What is the oil purification process?

The oil purification process involves multiple steps:
– **Heating:** The oil is heated to reduce viscosity.
– **Filtration:** Solid particles such as dirt, sludge, and metal shavings are filtered out.
– **Vacuum Dehydration:** Moisture and dissolved gases are removed by exposing the oil to a vacuum.
– **Degassing:** In some systems, further degassing is used to extract remaining dissolved gases.
This process restores the oil’s insulating, cooling, and lubricating properties, ensuring optimal performance of the machinery or electrical equipment.
