Trane RTAC POE oil
We have three 400 ton RTAC chillers that are 3 years old with 134a.
Last year they had the butterfly valve leaks and one went flat.
A contractor changed them out on all three chillers.
All went well.
Had the yearly service done and that included an oil analysis.
Last year all chillers before the valve issues had about 125 PPM of water.
Now they got 500 to 600 PPM.
Can anyone tell me is that is going to be a problem?
What level of water is cause for concern?
How to dry out? Just replace the drier cores?
I am getting conflicting opinions from people on this and need clarification.
