Process Engineering

The best way to engineer a successful production?
The addition of knowledge!

In the field of process engineering, we assist our customers in all issues related to plant and equipment technology. Our support is based on the broad spectrum of knowledge of our engineers*, technicians* and technical specialists, who have diverse practical experience in physical, chemical, thermal and mechanical processes.

We replan process plants and equipment – from the concept study to the detailed planning up to the completion and start-up of the installation. And in addition to that, we take care of existing plants and optimise them in order to make them more efficient and profitable for our customers. You can also rely on our experience when it comes to fault analyses and safety assessments.
