Prothelis stands for reliable technology and high-quality design – made in Germany. We attach great importance to regional partners such as Herrmann Ultraschalltechnik GmbH & Co. KG or W. Kolb Manufacturing Technology GmbH. They allow us short distances and thus a high impact on production.

In order to ensure quality and thus promote sustainability, we have decided to produce our products under the following criteria:

  • Own development
  • Own conception
  • Own quality assurance

Tight quality controls control and secure the highest product requirements. We also want to promote the regional economy and create jobs on the ground under fair conditions.

With well-equipped workshops and laboratories, Prothelis offers the opportunity to develop all the prototypes on site. This allows ideas or optimizations to be implemented in a timely manner. We have a young research and development department working with technical colleges.

Every year we award several scholarships to the promising young researchers and in return are funded by the Ministry of Innovation, Science and Research of the State of North Rhine-Westphalia through the project promoter Jülich.

Our corporate policy is focused on long-term customer relationships and continued business success. We are constantly meeting the current market requirements. By continuously optimizing our processes and products, we ensure product quality and customer satisfaction, which is paramount. That’s why we decided to certify 9001. In doing so, we ensure success for our company, our employees and our customers.
