Hydrogen - Schwer Fittings

Future with hydrogen

In the future, hydrogen will play a major role in the conversion of our energy supply. As a storage medium for ecological electricity and for mobility with fuel cell drives. When hydrogen is produced by electrolysis, water is separated into hydrogen and oxygen using regeneratively generated electricity. In a chemical process, the hydrogen reacts with oxygen. The energy stored in the hydrogen is released as electricity, which then drives an electric motor.

Our brand: H2-Lok

Schwer Fittings has fittings solutions for the total hydrogen supply chain, from Hydrogen generation, through storage to destribution and usage.

You can choose from various variants of screw connections and fittings, depending on the area of application and the need for certification according to EC79 for use in vehicles with hydrogen engines.

For example, we differentiate between the following screw connections that are suitable and approved for hydrogen applications:

Our fittings for your hydrogen applications

Clamping wedge ring and cutting ring screw connections are ideal for hydrogen applications as well as for gas applications. The wedge ring fittings are EC 79, DNV GL and TA-Luft certified, the cutting ring fittings according to DNV. The fittings are produced in our own European factories. Sensitive components, such as the clamping and wedge rings, are manufactured in the factory in Germany.
