Our Philosophy


The most important thing about our work is for us to meet the highest standards and to generate the greatest possible benefit for our customers.


We strive always to be open-minded and flexible in our work practices and technical solutions. We nurture a forward thinking development culture that is technically innovative and socially responsible.

Quality and assurance

State-of-the-art means that whatever we do today can always be done better tomorrow. We consult, coach, and guide our customers from the first idea to the final decommissioning of the product.


Believing that we are good, is not good enough, our customers must share our belief. We invest in high tech projects and products. Our customers should benefit from our successes and grow from our Solutions.


Efficiency is the watchword of today’s competitive and globalised economy. We develop, demonstrate, manufacture highly efficient and innovative electric powered technologies for marine, stationary power, and mobile industrial machines.
