What temperature must be attained when removing oil from a low-pressure system?

To effectively remove oil from a low-pressure system, a temperature of 130 degrees F must be attained. This temperature is crucial because it ensures that the oil reaches a viscosity level low enough to flow freely, facilitating complete removal from the system.

In refrigeration practices, especially those involving low-pressure systems, controlling the temperature is vital to maintaining system efficiency and preventing potential damage. At 130 degrees F, the oil's properties allow it to be easily extracted without being too thick or causing issues during the process.

For optimal performance and maintenance of the system, adhering to the correct temperature during oil removal is essential, ensuring that all residual oil is removed to avoid contamination of the refrigerant and potential operational problems in the future. The other temperature options may be inadequate for effective oil removal, either resulting in inadequate flow or potential harm to the components of the system.
