SK6BS ECO, SK9BS ECO - Fluorine free foam in concentrate cartridge
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 concentrate cartridge
In foam cartridge fire extinguishers, the foam concentrate is separated from the water; it is stored in a cartridge. The foam concentrate and water are therefore not mixed until the propellant gas cylinder is opened in the event of use.
By storing the foam concentrate in the cartridge, it does not come into contact with the other extinguishing liquid. This results in a considerably longer shelf life of the extinguishing agent and consistent extinguishing performance over the period of use. The foam additives of the latest generation in our foam cartridge fire extinguishers contain no fluorine and are used only in very small quantities.
Fluorine-free foam additives, long shelf life and easiest disposal for a clean environment.
The fire extinguishing agent foam is produced from a water/foaming agent mixture by admixing air. For fires of solid materials (fire class A), the high wetting effect combined with the interruption of the gas exchange and the cooling effect are the main reasons for the excellent extinguishing properties. Foam extinguishing agents act by covering the entire surface of flammable liquids with a vapor-tight foam blanket, which prevents oxygen from entering (sticking effect) and cools the surface (cooling effect).
Why fluorine-free foam?
There are plans to completely ban fluorine in fire extinguishing agents or to place their use under heavy regulation. The exact wording of the ECHA (European Chemicals Agency) remains to be seen. It is also not yet clear when this ban will be implemented and what the transitional periods will be.
The SK6BS ECO and SK9BS ECO, with the latest generation of foam extinguishing agents, already do not contain any harmful fluorine and thus meet the upcoming requirements for a clean environment.

- Fluorine free foam
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.
The safety valve is installed according to the requirements of the DIN EN 3 standard. It is a spring-loaded pressure relief valve, which releases any impermissible operating pressure and closes it again, thus protecting the container. This means even more security for the user. The safety valve is also mainly made of brass.
The large, ergonomically shaped handle for easy handling of the fire extinguisher. The recessed grips and the curve at the end of the handle prevent your hand from slipping. The handle is big enough to be able to carry the fire extinguisher comfortably even with gloves. For stability and durability, the solid handle is made of fiberglass-reinforced plastic and is attached to the base plate with a stainless steel grooved pin.
The cap nut, like the base plate, is made of nickel-plated brass. It is equipped with pressure relief grooves through which the possibly pressurized extinguishing agent container can be safely depressurized by an expert. There are four cams on the nut for easy opening of the fire extinguisher, for safe, ergonomic use of the tool during service.
The extinguishing agent cylinder made of high-quality sheet steel is provided with a very high quality, resistant polyester resin coating that reliably protects the cylinder against corrosion.
The label is applied using a modern, high-quality screen printing process. The operating screen of the fire extinguisher is printed in two languages, German / English. Large, easy-to-interpret pictograms enable the fire extinguisher to be operated quickly and easily. The warning notices are printed inverted for better perception.
A footring made of impact-resistant HD-PE is used to protect the bottom of the Cylinder and for improved stability. The foot ring is simply placed on the cylinder and can be removed non-destructively for service purposes. A holder for the hose line is integrated in the stand ring and ensures that the fire extinguisher looks attractive.
The high-quality hose is made of durable EPDM synthetic rubber material. Fabric inserts increase the stability and pressure resistance of the hose line. A nickel-plated brass grommet is used for the hose connection to the fitting, which is firmly pressed to the hose line.
Flexible even in the cold - the hose is still flexible even in extreme cold and does not break.
The extinguishing pistol can be freely rotated 360 degrees, which means much more comfort and safety for the user. The large lever enables very good extinguishing agent dosing. The extinguishing pistol has a patented safety valve effect - if the pressure is too high, the pistol opens automatically, which means that the pistol cannot burst.
