or TAN.
For an internal combustion engine, it looks like TAN is a good indicator of oil age, but in my case, the compressors are working with ammonia (basic) and there is no combustion.
Do you think a measure of TAN would still be useful or should I check for TBN? Or neither TAN nor TBN are useful?

Any suggestions welcome, thank you all in advance

Regards

Marko Germani
