Why iEngineering

Transformer Oil Filtration – At a Glance

Deep Purification

Removes moisture, dissolved gases, and solid contaminants to restore oil dielectric strength and thermal conductivity.

Extended Transformer Life

Regular filtration slows insulation ageing, reduces stress on windings, and delays costly transformer replacement.

Operational Reliability

Clean oil improves insulation margin and cooling performance, lowering the risk of breakdowns and outages.

Cost & Energy Savings

Reduce unscheduled shutdowns, extend oil service life, and minimise emergency repair and replacement cost.

Standards & Compliance

Maintain oil quality in line with industry standards and utility practices for safe, reliable operation.

Flexible Deployment

Portable, mobile, and on-line filtration options to suit substations, plants, and renewable energy sites.

Technology

Transformer Oil Filtration – Core Components & Process

Key Components of the Transformer Oil Filtration Machine

Each unit is built around a controlled process that removes gases, moisture, and contaminants from transformer oil, restoring safe insulating and cooling properties.

  • Degassing chamber – strips dissolved gases and moisture from the oil under vacuum.
  • Vacuum pump – creates the deep vacuum required for efficient moisture and gas removal.
  • Oil heater – preheats oil to reduce viscosity for better filtration and dehydration.
  • Filtration system – high-efficiency filters remove sludge, carbon, and solid particles.
  • Condensers – condense extracted water vapour and gases for safe collection and disposal.
  • Control panel – monitors temperature, pressure, flow and vacuum; automates and protects machine operation.

Machine Types & Typical Applications

Types of Transformer Oil Filtration Machines

iEngineering can supply transformer oil filtration systems tailored to different duty levels and site conditions.

  • Single-stage filtration machines – for routine oil maintenance and minor contamination.
  • Double-stage high-vacuum machines – for intensive purification of heavily aged or wet oil.
  • Mobile filtration units – trolley or trailer mounted for multi-site substation work.
  • On-line filtration systems – continuous conditioning while transformers remain in service (where design allows).

Solution Benefits

What You Get with iEngineering’s Transformer Oil Filtration Machine

Restored Dielectric Strength

Clean oil recovers insulation properties, helping to prevent internal arcing and premature failures.

Better Cooling Performance

Removal of sludge and moisture improves heat transfer and reduces hot spots in the transformer.

Reduced Outages

Proactive oil conditioning lowers the risk of unexpected trips and long-duration power interruptions.

Lower Maintenance Cost

Extend both oil and transformer life, reducing frequency of oil replacement and major overhauls.

Environmentally Responsible

Minimise disposal of contaminated oil by refurbishing and reusing existing transformer oil where feasible.

Safe & Easy Operation

Integrated controls, protection, and clear operating procedures support safe on-site filtration work.

System

Typical Transformer Oil Filtration Setup

  • Transformer connected to filtration skid via inlet and outlet hoses.
  • Heating, vacuum, and filter stages arranged in a controlled process train.
  • Condensate tank for collected water and gaseous by-products.
  • Drip trays and spill control measures for safe on-site operation.
  • Optional integration with maintenance systems (CMMS) to record oil treatment history.
