Key Functions of the REXON Transformer Oil Purifier:
Dehydration:
Transformer oil can absorb moisture from the environment or degrade over time, leading to the oil becoming less effective as an insulating and cooling agent. The purifier effectively removes excess water from the oil through a vacuum dehydration process, where the oil is heated and the water is evaporated and then extracted.
Degassing:
Transformer oil can also absorb gases such as oxygen, nitrogen, and carbon dioxide, which can form bubbles or affect the dielectric properties of the oil. The purifier helps in degassing the oil by applying heat and vacuum to remove dissolved gases, especially hydrogen and methane, which are common byproducts of transformer faults.
Filtration:
The purifier uses filtration systems (often including multi-stage filters) to remove particulate matter, sludge, and carbon deposits from the oil. These contaminants can result from aging transformer components or from external sources. The purification process ensures that the oil remains clean, free from debris, and able to effectively insulate and cool the transformer.
Restoration of Insulating Properties:
By removing water, gases, and solid particles, the REXON oil purifier helps restore the oil's dielectric strength (insulating properties). This is crucial for the safe operation of the transformer, as oil with high dielectric strength helps prevent short circuits and arcing.
Working process:
1. Oil Intake and Pre-Treatment
Oil enters the system: The inlet draws Contaminated oil into the purifier.
Preheating system: The oil passes through a heating system, typically using electric heating, to increase the temperature (usually between 55-65°C). This reduces viscosity and enhances the purification efficiency.
First-stage filtration (coarse filtration): The preheated oil passes through a coarse filter, which removes larger solid impurities, preventing damage to subsequent components.
2. Vacuum Separation System (Dehydration and Degassing)
Vacuum chamber function: The oil enters a vacuum chamber, where it forms an oil film or mist under negative pressure. This increases the contact area with the vacuum environment, accelerating the evaporation of water and gas.
Moisture and gas removal:
Low-temperature vacuum evaporation: Under vacuum conditions, moisture and dissolved gases evaporate at lower temperatures and are extracted by the vacuum pump.
Condensation and discharge: The separated water vapor is condensed and discharged, while the purified oil moves to the next stage.
3. Three-Stage Filtration System
Second-stage filtration (medium filtration): The oil passes through a finer filter that removes smaller particles and impurities.
Third-stage filtration (fine filtration): The final filtration stage removes ultra-fine particles, ensuring the oil meets cleanliness standards
4. Purified Oil Output
After passing through the three-stage filtration, the purified oil is delivered back to the equipment or storage tank by the outlet pump, ensuring the oil's cleanliness, moisture content, and gas content meet operational requirements. This extends equipment service life and improves operational efficiency.
5. System Monitoring and Protection
The entire system is equipped with pressure gauges, temperature controllers, vacuum monitors, and other devices to monitor the operating status in real-time. If any abnormalities occur (such as filter blockage, overheating, or insufficient vacuum), the system will automatically alarm or shut down to ensure safe operation.

Why Need Rexon Oil Purifier?
Present and future transformer ratings require high quality and high purity insulating oils at the point of use. The increasing voltage and rating of the modern transformer and electrical apparatus results in greater electrical stress in insulating material and fluids. To handle these greater stresses, oils with better dielectric qualities are required. Also lower residual water content in insulating fluids and material must be maintained. The proper treatment and upgrading of the insulating fluid will result in the improvement of the properties of the entire insulating media of power transformers. The principal functions of the insulating fluid are to serve as a dielectric material and as an effective coolant. To perform these functions, the insulating fluid must have the necessary qualities at the time of initial impregnation and filling at the factory and later maintain the same quality in the field operation.
Rexon's High Vacuum Oil Purifier upgrades the new or used electrical insulating fluids including transformer oils, polybutenes. These systems and equipment were developed as a result of 50 years of experience in vacuum treatment of electric insulating fluids.
We are the leading manufacture near 20 years experience and supply best quality and highest cost performance oil purification machines.
