Polyolester (POE) Oil: The most common choice for modern r134a systems, POE is hygroscopic, meaning it readily absorbs moisture. Dark, sludgy oil usually indicates oxidation or contamination from moisture.
Understanding the R134a Oil Vacuuming Process
It must maintain compatibility with the system’s seals while resisting the extreme temperatures encountered during phase changes. Identifying Oil-Related Failures A visual inspection of the oil can reveal a tremendous amount about the health of the system.
Technicians must stay updated on the latest compatibility charts to ensure the oil matches the refrigerant used in the field, as using an incorrect type can lead to system failure and warranty voids. Types of r134a Oil Available The market offers several formulations, but two types dominate the industry.
