WEKA AG is a leading manufacturer of Cryogenic-Components for the application of liquefied, cryogenic gases.

Cryogenic respectively cold comes from the Greek word Kryos. Generally "cryogenic" refers to the temperature range below about 120K (-153 ˇăC); download TempScale.pdf (15 kb).

However WEKA Cryogenic Components are mostly used in cryogenic processes below about 70K (-203 ˇăC).

Cryogenic technology is used for cooling of superconducting solenoids and acceleration cavities in high energy physics and in fusion research. Cryopumps generate ultrahigh vacuums. Liquid hydrogen is used as fuel for rockets and more and more as energy source. Cryogenic distillation processes are used for the production and storage of Helium and Hydrogen as well as for Oxygen, Nitrogen and Argon.
.
Due to its physical properties Helium (He) in the gas, liquid or suprafluid state is the most used cooling fluid with WEKA Cryogenic Components. The normal boiling point of Helium is 4.2K.

Also used are WEKA Cryogenic Components with gases like Oxygen (O2, normal boiling point at 90K), Argon (Ar, normal boiling point at 87K), Air, Nitrogen (N2, normal boiling point at 77K) and Hydrogen (H2, normal boiling point at 20K) as well as for rare gases like Xenon (Xe), Krypton (Kr) and Neon (Ne).
