Foam extinguishers cartridge operated CS-Series - Fluorine free foam in cartridge

SK6CS ECO, SK9CS ECO - Fluorine free foam in concentrate cartridge

Composite valve

The push button valve of the DÖKA CS series are made of fiberglass-reinforced composite materials. Metal inlets strengthen the fitting. The union nut is made of brass. The pressure resistance of the valve body far exceeds the values required by the standard.

The control elements of the CS series, such as the strike button, safety device and handle, are designed in such a way that the fire extinguisher can also be operated with gloves without any problems. The rotating extinguishing pistol rounds off the perfect handling.

The DÖKA cartridge operated foam fire extinguishers of the CS-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 SK6CS ECO and SK9CS 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.
