In this video we introduce you to the sustainable EOS Closed Loop model. Learn why it makes sense to recycle transformer oil and return it to the cycle.


As a pioneer in oil processing and oil regeneration, Electrical Oil Services (EOS) has been recognised as a leading provider in Europe for years. EOS collects used insulating oil, recycles it and returns it to customers in as-new condition. This is reuse on a sustainable basis - we call it the EOS Closed Loop Model.

EOS Closed Loop Model: Reducing the impact on the climate and cutting costs with recycled transformer oil

In view of increasing demands for climate protection and economic efficiency, companies and public institutions are examining their energy technology systems for efficiency and looking for solutions to optimise them. Transformers are also being put to the test in this context. One possibility for optimisation is the regeneration of transformer oil. This process improves the quality of the oil and thus also the performance and service life of the transformers - in addition, valuable resources are conserved.

This is how circular economy works: The EOS Closed Loop Model

Regenerating insulating oils from transformers enables customers to manage transformers sustainably. The EOS® Closed Loop Model is subject to the usual rules and laws of waste disposal. It makes no difference whether your insulating oil is regenerated at our production facility or directly on site.

We offer the following recycling services:

Stationary oil regeneration in a production plant:
Here, used transformer oil is collected from the customer's site and processed in one of Electrial Oil Services' own production facilities. The resulting oil quality is as good as new, meets the IEC 60296:2020 standard and is returned to the cycle as recycled insulating oil.

Mobile oil regeneration directly on site:
The mobile process goes one step further and not only recycles the insulating oil, but also treats the entire insulating system of a transformer. This is a great advantage because it enables deep cleaning, which can significantly increase the service life of transformers. This process is similar to dialysis: ageing products such as peroxides, acids and sludge are removed from the insulating oil and the insulating oil is reprocessed to as-new quality. Depending on the requirements, mobile regeneration under load is possible during operation or outside operation - taking into account all safety aspects.

Whether regenerated stationary or on site, the Electrical Oil Services product that results is a high-quality recycled insulating oil.

Recycled insulating oil: EOS Premium according to IEC 60296:2020
The EOS Premium product from Electrical Oil Services is a regenerated insulating oil that fully complies with the requirements of the IEC 60296:2020 Type B standard. Through reprocessing, the recycled transformer oil can be returned to the circular economy. This means that waste, such as the disposal of used transformer oil through incineration, can be avoided. The circular economy ensures that materials such as insulating oil are reused, reprocessed and recycled for as long as possible. This significantly extends product life cycles and conserves valuable resources.
