WEKA Solutions for the Energy Revolution

International fusion research is working on the energy source of the future: ITER, tokamak and stellarator projects require complex cryosystems for superconducting magnets at -269°C, cooled radiation shielding and tritium handling under extreme neutron radiation. Plasma diagnostics and magnet coil cooling must function reliably for decades.

WEKA is a partner of international fusion projects with highly specialized components for large-scale research facilities – our ITER-qualified valves, radiation-resistant transfer lines and redundant safety systems ensure the operation of billion-dollar investments. From Wendelstein 7-X to JT-60SA, fusion centers trust our proven technology.

Expertise for Extreme Research Conditions
In plasma and fusion research, precise cryogenic solutions are indispensable for scientific success. Cooling of superconducting magnets is an important driver for cryogenic systems and distribution networks. The cold fluid must be efficiently distributed across the entire experimental site so that cooling takes place where it is needed.

For Research Environment
Liquid helium at temperatures just above absolute zero is usually used as cooling medium, with highest attention paid to minimal heat losses. 
Besides process parameters, additional boundary conditions such as magnetic fields or neutron radiation must be considered in valve design.

Our control and shut-off valves are available with pneumatic, electric, or manual actuators. Check valves, safety valves, transfer line couplings, and ejectors belong to the broad range of our superconducting magnets helium solutions for this sector.

The extensive experience gained from numerous optimally solved cryogenic challenges in plasma and fusion research forms the solid foundation for mastering future challenges in international cutting-edge research.

Specially developed designs minimize heat ingress and ensure stable operating conditions even under the most extreme research conditions. Magnetic field-resistant materials and radiation-resistant components ensure long-term reliability.
