Project Background
With the continuous upgrade of power infrastructure across Central Asia, the reliability and maintenance efficiency of transformers have become increasingly critical. The client in Tashkent required a high-capacity, mobile transformer oil filtration solution to support routine maintenance and overhaul operations across multiple substations.
The main requirements from the client included:
- High on-site oil processing capacity to handle large transformer volumes within limited maintenance windows;
- A high level of automation to reduce manual intervention and operational risks;
- Strong mobility to allow the equipment to be easily deployed between different substations;
- Safe and reliable long-distance transportation with fast commissioning upon arrival.
After technical evaluation and comparison, the client selected the Chinon Filtration ZYD-250 Transformer Oil Filtration System.
Solution: ZYD-250 Transformer Oil Filtration System
The ZYD-250 is a high-performance vacuum oil filtration system for purifying high-voltage transformer oil. It is suitable for new oil filtration, in-service oil treatment, and offline oil purification during transformer maintenance.
Key Features and Configuration
- High-Efficiency Vacuum Dehydration & Degassing
The deep vacuum system effectively removes free water, dissolved moisture, and gases, significantly improving the dielectric strength of transformer oil. - Multi-Stage Precision Filtration
Progressive filtration stages remove solid particles and contaminants, ensuring high oil cleanliness levels suitable for long-term transformer operation. - PLC Automatic Control System
Integrated PLC and HMI enable automatic operation, real-time parameter monitoring, and fault alarms, reducing dependence on manual operation. - Trailer-Mounted Mobile Design
The entire system is mounted on a heavy-duty trailer, allowing quick deployment and easy relocation between job sites.
Manufacturing & Delivery Process
- Order Confirmation: PLC control system and trailer-mounted structure customized according to the client’s operational requirements;
- Factory Testing: Complete system commissioning before shipment, including vacuum level, flow rate, and filtration performance tests;
- Professional Packing: Equipment secured with reinforced fixing and moisture-proof protection to ensure safe long-distance transport;
- On-Time Delivery: On January 28, 2026, the ZYD-250 system was transported by truck and successfully delivered to Tashkent, Uzbekistan.
Project Results & Customer Benefits
- Improved Maintenance Efficiency
The 15,000 L/hour processing capacity enables the client to complete transformer oil treatment for multiple units within tight maintenance schedules. - Safer and More Stable Operation
PLC automatic control ensures stable operation and minimizes the risk of human error. - Excellent On-Site Flexibility
The trailer-mounted design allows rapid deployment at different substations, significantly reducing setup time. - Extended Transformer Service Life
By reducing moisture, gas, and particulate contamination, the treated oil helps restore insulation performance and prolong transformer lifespan.
Packing & Transportation
- The system was packed with reinforced protection, with critical components shock- and moisture-resistant.
- The trailer chassis was securely fixed during transportation to ensure stability over long distances.
- Documents supplied with the equipment include factory test reports, packing list, operation manual, and after-sales service information.
