What temperature is recommended for removing oil from a low-pressure system?

The recommended temperature for removing oil from a low-pressure system is 130 degrees Fahrenheit. This temperature is significant because it strikes a balance between being high enough to lower the viscosity of the oil, facilitating easier removal, while still being safely below the boiling point of the refrigerant and oil mixture.

At this temperature, the oil becomes less viscous, allowing it to flow more freely and be evacuated effectively from the system. This is crucial for maintaining the efficiency and performance of the refrigeration system, as residual oil can interfere with the operation of components and can lead to issues such as compressor failure or reduced cooling capacity.

Additionally, while other temperatures, such as 120 and 140 degrees Fahrenheit, might seem viable, they either do not effectively optimize the flow of the oil or could pose risks associated with boiling refrigerants or damaging components at higher temperatures. Hence, 130 degrees Fahrenheit is acknowledged as the best recommended temperature for this process in the context of servicing low-pressure refrigeration systems.
