General designation foam concentrate for fire extinguishing “Sn³zhok-1”
Enterprise “Pirena” is in the market of fire-fighting services of Ukraine since 2000. In this time our enterprise became widely known as the manufacturer of general designation foam concentrate for fire extinguishing “Sn³zhok-1”.
Annually more than 2 thousand tons of foam concentrate were delivered on objects of an economic complex.
Every year technologies are improved, new production is manufactured. Together with scientists of Scientific Research Institute of Fire safety of the Ministry of Emergency Measures of Ukraine, enterprise “Pirena” led working out of a compounding new foam concentrate which on the technical characteristics would exceed indicators of “Sn³zhok”.
We are glad to inform that work has been successfully conducted and in May our enterprise has received the certificate
on new foam concentrate a general purpose “Pirena”. ¹UA1.016.0068398-08. 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
Since May, 2008 general designation foam concentrate for fire extinguishing “Sn³zhok-1” is laid off!
Scientists of Fire Safety Institute conducted comparative researches of samples foam concentrate by “Sn³zhok-1” and “Pirena” that is confirmed by the corresponding protocol.
Researchers have confirmed higher ability of foam to extinguish fire, and in a consequence of it, more economic cost of foam.
The comparative characteristic foam concentrates “Sn³zhok-1” and “Pirena”.
