Dear friends

We are facing oil lifinting problem in Bitzer NH3 screw compressor model- OSKA 5361K,Opoeration at -6 deg. evaporation, 30 deg condensing, 150 psi discharge, We drain the 10 litre oil for evry 24 hrs running from PHE chiller surge drum. Compressor having inbuilt NRV at discharge port.

We observe that there is no oil collection neither from discharge line oil seperator nor from receiver bottom.

Please suggest to resolve the problem.

If any information required contact us.
