extended information

Our machines are engineered to clean, dehydrate, and degas transformer oil, switchgear fluid, and other dielectric oils. We remove:

  • Water (free & dissolved)
  • Gases (O₂, N₂, CO₂)
  • Solid particles (dust, metal wear)
  • Oxidation byproducts (acids, sludge)

These contaminants cause insulation breakdown and reduce dielectric strength. Our solutions help restore dielectric strength up to 70 kV, ensuring long-term performance of high-voltage equipment.

  • Premium Quality – ISO 9001 & CE-certified systems with ≤5 ppm moisture and ≤0.1% gas content output.
  • Dual Operating Modes – Online (continuous operation) and Offline (batch processing) flexibility.
  • Cutting-Edge Technology – Multi-stage filtration, vacuum dehydration, and degassing for restored dielectric strength.
  • Cost-Effective – Extends oil lifespan by 3–5x, reducing replacement costs.
  • Global Support – Free technical service & spare parts support in 2025.
  • Water (free & dissolved)
  • Gases (O₂, N₂, CO₂)
  • Solid particles (dust, metal wear)
  • Oxidation byproducts (acids, sludge)

Multi-stage purification:

  • Fine filtration (1–5 µm) ensures ultra-clean oil
  • Pre-filtration removes large particles.
  • Vacuum dehydration eliminates water (↓ ≤5 ppm).
  • Degassing removes dissolved gases (↓ ≤0.1%).

A specialized machine designed to remove contaminants (water, gases, particles, and sludge) from transformer oil, restoring its dielectric strength and chemical stability to extend transformer life and prevent failures.

  • Prevents insulation breakdown and electrical faults.
  • Reduces corrosion and sludge formation in transformers.
  • Complies with international standards (IEC 60422, ASTM D3487).
