Foam extinguishers cartridge operated DS-series - Fluorine free foam in cartridge

SK6DS ECO, SK9DS ECO - Fluorine free foam inconcentrate cartridge

Composite valve and universal handle

The  valves  of  the  DS-series  are  made  of  glass  fiber reinforced composite materials. Metal inlets additionally  reinforce  the  fitting.  The  cap  nut  is  made  of  brass.  The  new  design  of  this  series  of  valves  enables the fire extinguishers to have a lower overall height. Thanks to the extra large, ergonomic handle, the fire extinguisher can be easily carried over a long period of time. A  non-rotating  safety  device  enables  the  fire  extinguisher to be operated even faster and also has a rotating extinguishing pistol.

The DÖKA cartridge operated foam fire extinguishers of the DS-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 SK6DS ECO and SK9DS 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.
