Oasis TH404 Hydrogen Valves
All existing valves are removed and replaced with bonfire-tested and approved Oasis TH404 models. New actuator arms with bronze bushings maintain electrical grounding.
520-Bar Hydrogen Trailer Retrofit
FASTECH-engineered and Industry approved, the 520-bar gaseous hydrogen (GH2) trailer retrofit improves safety and uptime. Converting legacy system into isolated vented vessels reduces risk while simplifying the operator experience.
High-Volume Hydrogen for Mobile or Permanent Fueling
FASTECH’s trailer retrofit swaps original parts for enhanced ventilation and easier end-use. Upgraded parts include all valves, storage vessel side skins, and thermal pressure relief devices (TPRDs).
Independent Vessel Control
If a valve needs repair, you can isolate its vessel and keep the rest of the system in service until the next maintenance check.
Safer Operation
New vent lines are dedicated to each TPRD and discharge at roof level, lowering the risk during over-temperature events.
Simplified Maintenance
No more full-system testing for every fix. Crews can repair the vessel and return the trailer to service faster.
Key Components
The FASTECH retrofit replaces older hardware with proven, service-friendly parts.
VTI certified Middle & End Plug
All existing TPRD are removed and replaced with bonfire-tested and approved VTI TPRD. Built for trucks and buses, these plugs support emission-free transport with proven reliability from over 20 years of VTI innovation.
Upgraded Vessel Structure Side Skins
Trailer side skins are replaced with non-combustible powder-coated aluminum. Upper skins are louver-punched to add ventilation.
The FASTECH Difference
The hydrogen trailer retrofit replaces high-pressure valve systems, thermal protection, and venting, allowing each vessel to be controlled and serviced independently.
The result is straightforward repairs, safer vent paths, and less trailer downtime.
The retrofitted trailers can serve as either mobile or permanent storage for H2 stations, feeding mobile fuelers directly or replenishing on-site storage.
