Electrical Insulating Oils
EOS® Premium Regenerated Transformer Oil
EOS® Premium is a regenerated insulating oil meeting the requirements of IEC60296:2020 – “Mineral insulating oils for electrical equipment”.
Find Out MoreUnused Uninhibited Mineral Insulating Oil
EOS stores around 2 million litres of unused uninhibited mineral insulating oil, meeting the modern and exacting standard IEC 60296:2020, NGTS 3.3.1 and most other national and international standards.
Find Out MoreUnused Inhibited Mineral Insulating Oil
EOS stores around 2 million litres of unused inhibited mineral insulating oil meeting, the modern and exacting standard IEC 60296:2020, NGTS 3.3.1 and most other national and international standards.
Find Out MoreReclaimed Uninhibited Insulating Oil
Electrical Oil Services Ltd (EOS) and its ancestor companies have been producing Regenerated Insulating Oil to BS148 for more than 60 years. This provides the UK electricity supply industry, and large industrial energy users, with a sustainable alternative to resource depletion caused by the consumption of unused oil from refiners. In doing so many millions of litres of used insulating oil have been kept within the “recycling loop” and not lost to burning or other single use applications.
