BASIC PRINCIPLES



WHAT IS ONE SEVEN®?

One Seven® is a highly efficient extinguishing media, based on Compressed Air Foam principle, which can be used for the effective, safe and fast extinguishing of all kind of fires (Class A, B, D and F) and a large number of industrial applications. It is a very interesting alternative to water spray systems such as sprinkler or water mist with very low application rate. Indeed, according to the NFPA 11, the minimum application rate for CAFS is 1,63l/min/m².

One Seven® extensively fights the fire. One Seven® is the only extinguishing agent which effectively fights all of the fire factors simultaneously.

HOW DOES THE SYSTEM WORK?

A One Seven®extinguishing system consists of several main components, as there are the VDS-Approved One Seven® extinguishing system control, the One Seven® foaming module, a water and gas supply, the piping towards the discharge devices specially developed for certain fields of applications.

The compressed gas foam is being generated in the foaming module where water with a minimum inlet pressure of 8 bars will be mixed with specially developed One Seven® foam concentrate under defined and controlled proportioning rates relying on controlled volume streams. In a special and patented mixing apparatus “Compact Foam Generator” the water-foam-concentrate solution is foamed with air and other gases also with precisely controlled pressure, and flows. Out comes a very homogeneous and highly efficient extinguishing agent: One Seven® compressed gas foam. This agent is perfectly reproducible in all situations.
