The Buran-8vsr module in the explosion-proof version of RV has the marking РВ ЕхsiаIХ / 1ЕхsiаIIС110 ºС Х except C2H2, in accordance with GOST R 51330.0 and belongs to the group of mine explosion-proof electrical equipment.
This is the first powder module in Russia, which can be used in any explosive facilities with almost no restrictions, including – in mines and mines, dangerous for gas (methane) and coal dust.
Restrictions on the use for this module are acetylene (as indicated in the marking) and carbon disulfide, since carbon disulfide belongs to group T6 in the category of mixture IIC.
Two models of Buran-8vsr are available in the RV version:
Buran-8Uvzr in the RV universal version, ceiling mount for rooms with a ceiling height of 2.5 to 6 m.
“Buran-8Nvzr” in the design of the RV wall mount, providing a powder cloud in the horizontal direction for a distance of up to 8 m. For this module, the height of the ceiling of the room is no longer taken into account.
Powder fire extinguishing modules “Buran” were previously widely used in the mining industry in fire extinguishing systems of various fire hazardous areas – conveyors, etc. The appearance of the new “Buran” significantly expands the scope of powder fire extinguishing and allows successfully solving the issues of fire protection of explosive objects for various purposes.
