In 1895 Dr Carl von Linde invented a process for the liquefaction of air and various gases, thereby ushering in the era of the cryogenics industry. As early as 1932, Linde supplied the world’s first industrial helium liquefaction plant to the University of Kharkov in the Ukraine. Initiated by the purchase of the Kryotechnik department of Sulzer, Winterthur in 1992, Linde decided to concentrate its low-temperature activities.

Linde Kryotechnik AG was formed from this merger and is located in Pfungen, Switzerland today, where about 100 highly specialized employees are developing cryogenic systems. In the intervening years, more than 600 systems have been successfully installed worldwide.
