EOS® Premium – Regenerated Transformer Oil

EOS® Premium – Regenerated Transformer Oil

At EOS, we remain committed to the future of insulating oil recycling throughout Europe and the United Kingdom.

Building on our “CLOSED LOOP” model we have developed EOS® Premium, a regenerated insulating oil meeting the operational requirements of IEC60296:2012 – “Unused mineral insulating oils for transformers and switchgear”.

What does it do?

Use  EOS® Premium with confidence as part of your maintenance and refurbishment activities as an alternative to unused (new) insulating oil.

EOS® Premium is perfect for switchgear oil changes, tap changer maintenance, transformer refurbishments, DBDS or PCB oil changes.

  • The green alternative to Unused Oil
    • Recycle DON’T burn!
    • Offers full traceability
  • “As New” properties – meets the operational requirements of IEC 60296
  • Uninhibited or inhibited options
  • Price stable and secure supply – you supply the feedstock (used insulating oil)
  • Stops a valuable resource being wasted.

EOS® Premium has a “non-detectable” PCB content and completely without additives.


Water content (mg/kg)<30 (typically <10)
Breakdown voltage (kV)>30 (typically >60kV)
Acidity (mgKOH/g)<0.01
Oxidation stability (164hrs)<1.2 mgKOH/g total acidity < 0.8% sludge
PCB content (ppm)Non detectable
