Dielectric oil, also known as insulating oil or transformer oil, is used in high-voltage electrical equipment to provide insulation, cooling, and protection. Keeping dielectric oil clean and dry helps improve equipment safety, efficiency, and service life.
- Removes moisture to less than 3 ppm
- Degasses oil to ≤0.05% gas content
- Filters particles down to 1 micrometer
- High flow rate of 4200 L/Hr for large-volume oil treatment
- Supports vacuum oil injection
- Works with transformer vacuum drying equipment
- Supports online purification and continuous operation
- Allows unattended automatic operation
- Helps maintain stable dielectric oil quality
- Suitable for substations, power plants, utilities, and transformer maintenance projects
4200L/H Dielectric Oil treatment machine is designed for large-capacity treatment of transformer oil, insulating oil, and other dielectric oils used in high-voltage power equipment. With a high flow rate of 4200 liters per hour, this system is suitable for substations, power plants, transformer maintenance companies, and 110KV or above transmission and distribution projects.
This high vacuum purification system efficiently removes moisture, dissolved gas, and fine particles from dielectric oil. The treated oil can achieve moisture content below 3 ppm, gas content ≤0.05%, and particle filtration accuracy down to 1 micrometer. These purification results help improve oil dielectric strength, enhance insulation performance, and extend the service life of transformers and related equipment.
Equipped with a touch screen control system, the machine supports both manual and automatic operation modes. It also provides vacuum oil injection, transformer vacuum drying support, online purification, and unattended operation. For large-scale oil maintenance projects, the 4200L/Hr capacity helps reduce downtime, improve working efficiency, and ensure stable oil quality during continuous operation.

Power Transformers and Substations
Dielectric Oil Purification Systems are widely used for oil treatment in power transformers, substations, and distribution networks. They help maintain insulation performance in high-voltage and extra-high-voltage electrical equipment.
Electrical Equipment Manufacturing and Maintenance
Transformer manufacturers and maintenance service providers use dielectric oil purification during production testing, commissioning, oil filling, and scheduled maintenance to ensure stable oil quality and reliable equipment performance.
Renewable Energy and Industrial Power Systems
Wind farms, solar substations, and industrial power plants use oil-filled transformers and high-voltage equipment that require clean, dry insulating oil. Purification helps support safe operation, reduce moisture-related risks, and improve long-term equipment reliability.
