Anyone ever experence high moisture content in oil samples from 134a systems. Samples have been taken on machines that have not ever been opened up from factory. Second question why does Trane not put driers in there RTAC chillers any ideas.
I'm going to take samples agian in glass sample botttles. Maybe POE is picking up moisture through the plastic bottles. We are positive that it has never been opened up. Does anyone know the reason for no driers are they thinking that the oil is so hydroscopic that it would pull mositure if there is any from driers anyways so no point in putting them in. Just thinking.
There is not much need for a oil sample in a air cooled screw with POE oil. You are only looking for acid in the oil and yes the POE does pick up moisture through the plastic bottles. It is better to just do a acid test.

oil samples do more than just look for acid or moisture. they also look for wear metals. as for the acid test, that is a Pass/Fail type of test. an oil sample will show you the acid level and over time, you can watch it rise and make decisions before it 'fails'.
