Oil Purification System – Advanced Oil Treatment for High-Voltage Equipment

The Oil Purification System is a modern solution designed to restore, maintain, and extend the life of transformer insulating oil. By removing moisture, dissolved gases, sludge, and particles, this system improves dielectric strength and ensures reliable performance of transformers, circuit breakers, and other oil-filled electrical equipment.

Engineered for industrial and utility-scale applications, the Oil Purification System supports both on-site maintenance and continuous in-service filtration (online mode). It also enables offline regeneration of aged transformer oil, enhancing efficiency and reducing operational downtime.

Key Features of the Oil Purification System

• Vacuum Dehydration & Degassing
  • Removes dissolved and free water along with gases such as oxygen and hydrogen. This ensures optimal dielectric properties for transformer oil.
• Multi-Stage Filtration
  • Filters contaminants down to ≤1 micron using high-capacity cartridges, protecting transformer windings and extending oil life.
• Thermal Oil Heating
  • Precisely controlled heating accelerates dehydration and degassing without degrading the oil.
• Automatic PLC Control
  • User-friendly PLC interface provides real-time monitoring, alarms, diagnostics, and fully automated operation for safe and efficient performance.
• Optional Oil Regeneration
  • Activated clay or fuller’s earth removes acidity, sludge, color, and oxidation byproducts from aged oil, restoring near-new condition.
• Portable & Skid-Mounted
  • Trailer-mounted or skid-mounted units allow easy deployment at transformer yards, workshops, or substations.
• Online Filtration Capability
  • Purifies oil while in service, minimizing downtime and operational disruption.
• Flow Rate Options
  • Customizable from 600 LPH to 6000+ LPH to suit both small and large transformers.
