Fire extinguishing module -2.5-2С (Buran-2,5-2С))

Powder fire extinguishing unit “Buran-2,5-2С” (called later as the unit ) serves for localization and extinguishing class of А, В, С fire and alive electrical equipment with any voltage.

The unit is the main elements for the construction of automatic powder fire-extinguishing system used in industrial, storage and other rooms.

The unit has the function of self-starting.

The unit is not used for extinguishing of alkali and alkaline-earth metals as well as the substances that can burn without air.

The unit is a stationary fire extinguisher and does not contain ozone destructing substances.
