Transformer Oil Regeneration

Insulating Oil Purification & Regeneration by IOANNIS MAVROGENIS P.C.

IOANNIS MAVROGENIS P.C. provides complete transformer insulating oil regeneration and purification services, aiming to restore critical electrical and chemical properties of the oil and extend the safe operating life of your equipment.

What is Oil Regeneration?

Removal of ageing by-products: Eliminates oxidation residues such as acids, polar compounds, and sludge.
Moisture & gas reduction: Removes water and dissolved gases that affect insulation performance.
Contaminant filtration: Reduces particles and contaminants that accelerate degradation.
Performance improvement: Helps improve key indicators like acidity, BDV, moisture, tan δ / DDF, and IFT, depending on oil condition and maintenance requirements.

Our Process

Filtration & vacuum dehydration/degassing: Removes moisture, gases, and fine particles to stabilize the oil.
Adsorption-based regeneration: Uses adsorption columns to remove ageing by-products and improve oil chemistry.
Before & after verification: Measurements/analyses documented in line with your maintenance requirements.

Customer Benefits

Reduced failure risk: Improved oil quality supports reliable transformer operation.
Extended service life: Protects the transformer insulation system and helps prolong asset life.
Cost-efficient alternative: Lower cost compared to full oil replacement, where technically feasible.
Documented results: Clear reporting with measurement data and service records.
