Founding history

In 1999, Marcel Kohler realised a long-cherished dream and started developing a new generation of cryogenic pumps – patented and customised for optical application. After successful completion, they were positively welcomed by the international market. This success led the long-serving development manager of the former Balzers AG to found HSR Kryotechnik AG together with Herbert Vogt in 2001.
Two years later, the owners extended the company’s product range. They took over the business area “Diffusion and UHV pumps” from Inficon (once Balzers Instruments) in Balzers and gave the company the name which it holds today.


With the takeover of a further business area from Inficon in May 2008, HSR AG was able to add plate valves and angle stop valves to its product range.
