Oil-free, compact and lightweight hydrogen recirculation blowers

With our technology, we are able to design and build hydrogen recirculation blowers (HRB) with gas bearings. This key component can be applied to the hydrogen circuit in the anode path of a fuel cell and offers the following benefits:

• Shock and vibration proven technology
• Oil and contamination-free solution
• Wear- and maintenance-free operation
• Lifetime of several 100,000 start/stop cycles
• Capable of variable anode gas mixtures
• Ultra-high-speed motor enables small and lightweight design – ideal for integration
• Precise control of flow rates guarantees optimal control of stack conditions

Other applications include recirculation in electrolyzes and compression for transport and storage.
