The powder fire extinguishing module “Buran-2,5vsr” in explosion-proof design is intended for localization and extinguishing of fires of class A, B, C, as well as fires occurring in live electrical equipment, without limiting the voltage, according to the requirements of clause 9.1.6 JV 5.13130.2009.
The module is used as an actuator in automatic fire extinguishing installations and belongs to the class of stationary fire extinguishing means.
The module, unlike the “Buran-2,5-2S”, does not have a self-launch function.
The module does not contain ozone-depleting substances.
The module is not designed to extinguish the burning of substances, the combustion of which can occur without access to air (aluminum, magnesium and their alloys, sodium, potassium, etc.).
The climatic performance of the module UHL3.1 in accordance with GOST 15150 for the ambient temperature from minus 50ºC to plus 50ºC with relative humidity up to 98%. Marking of explosion protection 2ExemIIBT3 X in accordance with GOST R 51330.0.
Modules can be used in rooms and outdoor installations in hazardous areas of Class 2 according to GOST R 51330.9, in which explosive mixtures of categories llA and llB can be formed according to GOST R 51330.11 with an autoignition temperature of more than 200ºC (groups of explosive mixtures T1, T2, T3 according to GOST R 51330.5 ).
Rules for the use of modules in hazardous areas – in accordance with the requirements of GOST R 51330.13, GOST R 52350.14, Ch. 7.3 PUE, PB 08-624-03.
The modules “Buran-2,5vsr” are used for the protection of gas and oil refining facilities, gas stations and AGDS, lacquer and paint stores, paint preparation departments and spray booths, pumping rooms for oil products, various shops and premises with explosive production, etc.
Description
In the protection of premises belonging to the explosion-hazardous category (categories A and B for NPB 105-95 and explosive areas for PUE), the equipment that is part of the installation when it is located in the protected area must have an explosion-proof design.
The “Buran-2,5vsr” modules with the level and type of protection 2ExemIIBT3 X are used for the protection of explosive areas in which substances and materials of category IIB and group T3 are treated according to PUE (Table 7.3.3.).
Thus, modules “Buran-2,5vsr” with this type and level of explosion protection are used in fire-extinguishing systems for the protection of buildings, premises and facilities in which: acetone, propane, butane, all types of gasoline, kerosene, various solvents, P.
More detailed information on the categories and groups of substances and materials and, accordingly, the applicability of the Buran modules can be determined from Table. 7.3.3. Electrical installation rules chapter 7.3. «Installations in hazardous areas».
