Rotarex and LIST: A Partnership Built for the Future of Innovation

Targeting the hydrogen, microelectronics, and semiconductor sectors, ALDACIA addresses one of the most demanding challenges in surface engineering today, the reliable coating of complex internal 3D geometries at an industrial scale. As these industries impose ever-higher standards in terms of purity, reliability, and performance, conventional surface treatments are reaching their limits. ALDACIA represents a collective effort to move beyond the limitations.

Rotarex’s commitment to collaborative innovation is reflected in its continuous investment in research and development, with approximately 3% of its annual revenue reinvested in R&D. ALDACIA builds on a previous successful joint project with LIST focused on reducing gas pollution and marks a new step forward in a trusted and evolving partnership based on teamwork, knowledge sharing, and long-term vision.

“Working side by side with LIST, our teams are developing advanced coating solutions that directly support demanding hydrogen and semiconductor applications. I’m particularly proud as a woman engineer to lead a project where collaboration and expertise go hand in hand to break through technical barriers”.

ALDACIA directly supports Rotarex’s strategic positioning within the hydrogen and semiconductor markets, where valve performance is critical to the integrity of entire systems. More broadly, the project illustrates a shared conviction: the most advanced technological solutions emerge from strong collaborations and committed teams working together toward a common goal.
