Dynameco fire extinguishing generators, the innovative and environment-friendly suppression technology.
The Dynameco aerosol fire extinguishing technology is based on a pyrotechnical extinguishing charge. In case of a fire, this extinguishing charge is ignited electrically, thermally or manually.
The pyrotechnical extinguishing charge consisting of potassium nitrate and nitroguanidine is caused to react. The chemical reaction generates potassium carbonate, which flows through a cooling area along with the simultaneously generated reactive gases and then out of the openings at the bottom of the extinguisher, emerging into the environment as a fine aerosol.
The average particle size of the aerosol is between 0.5 and 2.5 μm. The extinguishing effect of the aerosol or the potassium carbonate results from the combination of a physical and a chemical process.
The ionisation in the flame withdraws energy from the combustion process. Free radicals in the flame are bound by the potassium carbonate, thus stopping the chain reaction. The extinguishing principle, therefore, is not based on the removal of the oxygen important for combustion or on cooling, as is the case with other fire extinguishers, but on the principle of interruption of the oxidation process at the molecular level.
