Transformer Retrofilling

Replacing mineral oil from an existing transformer with ester dielectric fluid is a cost effective, safe, and environmentally friendly option to upgrade your transformer. We assess your requirements, advise on your retrofilling options, and undertake retrofilling in our certified transformer workshops. Benefits of retrofilling with ester oil include: 

  • Reduced fire risk which improves safety and business continuity, as ester oil has high fire point. 

  • Avoiding environmental contamination through either a minor leak or catastrophic failure, as Ester oil is bio-degradable. 

  • Increased transformer life and delayed replacement due to superior water tolerance. 

  • Reduced operating expenditure and asset reliability particularly in areas prone to wet conditions. 

  • Ampcontrol is a Midel Service Partner.
