Years of experience, innovation, and the highest quality. That's how standards are set.

iSi  represents the highest level of quality around the world. This is just as true for charger production as it is for the manufacturing of cream and soda siphons. Years of experience drive iSi to continuously set new standards. Its Vienna site produces chargers and whippers which meet the highest international demands in terms of technology and quality.
iSi Whippers are used throughout the world, in award-winning professional kitchens, gastronomy, catering, and in private households. Wherever they are used, they help to make work easier and create inspiring dishes.

iSi Charger Quality

iSi is certified by the BUREAU VERITAS under ISO Standards 9001:2015, 14001:2015 and SA8000:2014. These standards guarantee consistent high quality. In order to ensure the highest possible level of product safety, every single charger can be traced throughout its life cycle.

Each charger contains approx. 8 g gas, pure N2O in the cream charger and CO2 in the soda charger. The charger shell is made of high-quality, 100% recyclable, pure steel. Each iSi Charger has a filling warranty. It is easy to differentiate between the iSi Chargers externally; The iSi Cream Chargers are silver and the iSi Soda Chargers are gold.
iSi Chargers and iSi Whippers are tailored to work perfectly together. The perfect function of your iSi Whipper can only be guaranteed if you exclusively use iSi chargers with it!
All iSi products are subject to strict safety and quality standards. They comply with the following EU Directives and Standards:

  • EC Directive no. 1935/2004
  • EN 10/2011 and
  • all current national standards


Hazard Analysis and Critical Control Point is a system that was developed for NASA. It combines strict guidelines and inspections in order to ensure the safety of food products. For example, companies are obliged to analyze and resolve possible critical issues. As cream, soda, and beer chargers are classified as food products, the iSi production process is certified on the basis of a HACCP concept.
