Why need transformer oil filtration machine:
Transformers play an important role in the power industry. The transformer converts the power to the appropriate level for safe use in collaboration with other components of the system. Transformer maintenance is required to ensure long-lasting life. In addition, high quality, clean oil is essential for transformers to provide efficient performance.
A transformer oil refining machine is required for the treatment and purification of transformer oil. Insulating / transformer oil filtration is the process of removing sludge and moisture from transformer oil. Using transformer oil purifiers can improve oil insulation, extend the life of transformers and reduce transformer failures. There is no question that owning a good machine can bring a good return on investment. Maintenance of transformer oil is required for the effective operation of the transformer. This not only helps increase the life of the device but also increases the efficiency of the device.

The REXON Double Stage High Vacuum Transformer Oil Purifier is a state-of-the-art solution designed for high-capacity transformer oil purification. With a flow rate of 9,000 liters per hour, this machine is engineered for large-scale power plants, substations, and transformer service companies that require efficient, high-performance oil treatment. By utilizing dual-stage vacuum technology, the purifier removes harmful contaminants, including moisture, dissolved gases, and solid particles, ensuring the insulating oil meets optimal quality standards. This process not only restores the dielectric strength of the oil but also extends the lifespan of the transformer, reducing downtime and maintenance costs.
The double-stage high vacuum system operates under a vacuum pressure as low as ≤5 Pa, which is critical for the effective removal of moisture and gas content from the oil. This advanced filtration technology ensures the highest level of cleanliness and consistency in oil purification, making it ideal for transformer oil regeneration and routine oil maintenance.

The multi-stage filtration process guarantees that solid contaminants are effectively filtered out, with a precision level that can filter down to 1 micron. This results in cleaner oil, enhanced insulating properties, and significantly improved transformer performance.
