Chiller Oil Particle Counts

Did the laboratory follow up on the high particle count with a ISO Cleanliness code via filter patch test and view under a microscope to determine the cause of the high counts? Not sure what other tests were done on the sample as well. Have other samples been taken since the high count to determine if sampling issues may have caused the high counts?

We have taken another oil sample to verify the first analysis results but we have not received them back from the lab yet. I am not aware of the follow-up tests the lab performed to determine the "cause" of the high particle counts. I have never heard of a lab using testing to determine the "cause". I was under the impression that if the particles were high and they were not metal, then they are must be dirt.

I don't know about your chillers, but I do have issues with compressor oils and our lasernet fines particle counter.

Gasses entrained in the oil give the lasernet fits.

Ask York what they consider a condeming limit.

they may have a limit for total wear metal ppm and/or particles ask them they should know what there equipment needs.

sorry re read your post if York says it is OK then I would trust them

Refrig Guy, thank you for your response. You added a lot of value to this conversation. Are you aware of any resources I could contact to get more information on chiller oil samples?
