The Huazheng HZLY series vacuum oil dehydration and purification plant is a transformer oil purifier designed to remove free and dissolved water, dissolved gases and solid contaminants to restore dielectric strength and extend oil service life.
Main functions
Removal of free and dissolved water, gases and mechanical/solid impurities from insulating oils.
Degassing and de-foaming to stabilize oil dielectric properties.
Fine particle filtration to protect transformer windings and components.
Applicable to 500 kV super-voltage equipment, 220 kV transformers, capacitor oil and other industrial dielectric oils.
Technical features
Huazheng horizontal double vacuum separation increases evaporation area for efficient dehydration and degassing.
Coalescing oil-spray separator for effective gas removal.
Fine filtration with American filter elements, fineness 5 μm (filtration index reported β ≥ 1000).
Thermal-radiation heating with constant temperature control for stable processing.
Low-noise, long-life oil transport system and float valve plus photoelectric oil level control to reduce manual supervision.
French de-foaming technique to prevent oil leakage during processing.
PLC-based digital automatic control and imported main electrical components for reliable operation.
Design and maintenance
Compact layout for integration into existing maintenance workflows and minimized footprint.
User-oriented interface and accessible components to simplify operation and routine maintenance.
Each unit is tested and quality-checked to meet relevant industry standards.
