Hi
i have carrier chiller 30gx and experiencing low oil level for circuit A but I couldn't see any leak.
The circuit has been in normal conditions for almost a year and half since compressor changed.
What might be the cause and suggested solution?

Might be that the circuit is low on refrigerant. Check how the circuit is performing, check the sight glass, leak check the refrigerant circuit.
Might be that circuit A has been running at low capacity for long periods. Run circuit A on a high heat load, so that it runs for a long period at full capacity. See if that returns the oil.
Might be the oil is getting trapped in the economizer heat exchanger. Run circuit A at full capacity so that the economizer is brought into use, and see how the economizer is performing.
Might be a problem with the oil seperator. Check the others suggestions first.
