Chongqing TOP Oil Purifier Co., Ltd. is one of the most reliable manufacturers and suppliers of Transformer Oil Treatment Equipment in China, also supports customized service. Please feel free to buy advanced Transformer Oil Treatment Equipment made in China here from our factory.
Moisture, dirt and dissolved gases can build up in transformer oil during operation and maintenance, affecting its insulating performance. If the oil is not properly treated, it can increase the risk of transformer problems and unplanned shutdowns.
Our Transformer Oil Treatment Equipment is designed for on-site transformer oil treatment. It combines a two-stage high-vacuum system with multi-stage fine filtration to remove moisture, dissolved gases and solid contaminants from the oil.
The two-stage high-vacuum system removes moisture and dissolved gases from transformer oil, while the multi-stage fine filters remove solid particles and other impurities.
Under normal treatment conditions, moisture content can be reduced to below 3 ppm. The dielectric strength of the treated oil can be restored to meet applicable international standards.

Suitable for Field Maintenance
The equipment is designed for practical power maintenance applications, including:
- Power substations
- Transformer repair and maintenance workshops
- Mobile maintenance vehicles
- On-site transformer servicing
It can be used in different working environments, including humid coastal areas, cold mountainous facilities and busy repair workshops. The system is designed for extended operation during oil treatment, so maintenance personnel do not need to continuously monitor the equipment.
Simple Operation and Maintenance
- The operating process is straightforward. The operator positions the unit, connects the oil hoses, starts the equipment and monitors the treatment process.
- No complicated programming or specialized training is required for normal operation.
- Built-in safety protection helps shut down the equipment when abnormal operating conditions occur. Routine maintenance is also simple, and filter replacement can generally be completed within about 10 minutes.
- Heavy-duty components are selected for regular industrial use and long operating periods.
Configurations for Different Applications
Different transformer maintenance jobs may require different equipment configurations. We can customize the Transformer Oil Treatment Equipment according to the application, including treatment flow rate, mobile skid-mounted designs and other structural or functional modifications.
This allows the equipment to be configured for fixed maintenance facilities as well as mobile transformer servicing.
Manufacturing and After-Sales Support
We have been manufacturing transformer oil treatment equipment in Chongqing for more than 20 years. Our equipment has been supplied to customers in Southeast Asia, Europe, the Middle East and other international markets.
The equipment carries CE and ISO certifications, and each unit is tested before shipment.
Our after-sales team provides support for equipment operation, maintenance and replacement parts. For customers with specific site requirements, we can also discuss the application and equipment configuration before production.
