Coalescence Oil Purifier – 150 L/Min Water Removal & Oil Dehydration System
The Coalescence Oil Purifier is a high-efficiency oil filtration system designed to remove water and impurities from various types of industrial oils. Utilizing advanced coalescence and separation technology, this machine combines precision filtration and dehydration in a single system—ensuring cleaner, more reliable oil with minimal maintenance.
It is ideal for treating transformer oil, turbine oil, hydraulic oil, and low-viscosity lubricants, especially in applications where oils contain high water content. Compared to traditional vacuum oil purifiers, this system excels in high-water-content oil purification.
