The freezing system is on a freezer trawler. It is a Flooded R22 system with suction temperature of -37 degrees C. Operated by 4 Grasso screw compressors. We changed to a naphthenic based mineral oil which caused blockages and poor oil return to the compressors.
What is a suggested type of oil that offers better miscibility?
