Focus on sustainability: Electrical Oil Services is expert in insulating oils and transformer services

The quality of insulating oils is responsible for the service life as well as the performance of transformers and should - be checked regularly to monitor possible deterioration. 

In order to maintain the quality of insulating oils at a constant level and to detect changes at an early stage, manufacturers (OEM) of transformers, transmission and distribution network operators as well as public utilities and industrial companies from various sectors rely on the products and services of Electrical Oil Services (EOS^®). Deviations from applicable standards must be remedied with appropriate measures in order to ensure the safe operation of the power supply networks.

For more than 60 years, Electrical Oil Services has not only offered new and recycled transformer oils for this purpose, but has also supported energy supply companies and industrial customers with comprehensive oil-processing, maintenance and repair services. In the process, sustainable and partnership-based solutions are always realised.

Customer-focused and reliable: The services of Electrical Oil Services

Electrical Oil Services provides comprehensive services for transformers and executes them with its own service vehicles. It is the largest fleet of mobile service units for transformer maintenance and insulating oil treatment in Europe!

With the help of these services, you will noticeably save costs on your transformer maintenance 

Firstly, with Electrical Oil Services downtimes are significantly reduced because replacing or processing and regenerating the insulating oil is optimised in terms of time. Secondly, you can achieve a significant extension of the service life of loaded transformers through a constant insulating oil check. 

Because even if you have already ordered a new and perhaps larger transformer, you can currently expect longer lead-times due to supply chain bottlenecks.

Furthermore, with the EOS^® Closed Loop Model, Electrical Oil Services is making an important contribution to the circular economy: 

Industrial companies as well as power supply companies use recycled insulating oil to reduce their carbon footprint. This sustainable reuse is subject to the rules and laws of waste management and enables the reprocessing of transformer oils to as-new quality according to IEC standard 60296:2020 Type B. 

New or recycled? Both!
Insulating oils and base oils from Electrical Oil Services

Whether completely new or fully recycled - the insulating oils from Electrical Oil Services ensure the function, longevity and reliability of transformers. 

We use insulating fluids (inhibited and non-inhibited transformer oil) in accordance with the international standard IEC 60296:2020, Type A or Type B:

• Recycled insulating oil EOS^® Premium:
  Our insulating oils EOS^® Premium and EOS^® Premium X are processed to meet the specific requirements of the international standard IEC 60296:2020 Type B. They are mainly used for oil changes, maintenance work and as a top-up oil after regeneration processes.

• New insulating oil EOS^® NTO:
  This pure mineral oil is based on selected crude oils and complies with the international standard IEC 60296:2020 (Type B or Type A respectively). The new insulating oil is preferably used when installing transformers as an initial filling.

In addition, Electrical Oil Services also processes used insulating oils into base oils at its own production facility in Duisburg as a certified disposal operator. These base oils are used in a wide variety of sectors, such as the printing ink industry, in civil engineering and construction, and in the production of industrial explosives:

• EOS^® Trafol^® Base Oil:
  The naphthenic base oils ensure very good solubility and are classified in category WGK 1 according to WHG. 

In addition to our oils, we offer insulating oil inhibitor concentrates, silicone fluids, synthetic esters and other products related to transformers. Would you like to get to know our entire product portfolio?
