Conceptual Design
Special tasks sometimes require unconventional solutions. We love problems and see them as challenges that stimulate our creativity. As a guiding principle, we always focus on the best possible system behavior of a powertrain in terms of overall efficiency and emissions. When we break this down to the central element of the air supply for an internal combustion engine or a fuel cell, we are also happy to venture beyond known approaches to come up with new ideas – which often puts us one step ahead. The implemented solutions are then tested and validated. This concept phase expresses the quintessence of our engineering work, in which we fully express our competencies in the optimization of overall system behavior.
Layout and Design
Building on our solid conceptual basis, we lay out the charging, air supply and energy recovery systems that have been broken down into their individual components such as compressor and turbine stages. Our focus is on the operating behavior of the overall system, whether it is a small supercharged gasoline engine or a (highly) supercharged fuel cell. One of our core competencies is finding the best match between turbocharger system and internal combustion engine or fuel cell drive. We also – completely independently of commercial providers – lay out and design test benches and subsystems used for testing and validation, tailoring them to the respective requirements.
Prototyping
The core of our philosophy is the greatest possible vertical integration of our in-house manufacturing capabilities, especially where it can be decisive for achieving project goals. This is also the case when it comes to testing and validation. We not only develop our test benches, result-critical instruments and all test bench adaptations in-house, but we build most of them ourselves, too. This applies both to solutions for our internal use and to products we sell to third parties. Our Swiss location is particularly advantageous when it comes to producing turbocharger components and complete turbocharger prototypes. Numerous companies located in the greater Baden area are familiar with the specific requirements of turbomachinery manufacturing.
Core Competencies
Our expertise lies in how we connect profound turbomachinery knowledge, turbocharged engine system analysis, and well-established methodology.

Variable Venturi
Correctly determining the mass flow is essential for thermodynamic evaluations on the turbocharger test bench.

Testing
The precise assessment of turbomachinery’s thermodynamic and mechanical properties is another of our core competencies and represents an important pillar for efficient development work on turbochargers and air supply systems. We have 4 hot gas test benches at our facility in Mellingen, Switzerland for testing turbochargers and energy recovery systems. Developed in-house, they are based on our decades of experience and are recognized in the industry for the robustness and reproducibility of their results. We developed a specific test bench for assessing air supply systems for fuel cells and energy recuperation systems based on turbines.
