The iSi System

iSi Chargers and Whippers have been developed as one system. 

Their technical details are therefore tailored to work perfectly together. This functional achievement is permanently checked using safety-related tests and quality assessments. The perfect function of your iSi Whipper can only be guaranteed if you exclusively use iSi Chargers with it!

Do not combine your iSi Whipper parts with those from other manufacturers as we cannot provide a guarantee for them. iSi heads are marked on the head and charger holder. iSi bottles are marked on the base. If you bear this in mind, nothing can stand in your way of achieving a perfect culinary result.

High-Tech Inside and Out

Thousands of iSi Whippers and Siphons are used in kitchens around the world every day. But what exactly goes on inside the bottles?

No Foam without Gas.

Nitrous oxide (N2O) generally dissolves much better in fat than in water meaning that liquids with a high fat content generate a much better foam in a siphon than low-fat liquids. However, fat-free liquids can be foamed using a binding agent. Originally cream siphons were developed for the production of whipped cream, which is an ideal liquid to aerate, due to its high fat content.

A Foam Takes Form…

In an iSi Whipper, soluble gas (usually nitrous oxide, also known as N2O, enclosed in the iSi Cream Chargers) is released into the liquid to be foamed with the help of pressure. The liquid is released by this pressure in the siphon through the tip, causing the dissolved gas to expand and the liquid to foam — a delicious Espuma is created! The iSi Whippers are technically perfected and are suitable for the preparation of Espumas, finger food, warm and cold sauces, foamed creamy soups, as well as whipped cream and desserts. The whipper bottles and heads are made of high-quality stainless steel, perfectly tailored for professional use in gourmet kitchens worldwide.
