How does industrial oil purification work?

Industrial oil purification works by removing contaminants such as water, solid particles, and dissolved gases from lubricating, hydraulic, and transformer oils. The process typically involves heating the oil to reduce viscosity, passing it through filtration systems to remove solids, and using vacuum dehydration to extract moisture and gases. This restores the oil’s insulating and lubricating properties, extending the lifespan of machinery and equipment.
