TECHNOLOGY AND TRENDS Misting at high Pressure Fire extinguishing systems must do one thing in particular: extinguish fires quickly and reliably. For this purpose, there are methods that are tested and effective for decades, e.g. sprinkler systems. Next to a sole extinguishing performance, there are also increasing demands that the systems are resource-conserving as well as less environmentally harmful and offer further benefits. High-pressure fine spray extinguishing systems are presented from this point of view.  Günter Knopf Fig. 1: Nebulisation by the fine spray extinguishing system All photos: Günter Knopf Over the past years, many methods have been developed that fight fires using different extinguishing effects or prevent a fire from starting in the first place. Next to the cooling and smothering effects of conventional extinguishing agents such as water, foam, gas and powder, new methods are being used today that are even more effective in the cooling or smothering effect or that lead to molecular chain termination reactions. Another benefit of this new system is their low resources requirement. The high and low pressure fine spray extinguishing methods have, e.g., only approx. 10 to 15 % of the water requirement of a conventional sprinkler system and offer an additional smothering effect. These new extinguishing methods nd their extinguishing effect are listed in the table on page 23. Further extinguishing methods are currently in the development phase and will enrich the extinguishing system market in the future. From the abundance of the new extinguishing methods, we will give a more detailed description of the high-pressure fine spray nozzle extinguishing system here. A highly effective fire extinguishing method that achieves a very high extinguishing effect with relatively limited effort. This procedure originally comes from the shipping industry.
