The breakaway coupling type TSA1 H₂ 70 MPa offers additional safety for your fuelling station. The coupling consists of a breakaway coupling and a receptacle which are installed between the dispenser and the fuelling hose. 

In the event of accidental deployment, e.g. driving a vehicle from the dispenser with the nozzle remaining in the vehicle fuel port, the coupling will separate, sealing both ends and protect your dispensing equipment against damage. The detached coupling can be easily reattached and placed back in service after having been function tested. 

The integrated filter system provides clean hydrogen and is easy to maintain.

A new Inline break-away coupling type TSA2 H₂ is now available, which is installed inbetween the filling hose. 

In the event of accidental deployment, e.g. driving a vehicle from the dispenser with the nozzle remaining in the vehicle fuel port, the coupling will separate, sealing both ends and protect your dispensing equipment against damage. 

The detached coupling can be easily reattached and placed back in service after having been function tested.

Dirt particles in the hydrogen fuel may cause damage to the sealing components whilst refuelling. The WEH-Filters are designed to capture dirt and gas-borne debris thereby reducing the danger of errosion. 

Type TSF4 H₂-SPECIAL has been designed for use in hydrogen buses. The filter can be removed for cleaning purposes without disconnecting of the media lines.

WEH have high-pressure hoses with recirculation lines to suit WEH-Fuelling nozzles type TK16 H₂, TK17 H₂ and TK25 H₂. The high-pressure hoses are available with the appropriated fittings. 

The high-pressure and venting hoses can be delivered in different standard sizes. Special sizes and terminations are available on request.
