What consequence may arise from not removing moisture from Polyol Ester Oil?

Not removing moisture from Polyol Ester Oil can lead to corrosion and potential system failure. When moisture is present in the oil, it can chemically react with refrigerant and oil, leading to the formation of acids. These acids can cause significant damage to the internal components of a refrigeration system, such as the compressor, evaporator, and condenser. Additionally, moisture can cause the oil to degrade, leading to poor lubrication and increased wear on mechanical parts. This degradation of both the oil and the metals within the system can ultimately lead to failure, requiring costly repairs or replacements. Ensuring that moisture is properly removed from Polyol Ester Oil is critical for maintaining system integrity and longevity.
