Lubrication issues in refrigeration compressors
Thread Content
There are many types of refrigerants used in refrigeration compressors, including ammonia, propane, and Freon. Freon itself is further divided into types such as R12/R22/R502, etc. The choice of lubricant for these compressors is quite demanding. Our factory’s refrigeration compressors use Shell Tellus lubricant, and it works well. I would like to know what lubricants others use, as well as any insights you might have regarding lubricants for refrigeration compressors. I appreciate any advice you can provide.
Our ammonia refrigeration units use Kunlun brand No. 45 refrigerant oil produced by Karamay Lubricants Company. There have been other brands in the past, but the Kunlun brand works quite well.
