General designation foam concentrate for fire extinguishing “Pirena”

Intended for extinguishing of solid combustible materials (class A), and combustible liquids (class B, subclasses A1, A2, B1, B2). DSTU 3789-98. On the characteristics “Pirena” is ecologically pure (has the hygienic passport), biologically soft (biological ability to disintegration more than 90 %).
Has the increased ability of suppression of fire as has been developed specially for suppression of petroleum and products from petroleum. The conformity certificate in system UkrSePrO №UA1.016.0068398-08.
In allukranian competition “The Best Domestic Goods - 2008” general designation foam concentrate for fire extinguishing “Pirena” became the winner in a nomination “Working out and production of fire-fighting engineering and the equipment”.
