What is the Material compatibility in relation to refrigeration oils?
There are different types of refrigerant oils. Refrigerants such as R22 and R12 usually use mineral oil. But some of blended refrigerants like R410A can sometimes use a poly oil. These oils can not be blended together. So a system that already has a refrigerant with mineral oil must be charged with refrigerants with the same oil.
Floc in refrigeration oil is wax that has separated out from oil containing parathene.
