Aqueous solution

The extinguishing effect is based on the heat binding capacity (heat capacity) of the water. The seat of the fire is cooled down considerably and the combustion is stopped. The extinguishing agent consists of water with and the addition of salts. This means that our water fire extinguishers are frost-proof down to -30 ° C. The extinguishing agent is completely free of PFOS and PFOA.

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.
