On May 14, 1964, the foundation for the brand name and logo for today’s iSi Group was laid with the listing of the iSi Metallwarenfabrik GesmbH.
Since then, innovative strength and research have been the factors for success behind our international market leadership in pressurized gas systems. Today, the iSi Group is present worldwide with production and sales facilities, selling products to more than 80 countries. We provide customized solutions for all applications in which compact energy is required in the form of pressurized gas chargers.
iSi began as Karl Fischer-Pochtler GmbH. In the early 19th century, it was already producing the first soda machines under the company name Carl Pochtler AG. The CO2 chargers used for making soda water and the N2O chargers for creating cream, soups, sauces, and foams make up the core product of the company's Culinary division.
The company is still family-run: Christian C. Pochtler is a direct descendant of the Fischer-Pochtler family. He has successfully led the company into the 21st century with an innovative business strategy.
