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.
