Product Description
The high-efficiency vacuum oil purifier is an industrial oil‑fluid purification device developed and manufactured by companies such as Keya Filtration and Chongqing Zhongjing. It is primarily used in the power, chemical, petroleum, and metallurgical industries to remove water, degas, eliminate contaminants, and regenerate waste oils, including transformer oil, turbine oil, and lubricating oil.
This equipment features an integrated bridge‑type or vertical/horizontal configuration, offering a compact footprint and easy portability. Its core modules include a vacuum degassing unit, a three‑stage gradient filtration system, and an automated temperature‑control module. By combining vacuum separation with multi‑stage precision filtration—employing techniques such as multi‑layer flash evaporation and glass‑fiber filtration—it effectively removes water (with post‑treatment moisture content ≤3%), gases, and mechanical contaminants (filtration accuracy down to 0.5 μm), while increasing the oil’s dielectric strength to above 65 kV. The device supports multiple functions, including vacuum oil filling and hot‑oil circulation drying, making it well suited for the maintenance, regeneration, and purification of transformers, instrument transformers, and similar equipment.
