The Transformer Oil Filter Machine is a critical piece of oil filtering equipment designed to ensure the reliability and extended service life of high-voltage transformers, especially those rated from 330kV to 1000kV and above. It effectively removes moisture, dissolved gases, acids, and solid contaminants from insulating oil, significantly improving dielectric strength and oil purity.
This advanced industrial oil filter machine is widely used for on-site hot oil circulation, vacuum drying, and oil filling during transformer installation, commissioning, and maintenance. Equipped with a powerful vacuum pump system, it also serves as an independent vacuum source-ideal for transformer vacuum drying tasks.
Engineered as a complete transformer oil filter plant, the system combines deep vacuum dehydration and high-efficiency degassing with multi-stage precision filtration. It is capable of processing high-grade new oil and imported insulating oil, helping restore critical parameters and ensuring compliance with dielectric performance standards.
By extending oil life and reducing the need for frequent replacements, this machine also supports environmentally responsible maintenance practices. For power utilities, substations, and heavy industry, it provides a cost-effective, high-performance solution. When comparing options, the transformer oil filter machine price reflects both operational value and long-term savings, making it a smart investment in transformer lifecycle management.
Industrial oil filter machine according to decompression separation, precise filtration , spiral spray atomization separation , molecular adsorption , vacuum drying principle .The treated oil can reach the national standard using the standard.
The transformer oil enters the system through a primary filter to remove large particles, then flows into the heater for controlled heating. Once heated, the oil passes through a secondary filter and is sprayed into the vacuum chamber via a spiral atomization device, forming a fine oil mist. This mist creates a multi-layered evaporation surface within the vacuum chamber, allowing for efficient separation of moisture and gases.
Inside the vacuum tank, the oil undergoes a thorough process of dehydration, degassing, acid removal, and fine filtration. The treated oil is then collected and discharged by the oil pump through a final precision filter, completing the purification cycle.
Meanwhile, the vaporized water and gases extracted from the oil are directed into a condenser. Most of the steam is condensed into water and collected in a storage tank, while residual gases are cooled and discharged by the vacuum pump.
