FOS - H2Refuel Fleet Owner Station
Safe. Cost-efficient. Maintenance-friendly.

Download datasheet

The H2Refuel Fleet Owner Station (FOS) is designed to provide fleet owners, governments, and entrepreneurs with a cost-efficient solution to hydrogen refueling of FCEVs with 350 and/or 700 bar. With its lean design costly components like accumulator storage and deep cooling of hydrogen prior to filling are avoided. The station concept is attractive for the development of a hydrogen mobility infrastructure requiring little capital investment when compared to full-sized stations. The FOS consists of three components: The compression compartment, the dispenser module, and the control panel. To warrant safe operation, this design allows for the separation of components from explosive areas close to the compression compartment. The Resato gas booster technology is integrated into the station to provide safe high pressure gas supply to the vehicle.

FOS Benefits and Features

FOS Benefits and Features
- Long seal lifetime based on dedicated engineered polymer compounds that are based on low-friction PTFE resins. - Lifelong lubrication during assembly avoids lubricated air lines and reduce maintenance on the booster. - Air drive section of the gas booster contains only a small amount of moving parts reducing wear and noise. - Guaranteed lifelong operation due to the check valves from ceramic materials. - Improved reliability and cycling speed due to the lack of mechanical pilot valves and long internal pilot channels. - Reduced cost of ownership and maintenance downtime because the high pressure seal can be replaced without dismantling the air-drive section. - Standard provided with vent holes to prevent gas from the high pressure gas section escaping to the air drive section. This ensures a safe operation. - The V-shaped expansion ring reduces preload and reduces frictional resistance making the booster more efficient for operation and maintenance.
