Your product and development partner

Energy demand and the importance of electricity as an energy source are increasing worldwide. Energy production and distribution are in a state of upheaval. Wind and solar energy are steadily gaining in importance. Grid security, volatility in the availability of renewable energy and the proliferation of small, decentralised energy systems pose new challenges for the industry.

We provide smart products and technologies for the energy sector. SERTO components and systems can be found in wind turbines, solar power plants and inverters. The cooling of power electronics and the generation and conversion of hydrogen are important fields of application. The variety of materials and products as well as many years of experience in system design and system optimisation make SERTO your perfect product and development partner.

Discover the wide range of our products and the variety of our materials

Our tube union components have specific properties for applications in the energy sector. And we also provide additional services.

  • Resistance to changing external influences (temperature, air composition, humidity)
  • PVDF, which is non-electrically conductive and high-frequency stable, for cooling with ultrapure water or water-glycol mixtures
  • PVDF manifolds
  • Stainless steel for applications subject to thermal loads
  • Aluminium for cooling plates



Hydrogen and fuel cells are regarded as key energy sources on the way to a global emission-free future for climate-neutral industrial production, heat generation and mobility.

Hydrogen can penetrate even the smallest openings. Pipelines for the small-molecule gas must therefore be made of suitable materials and fitted with components that are highly leak-proof.

Gas tightness and leakage resistance are the two most important performance criteria for fittings. We offer clever products and technologies for all applications in the hydrogen industry.

The SERTO Group offers several ranges of fittings made of high-quality stainless steel in various grades. EXMAR and SERTO components and systems can be found in electrolysers, fuel cells and H2 sensors.
