We are picky - and proud of it!

To ensure that large systems all over the world function safely and smoothly, our employees take care of every little detail, pedantically, fussy, meticulous - typically Swiss. 

The corporate film makes it clear: these are the skills that have made WEKA AG the market-leading manufacturer of cryogenic components for use at extremely low temperatures. Because thanks to this "Swiss precision", customers from the oil, gas and petrochemical industries, the chemical and pharmaceutical industries, as well as from shipbuilding and space research, receive precisely the products that make their operations safe and reliable.  

Insights and views of the inspiration behind our work are also shown – volume up and action!
