Yellow is the new white: EOS® recycled insulating oil is this pure

Written by Kilian Gerbl | Jul 2, 2024

Electrical Oil Services specialises in insulating oils and related services for transformers and switchgear. Although the recycled and certified EOS® Premium transformer oil has a slightly different colour than a new insulating oil, it is comparable to a new insulating oil in every other respect. EOS® Premium recycled transformer oil is produced under strict quality controls and is certified, making it a sustainable and reliable alternative to conventional insulating oils. In this article we take a closer look at the benefits of recycled transformer oil.  

 

Only its colour differentiates EOS® recycled insulating oil from new oil

The chemical and thermal properties of the EOS® Premium insulating oil recycled by Electrical Oil Services are identical to those of new insulating oil. Only the colour changes slightly as a result of the recycling process. Scientific studies have confirmed that this colour change has no influence on the quality of the transformer oil. This is why our product has also been certified as an insulating oil with as-new properties.

 

Recycled insulating oil EOS® Pemium is certified as good as new


EOS® Premium regenerated insulating oil meets the requirements of the International Standard IEC 60296:2020:

  • This standard deals with mineral insulating fluids for electrical equipment.
  • It applies regardless of the origin of the equipment and therefore covers both new and regenerated insulating oils.
  • EOS® Premium is available in non-inhibited or inhibited versions (EOS® Premium X) as required.

The recycled insulating oil EOS® Premium has been certified by the laboratory of Siemens Energy Global GmbH & Co KG as an insulating oil with as-new properties. It is ideally suited for use in insulating oil service and maintenance work on on-load tap-changers and transformers as well as for use during oil changes.

Recycled insulating oil as a sustainable alternative reduces transformer oil waste

Cost pressure and the goal of using resources responsibly are driving many industrial companies and energy suppliers to rethink their approach: They are increasingly using recycled insulating oil for their transformers instead of using new transformer oil.

This makes them part of the circular economy by avoiding waste and utilising resources more efficiently. Companies that use EOS® Premium recycled transformer oil are demonstrating a strong commitment to sustainability and the circular economy.

By using recycled insulating oil, responsible companies actively contribute to the circular economy and strengthen their position as an environmentally conscious company. With the IEC 60296:2020 certified product EOS® Premium, Electrical Oil Services offers a recycled transformer oil that is cost-efficient, sustainable and reliable. Even though the colour of the recycled insulating oil appears slightly yellow, all of its chemical and thermal properties are equivalent to those of a new insulating oil. Recycled insulating oil such as EOS® Premium is therefore a sustainable alternative for modern energy suppliers and industrial companies.
