Designed for 70 MPa hydrogen applications, GFI’s internal tank solenoid technology enhances durability and reliability by mounting the solenoid inside the tank. This design protects it from external impacts, environmental exposure, and corrosion while also resolving structural challenges by placing it within the pressurized space.
A temperature sensor is integrated within the tank to provide fuel dispenser feedback and improve fuel gauge accuracy.
