Wuhan, China – April 28, 2026 – Wuhan Moen Intelligent Electric Co., Ltd. (MOEORW), a leading provider of power equipment testing and maintenance solutions, officially launched the MOEORW-WBL20 high-efficiency double-stage vacuum oil purifier. This compact, mobile oil treatment unit is purpose-built for insulating oil regeneration in transformers, mutual inductors, circuit breakers, and other critical power apparatus.
Engineered for on-site live working, the MOEORW-WBL20 efficiently removes water, gas, and particulate contaminants to restore oil dielectric strength, ensuring safe, stable operation of power grid and industrial power equipment.
Key Advantages
- Double-stage vacuum & Roots booster system
Delivers strong vacuum for deep dehydration and degassing. The Roots pump automatically starts above 3000 Pa and stops below 6000 Pa for optimized efficiency.
- Compact & mobile design
Equipped with movable casters and requires no foundation installation, making it ideal for substations, factories, and emergency response sites.
- Fully automatic & safe operation
Features infrared liquid level control, pressure protection (0.6 MPa), temperature interlock (45–65 °C, optimal at 65 °C), and emergency stop.
- Multi-stage filtration & integrated heating
Coarse and precision filters remove particles; built-in heater accelerates moisture evaporation.
- Multi-functional performance
Supports insulating oil purification, power equipment drying, and vacuum oil filling for transformers, bushings, and instrument transformers.
Working Principle
Oil passes through the primary filter to remove large particles → heated → enters the vacuum separator for water and gas removal → fine filtration → outputs clean, high-insulation oil.
Application & Operating Features
- Operating temperature: −25 °C to +45 °C, suitable for high-altitude sites
- Supports safe on-site live working in fine weather with proper supervision
- Easy maintenance: filter cleaning, vacuum pump oil replacement, seal inspection
- Full protection: pressure control, leak detection, motor overload protection
