Oil cleaning system HZLY-20A

The Huazheng Vacuum Oil Dehydration Cleaning Plant (Transformer Oil Purifier) is a vacuum-based oil purification system engineered to remove moisture, dissolved gases and solid contaminants from insulating oils, restoring dielectric strength and improving insulation performance. It is designed for purification of transformer oil, capacitor oil and refrigeration oil and for application on high-voltage equipment including 500 kV super-voltage transforming equipment and 220 kV transformers.
Functions / Overview

• Primary function: remove free and dissolved water, gases and mechanical impurities from insulating oils to ensure oil purity and improve insulation properties.
• Applications: oil treatment for transformers and high-voltage equipment; suitable for transformer oil, capacitor oil and freezer (refrigeration) oil.

Technical features

• Huazheng horizontal double vacuum separation technology to double evaporation area and improve evaporation efficiency.
• Coalescing oil spray separator for thorough removal of gases from oil.
• High-efficiency two-stage vacuum (HZLY series) design for dehydration and degassing.
• Fine filtration using imported American fine filter elements with a fineness of 5 μm and high filtration capacity (efficiency ≥1000).
• American heating technique using thermal radiation with constant temperature control for stable heating.
• French de-foaming technology to reduce oil leakage risk.
• Oil transport system designed for low noise and long life.
• Float valve and photoelectric oil level control for automated oil level management and reduced supervision.
• Digital PLC control for automated and reliable operation; major electrical components imported for improved system safety and reliability.
