Transformer oil purification plant - ECOIL 5000 | Ekofluid

Transformer oil purification removes moisture, dissolved gases, and solid contaminants to restore dielectric strength, essential for maintaining transformer insulation and cooling. Key methods include vacuum dehydration, centrifugal separation, and filtration to prevent electrical breakdowns and extend transformer life. Common systems, often costing $3,900 to over $14,000, can process oil on-site in live transformers.

Key Methods of Transformer Oil Purification

Vacuum Dehydration & Degassing: The most efficient method for removing water and gases by exposing heated oil to a vacuum, lowering the boiling point for rapid removal.
Mechanical Filtration: Utilizes filter cartridges to capture solid particles, rust, and sludge, often down to 1 micron, ensuring the oil is clean.
Centrifugal Separation: Uses high-speed centrifugal force to separate water and solid contaminants from the oil.
Coalescer Filters: Used to effectively remove free water from the oil.

Benefits of Purifying Transformer Oil

Restores Dielectric Strength: Removes water and contaminants to prevent insulation failure and high-voltage discharges.
Extends Equipment Life: Protects transformer internal components from rust, sludge, and acidic oxidation byproducts.
Reduces Maintenance Costs: Extends the useful life of the oil, reducing the need for costly replacements.

Common Purification Equipment Types

Vacuum Oil Purifiers (e.g., bts.net.ua XLDZJ-150): Ideal for high-level purification, removing molecular water to reach concentrations under 5 PPM.
Plate Pressure Purifiers (e.g., bts.net.ua PL-100): Simple, cost-effective machines using filter paper for removing impurities.
Mobile Filtration Units: Allows for on-site treatment (often in Alibaba.com listing) of transformers while they are in service.

Typical Process Workflow

Heating: Oil is heated to
to reduce viscosity, easing the removal of moisture and gas.
Coarse Filtration: Removes large impurities like sludge and rust.
Vacuum Treatment: Sprays oil into a vacuum chamber to vaporize water and extract gases.
Fine Filtration: Cartridges remove fine particulate matter.
Re-circulation: The oil is circulated through the purifier multiple times (4–5 times) to ensure high purity.

Note: The prices and product options mentioned are based on available market data and may vary depending on the specific, in-stock products, such as those found on Alibaba.com or at bts.net.ua.
