ZY.Series Portable Transformer Oil Purification Plant

The ZY.Series Portable Transformer Oil Purification Plant is engineered for on-site regeneration of insulating oils in energized or de-energized transformers. Combining high-vacuum degassing/dehydration with multi-stage filtration and optional regeneration earth, it removes moisture, gases, acids, sludge, and color bodies to restore dielectric strength and extend transformer life.
Available from 6 to 300 L/min, the ZY.Series covers everything from spot maintenance to large fleet service.

Model Options

Configuration

Key Features

  • High-vacuum degassing & dehydration (thin-film vacuum tank)

  • Multi-stage filtration: 80 µm → 20 µm → 1–5 µm

  • Optional regeneration module for acidity/sludge removal

  • Closed-loop heating with precise temperature control (0–100 °C)

  • Safety: over-pressure, anti-froth, low-oil, E-stop, interlocks

  • Portable: skid or trailer; weatherproof enclosure optional

  • Simple HMI with digital monitoring and data logging
