**Double Stage Vacuum Insulating Oil Regeneration Purifier / Used Oil Reconditioning Unit**
**Model NO.:** ZYD
**Trademark:** Zhongneng
**Origin:** China
**HS Code:** 8421
This **Double Stage Vacuum Insulating Oil Regeneration Purifier** is a high-performance unit designed to restore used transformer oil and other insulating oils back to their original condition. It effectively removes moisture, gases, impurities, and light hydrocarbons, ensuring the oil meets safe and operational standards.
The system operates under vacuum conditions, enhancing the efficiency of the purification process. The oil is first heated by an electric immersion heater to an optimal temperature, then drawn into a vacuum chamber where it undergoes a multi-step evaporation and filtration process. A **Duplex 3D stereo-evaporation device** maximizes surface area exposure, accelerating water removal. Any solid contaminants are filtered out using a fine filter before the purified oil exits the system.
During the vacuum process, free, dissolved, and emulsified water, along with dissolved gases and volatile substances, are vaporized and removed. The vaporized gases are captured by a rotary vane vacuum pump through a condensation trap, while the remaining vapors are safely released into the atmosphere.
