Products / Applications Certificates References

A pioneer in the field of alternative fuelling components, WEH® provides high pressure hydrogen components that meet the highest demands, ranging from fuelling nozzles, breakaway couplings and filters for hydrogen fuelling stations through to receptacles and check valves for fuel cell vehicles.

The latest generation of fuel cell powered electric cars as well as hydrogen fuelling stations worldwide are equipped with fuelling components by WEH. Whether it be Europe, North America or Asia, fuelling of hydrogen fuel cell vehicles takes place almost exclusively with WEH components.

In view of upcoming global challenges, WEH strives to develop future-oriented product solutions for alternative energies. Thanks to intensive research and continuous further development of the product range, WEH is not only a reliable and highly appreciated partner for this type of cutting-edge technology, the company is also a trendsetter for a mobile future society.

WEH’s unique product innovations succeed to meet the high demands of the market and they are used for a diverse range of applications. The French train manufacturer Alstom presented the world’s first hydrogen powered train in 2016. This train is equipped with WEH® TN1 H2 Receptacles. Even forklifts can be powered by hydrogen nowadays. Since the initial introduction of hydrogen powered forklifts, WEH components have been used in millions of fuelling processes. Components by WEH® can easily handle busy activity with thousands of fuelling processes a day, and they have been adjusted to meet country-specific requirements, for example for Japan and the US. Furthermore, 700 bar technology allows for all types of vehicles to be fuelled within just a few minutes. WEH is going to continue to develop cutting-edge products, in the future. WEH’s new 70 MPa Fuelling nozzle with an integrated display and start button, featuring an innovative and inimitable design will be introduced to the market in 2019. This product is going to revolutionise fuelling processes.

Products / Applications

WEH® TK17 H2 70 MPa

WEH<sup>®</sup> TK17 H<sub>2</sub> 70 MPa

First pistol grip fuelling nozzle for hydrogen
For the first time, a hydrogen nozzle in the pistol grip style has been developped for refuelling of cars with compressed hydrogen (CGH2). The nozzle is just as quick and easy to use as a common petrol nozzle: lift the nozzle from the dispenser and place it onto the vehicle's receptacle.
Gaseous hydrogen can only flow through the line if there is a safe connection. Extremely high flow rates result in short filling times. After refuelling disengage the nozzle's locking lever and disconnect.
The WEH® TK17 H2 70 MPa has a coding for pressure range and gas type that will not allow connection to natural gas vehicles or other pressure ranges. The TK17H2 70MPa is certified according PED97/23 (designed and tested according SAE J2600:2002 and SAE J2799 TIR as applicable). The TK17 H2 70MPa is also available with KHKS certification.

WEH® TSA1 H2 70 MPa

WEH<sup>®</sup> TSA1 H<sub>2</sub> 70 MPa

Enhanced safety for Hydrogen Fuelling Stations
In the event of accidental deployment by driving a vehicle from a filling station with the nozzle attached to the vehicle fuel port, the TSA1 H2 70 MPa will safely separate the connections between dispenser and filling hose. Both ends become instantly sealed, preventing an escape of gas.
The whole dispensing system is protected against damage , costly station downtime is avoided. The TSA1 H2 70 MPa is the first hydrogen breakaway with an integrated, maintenance-friendly 20 micron particle filter.
The TSA1 H2 70 MPa is rated for 700 bar refueling and a separation force of 300 to 600 N and is optionally available with IR-cable. The breakaway is certified according PED97/23.

WEH® Coalescing TSF2 H2

WEH<sup>®</sup> Coalescing TSF2 H<sub>2</sub>

Hydrogen free of impurities with WEH® TSF2 H2 Coalescing Filter
Clean, filtered gases are essential to guarantee the proper function of components for vehicles and filling stations when refuelling with hydrogen. No problem for the new WEH® type TSF2 H2 coalescing filter. TSF2 H2 filters the gas flow and removes contaminants reliably.
The WEH® TSF2 H2 has a high particle removal efficiency (efficiency of approx. 99.9% > 0.3 micron) in order to protect the critical components in the fuel system. Designed for installation onboard hydrogen vehicles (EC79) and in fuelling stations (CE). It is constructed of high grade material and easy to maintain.
WEH offers a wide variety of particle filters for various applications and end configurations, e.g. double ferrule fitting or internal thread on both sides, internal and external thread; T-Filters for hydrogen busses and trucks, etc.

WEH® TN1 H2 70 MPa und WEH® TVR1 H2 70 MPa

WEH<sup>®</sup> TN1 H<sub>2</sub> 70 MPa und WEH<sup>®</sup> TVR1 H<sub>2</sub> 70 MPa

Hydrogen receptacles and check valve
WEH completed its product range for 70 MPa hydrogen refuelling by developing the TN1 H2 70 MPa receptacle the TVR1 H2 70 MPa check valve for installation in light duty hydrogen vehicles. The WEH® TVR1 H2 70 MPa has a check valve system designed to minimize the effect that dirt particles have on sealing components within the valve. Also the WEH® TN1 H2 70 MPa has an integrated non-contact high-flow check valve ensuring the same effect. Both, the TN1 H2 70 MPa and the TVR1 H2 70 MPa are very durable units, minimizing maintenance and downtime. The sleek internal aerodynamic design gives low noise combined with a maximum flow rate and fast filling. A particle filter 20 micron integrated in the WEH® TN1 H2 70 MPa receptacle protects the system from impurities in the gas flow (optionally available without particle filter). Also the check valve WEH® TVR1 H2 70 MPa is optionally available with particle filter.
The receptacle has a coding for pressure range and gas type that will not allow connection to CNG fuelling nozzles or nozzles to other alternative fuels. The WEH® TN1 H2 70 MPa is approved according to EC79/2009. The WEH® TVR1 H2 70 MPa has an approval e1 for cars and is appropriated for installation in hydrogen fuelling stations (CE).
