Wet chemical extinguishers permanent pressure Bio+ Fluorine free

Fire classes ABF - Suitable for lithium-ion-batteries - Fluorine free

Economy line

The DÖKA permanent pressure water fire extinguishers are equipped with an extinguishing agent cylinder made of quality sheet steel. The high-quality outer polyester resin coating is tough and weatherproof and protects the extinguishing agent container from corrosion. Inside, the extinguishing agent container is protected from corrosion by a thermoplastic polymer inner coating. The metal fitting with pressed brass body is equipped with a pressure gauge and a separate test valve

Fluorine free foam

The grease fire extinguishing agent Berki Cold is the first that is 100% biodegradable and free of added fluorine, PFOS and PFOA. It is not aggressive and not harmful to humans, animals or the environment. The fire extinguishers of the Bio + series are the alternative for environmentally conscious users.

Also suitable for fires involving lithium-ion batteries

Burning battery cells reach temperatures of up to 1000 ° C. Pure water would suddenly evaporate (delayed boiling) and could seriously injure people nearby. The extinguishing agent Berki Cold binds evaporating water molecules and thus effectively protects against scalding.
