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.
