Fire extinguisher self-generating powder OSB was developed in 1991 in conjunction with the All-Russian Institute of Fire Protection of the Ministry of Emergency Situations of Russia.
The fire extinguisher combines the properties of a heat detector, a source of pressure for feeding a fire extinguishing agent into the combustion zone and a container for storing it.
The OSB is a sealed glass vessel filled with a fire extinguishing powder and a special substance – a gasifier.
It is installed over the place of possible ignition and automatically operates when the temperature rises in the installation zone up to 1000С (OSB-1) or 2000С (OSB-2).
The pulsed discharge of the extinguishing powder into the protected volume results in a highly effective local volume suppression of ignition. Thus, the fire extinguisher works directly from the thermal manifestations of the fire, does not require the means of automatic control and human intervention in the extinguishing process.
Currently self-extinguishing fire extinguisher OSB is widely used at various facilities. They are accepted for the supply of ships and coastal facilities of the Navy, they protect the rolling stock of the Ministry of Railways and the Moscow Metro, many large industrial enterprises in Russia and CIS countries.
Experience in the use of SWA indicates that they are sufficient to protect small warehouse, technological, household, utility rooms, garages, etc. They can also be used to extinguish fires in cable boxes and tunnels, transformer and switchboard rooms, and in separate electrical panels under voltage.
The effectiveness of self-extinguishing fire extinguishers in real conditions is confirmed in numerous reviews that came to the company from the leaders of various enterprises.
