Tamir,
Tell us a bit more about system.
Does it lose oil when running, or if cycled off?
What type of oil separator/s does it have, any coalescer type, is oil return working?
Is it getting floodbacks?
Is it a new system, has it worked OK in the past?
A few pictures etc

HI Ranger,
its a climaveneta Italian chiller.
Yes its losing oil only when running, when the compressor shuts down the oil returns after a few minutes.
It has an internal oil separator (you can see in the pictures).
this compressor got a tiny overhaul , bearings and gasket replaced.
the system worked fine before.
Many Thanks

Most likely issues;
- Lack of refrigerant
- Poorly adjusted EEV/TEV
- Oil line/flow issues

Hi Viking
I check all the above and they are fine.
Its the weirdest thing, the compressor can run 10 minutes and lose the oil or it can happen after 7 hours...
Its runing on r134a with solest170 oil..
Any chance that an jamed oil filter can cause the issue?
