CO2 fire extinguishers - advice, installation & maintenance

Our CWS CO2 fire extinguisher uses carbon dioxide to extinguish small fires of fire class B quickly and reliably. It is suitable for fighting liquid or substances that become liquid (e.g. paint, tar, petrol) and is therefore frequently used in laboratories, electrical installations, EDP rooms, server rooms, switch cabinets, and clean rooms. CWS carbon dioxide fire extinguishers are officially tested and approved (DIN EN 3, GS, and CE).

The extinguishing agent is pressure liquefied carbon dioxide in high-pressure steel cylinders or, cooled at -20 °C, in large low-pressure containers. The CWS CO2 fire extinguishers can be used in the functional range from -30 °C to +60 °C. As carbon dioxide is not electrically conductive, unlike all water-based extinguishing agents and most powders, you can also use the CO2 fire extinguisher on electrical systems up to 1,000 volts.

The CO2 fire extinguisher is a continuous pressure extinguisher with a hand lever function. It can be purchased as a portable version with a floor stand or wall mount as well as a mobile version. All versions of the carbon dioxide extinguisher are ready for immediate use.

Please note: According to DIN 14 406, all fire extinguishers in commercial or public areas must be serviced at least every two years by a specialist such as CWS Fire Safety. For a better overview of maintenance times, you can use the digital fire protection file of CWS Fire Safety: Here you will find information about which fire extinguishers you own and when maintenance is due. CWS offers a relaxed all-in-one service: We supply, install, and maintain your fire extinguishers.
