Hydrogen Dispenser

Summary
The Hydrogen dispenser is the core equipment for the transaction settlement in the hydrogen filling station, which has high requirements for the accuracy of measurement, equipment stability and explosion-proof safety. The hydrogen dispenser designed by our company has safety protection fu nctions such as overpressure protection, ambient temperature compensation, pull off valve protection and leakage alarm system, which can automatically, energy-saving, safe, fast and reliable hydrogen filling for the vehicle fuel hydrogen bottle. It mainly includes high pressure pipeline, valve, filter, flow meter, hydrogen gun, electric control system and so on.
