Electrical Oil Services (EOS) is the European specialist for recycled and new insulating oils as well as comprehensive transformer services. The company has been supporting grid operators, energy utilities and industrial customers for almost 70 years in the safe, cost-efficient and sustainable operation of electrical grid infrastructure.

With a holistic approach, EOS helps to extend the service life of existing transformers, implement modernisation projects efficiently and minimise the risk of outages. Mobile on-site services significantly reduce downtime and allow investments in new assets to be strategically deferred.

The service portfolio ranges from mobile and stationary oil processing – including drying, filtration and degassing – to the regeneration of insulating oils to as-new quality (according to IEC 60296). This is complemented by services such as maintenance, vacuum filling, as well as professional oil logistics and disposal. The proprietary EOS database supports customers in achieving efficient and transparent transformer asset management.

A central element is the sustainable EOS Closed Loop model: Used transformer oils are regenerated and returned to the economic cycle in full compliance with applicable standards. This reduces the demand for new transformer oil, lowers costs and helps operators meet regulatory and ESG objectives.

With in-house laboratory expertise, state-of-the-art mobile technology and deep practical know-how, EOS delivers tailored solutions for future-proof power transmission and distribution
