The engineering teams from Neuman & Esser and Festo worked together very closely to develop the solution. Each component of the explosion-proof design was tested, optimised, and validated for practical operation. The shortened development time and resulted in a solution that now serves as a reference for future PSA projects in hydrogen applications. Thanks to its modular architecture, the concept can easily be adapted to other systems and processes, thus providing a scalable basis for safe, digitally connected automation across the hydrogen value chain.
