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 TÜV Süd under ISO Standards ISO 9001:2015,  ISO 14001:2015 and HACCP.

The requirements of HALAL and NSF are embedded in our IMS.Production is regularly checked by the HALAL Control Organisation and the conformity of production is confirmed through certificates. Additionally, our devices comply with FDA regulations and are listed with NSF International.

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:

  • EU Guideline Nr. 1935/2004
  • EU Guideline Nr. 10/2011


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.

ISO Certifications


Truly sustainable development is only possible with our employees and environmental awareness.

From the Raw Material to the Charger

The raw material used to produce iSi chargers is deep drawing steel. This metallic alloy is supplied in large rolls and processed in our own production department. 
The steel is turned into our chargers, which must meet the highest quality requirements each step of the way. iSi is certified under ISO 9001:2008, ISO 14001:2004, and HACCP by TÜV Süd.

Steel shavings and other high-quality scrap and waste are not discarded during the production of the chargers. We deliver this waste to steel plants for further processing, so new steel can be produced from the scrap and waste.

Special Protection for the Employee

iSi GmbH aims to maintain a culture of integrity and compliance and to take into account the needs and expectations of interested parties in this regard. This is based on binding and voluntary commitments - for iSi GmbH these specifically include the CSR "Corporate Social Responsibility" aspects to which the company has been committed since 2011. These include, among other things, the social protection of our employees (safe and pleasant working environment for the employees, workers and labourers) and the inclusion of our suppliers, who have already joined our management paradigm with the "Code of Conduct".

REiNTEGRA – Social Responsibility In Action

Since 2007, iSi has put its faith in employees from the industry and trade group REiNTEGRA, a charitable organization based in Vienna that aims to reintegrate mentally ill people back into working life. REiNTEGRA is one of the largest rehabilitation organizations in Europe.

Since it was founded in 1982, REiNTEGRA has been caring for and supporting mentally ill people when they join or rejoin working life in order to get them used to work-oriented daily routine again, depending on their individual talent and inclination. Since then around 4,000 patients have been employed, around 28,000 orders have been successfully processed and more than 2,400 clients have been assisted. REiNTEGRA is therefore also a contact for companies who want to give mentally ill people an opportunity. In this area, iSi is a pioneer in terms of the manner and extent of cooperation with REiNTEGRA and has already been integrating the patients into an ordered and meaningful working life for more than six years.

REiNTEGRA has put together a team of qualified employees for iSi who, under the guidance of rehabilitation staff, put the finishing touches to iSi products and then carefully weigh them, pack them and carry out visual inspections of them at the company headquarters. After starting out with 13 employees, today there are already 35 people working for iSi as part of this project. The employees from REiNTEGRA pack around 50,000 bottles and replacement part sets, check and weigh around 90,000 chargers and pack around 700,000 chargers per month for the iSi Group. The employees are known at iSi for their 100% accuracy, reliability and focus on work, and therefore they are a permanent and pleasing part of the staff.

Our Chargers as Climate-Neutral Packaging

The ARA climate certificate is a recognition for responsible companies like iSi, which make an active contribution to climate protection by releasing their packaging to ARA AG. 
The release of packaging material is not only "climate neutral" but, as a result of the collection and use of packaging, also results in an active reduction of environmental impact. 
The climate certificate shows that we make a valuable contribution to climate protection.
