Foam extinguishers cartridge operated BS-Series PREMIUM LINE - Fluorine free

Si6BS ECO - Fluorine free foam

Brass valve and safety device for the highest demands on quality and safety

The DÖKA cartridge operated fire extinguishers of the BS series are equipped with a high-quality push button valve and cap nut made of nickel-plated brass. In addition to the standard, the BS series is also equipped with an additional pressure relief valve with a brass body, which protects the cylinder from excess pressure. The generous dimensioning of the safety device and strike button enables the fire extinguisher to be operated with gloves. The ergonomic handle with finger recesses and slip protection offers excellent carrying comfort. The rotating extinguishing pistol enables optimal control of the extinguishing agent jet and the operation of the fire extinguisher with just one hand.

The DÖKA BS series is the highest quality equipment variant of our rechargeable fire extinguishers. High-quality materials, the ergonomic design and the extensive selection of different types of fire extinguishers. We offer frost-proof wet and grease fire extinguishing agents as well as special extinguishing devices exclusively in the BS series. The PREMIUM LINE for the highest demands on quality, reliability and safety.

The DÖKA cartridge operated foam fire extinguishers of the BS-series with internal propellant cartridge. The fire extinguisher is only put under operating pressure after pulling the securing and depressing the push button when it is in use. This ensures a high level of operational reliability, saves material and minimizes maintenance costs.

Fluorine free foam

In the development and manufacture of fire extinguishers, questions of environmental protection and resource conservation are always the focus of attention. It is important to combine environmentally friendly technologies as well as safe and highly functional operational capability. The DÖKA Si6BS ECO is the first fluorine-free foam fire extinguisher with 9 extinguishing agent units.

In recent years, foam has become the most important extinguishing agent in the field of portable fire extinguishers. The significantly lower damage caused by extinguishing agents during use, compared to powder fire extinguishers, has made it indispensable, especially in indoor areas.
In order to achieve an acceptable extinguishing performance, it was not technically possible up to now to completely dispense with the use of fluorine. Thanks to the new formulation of the foam extinguishing agent used in the Si6BS ECO, it has now been possible to achieve the rating of 27A / 144B and thus almost the performance of conventional foam agents.

The Si6BS ECO is based on the sophisticated device technology of our foam extinguishers. Neither special foam nozzles nor special propellant gas cartridges are required. Environmentally conscious and economical, especially when it comes to service.

Quality features

Push button valve made of brass - only in the BS series

The body of the push button valve is made of nickel-plated brass. All other components such as hose, riser pipe, blow pipe and propellant gas cartridge are mounted on the base body. Nickel-plated brass is significantly more resistant to extinguishing media and environmental influences and therefore more durable than plastic fittings. For this reason we only offer certain device versions in the BS series, such as frost-proof water and foam extinguishers. We also offer fire extinguishers with MED approval, i.e. for use on ships, only in the BS series.
