advanced eco-smart products and solutions

Sustainability in focus

SEM is committed to playing a key role in delivering the energy solutions of tomorrow. We support long-term global sustainability as a core business vision. Our products significantly reduce energy consumption and offer true zero CO2 emissions.


Hydrogen is gaining momentum globally, and transforming the combustion engine landscape – this can be clearly seen within the heavy duty on highway market, but also in other applications such as power generation. With exceptional performance and technical precision, our advanced ignition systems are driving a new generation of hydrogen engines. True zero CO2 – contributing to a sustainable future.

Unique ion-sense solution

Our unique ion-sense solution uses the ion current to precisely monitor combustion. Ignition timing can then be optimized in real-time using peak pressure position. This technology is at the forefront of engine performance efficiency innovation and provides significant fuel savings. Spark voltage monitoring is used to maximize sparkplug life and offer extended and predictable service intervals. Both of these techniques result in substantial reductions in Total Cost of Ownership.

Electricity as a sustainable energy source

Electricity as a sustainable energy source has in recent years become an increasingly major focus for manufacturers in the automotive industry. SEM is also at the leading edge of this evolution – with extensive knowledge from electromagnetism, electronics, system architecture and automotive applications, we offer customized solutions for electric drive applications.

Go Green – Go Economical

We provide our customers advanced eco-smart products and solutions

Precision and environmental concern

SEM’s original idea remains firm; We shall develop and manufacture products that, in an energy-effective manner, initiate, generate and transform power. Performance and technical precision have gradually been extended with environmental requirements. Within the company there is an intensive, ongoing process to develop technology that can make a positive contribution to the environment.

Caring about our environment

When it comes to the environment we are at the very forefront of development. Together we develop solutions that reduce energy requirements and remove emissions of harmful substances. We are inspired by national and international environmental goals and comply with current environmental legislation. We always strive to reduce our own environmental impact and prevent pollution. Each year, we compile the results of our environmental work, in both quantitative and qualitative terms, which forms the basis for our new environmental objectives in the coming years.

SEM is certified in accordance with ISO 9001, IATF 16949, ISO 14001 and ISO 45001.

Precision and quality

To SEM quality is a measure of our performance from the customer’s point of view. Our success in the market depends on the ability to understand and satisfy customers need for high quality products and services. We have zero tolerance for errors in products and processes and work systematically with continuous improvements in our products and processes efficiency.
