Hydrogen energy and its significance for the future

Hydrogen energy is considered one of the most promising solutions for a sustainable and emissions-free future. As a clean energy carrier that releases only water when burned, hydrogen has the potential to replace fossil fuels in numerous applications. From power generation to the transportation sector and industrial use, the possibilities are vast, and they play a key role in reducing greenhouse gas emissions.

Our company is making a significant contribution to this green revolution. With over 60 years of experience in cutting ring technology and our own manufacturing, which has enabled hydraulic applications worldwide for decades, we are well-equipped to meet the challenges of the hydrogen economy. Our specially developed hydrogen fittings ensure the highest safety and efficiency in handling hydrogen, making us an indispensable partner on the path to a carbon-neutral future.

Through our innovative solutions and long-standing expertise, we actively contribute to turning the vision of a sustainable energy future into reality.

Reliable Connections for Highly Sensitive Applications

Hydrogen is a highly sensitive and volatile gas, which makes it particularly challenging to handle and store. Due to its small molecular size, hydrogen can easily escape through the tiniest cracks and leaks. Additionally, hydrogen is highly flammable and can form explosive mixtures when combined with oxygen. These properties require the highest precision and reliability in all components that come into contact with hydrogen.

Therefore, it is of utmost importance to use reliable fittings in all products and systems of hydrogen technology. Our cutting ring fittings provide exactly this safety and reliability. They ensure leak-tight connections and prevent hydrogen from escaping, which is crucial for both the efficiency and safety of the entire hydrogen infrastructure.

  • Hydrogen Filling Stations: In the complex piping systems of hydrogen filling stations, our fittings ensure safe and reliable connections. They are essential for fueling hydrogen vehicles and ensure leak-tight and safe handling of the gas.
  • Hydrogen Trailers: When transporting hydrogen in special trailers, our cutting ring fittings provide the necessary stability and leak-tightness to ensure the safe transport of the highly flammable gas.
  • Hydrogen Storage Systems: In pressure tanks and other storage media for hydrogen, our fittings ensure secure and durable connections. This is particularly important to avoid leaks and maintain the integrity of storage containers.
  • Electrolyzers: In hydrogen production through electrolysis, our cutting ring fittings are used in the piping systems. They secure the connections between the various components and contribute to the efficiency and safety of the entire process.
  • Compressors: In hydrogen compressors, which compress the gas to high pressures, our fittings are crucial for the safe handling of high pressures and preventing leaks.
  • Fuel Cells: In fuel cell systems that use hydrogen for power generation, our fittings ensure the reliability of the systems. By using our cutting ring fittings in these critical products and systems, we play a key role in the advancement and safety of hydrogen technology.
