Refrigeration oils, synthetic refrigeration compressor oils
The compression refrigeration machine is the most common type of refrigeration machine. Mostly synthetic refrigeration machine oil is used, depending on the refrigerant used (e.g. R134a, ammonia, etc.). The packaging units are small because refrigeration machine oil is hygroscopic. The storage time is limited. In part, this is expressed in mean delivery times.
