may be Hasegawa compressors ? I'm russian reefer engineer and I work on vessels. What are you interesting ?

[johnirvin]

Thanks mate your there.. Yes, its hasegawa compressor. The vessel im working is a 339GT reefer, a second hand from Japan and used in the Philippines. The system is always flooded and there is an oil inside the evaporator coil, recently we drain the oil by cutting the coil and used nitrogen inside the evap coil. How to avoid the oil from entering to the system? What is the right procedure in draining oil inside the evaporator coil? Thank you again.. Johni
