Until recently, the primary focus of fire protection designers was on creating a reliable system to detect a fire as quickly as possible automatically and to extinguish it effectively. Now however, a new method, based on the reduction of oxygen in the protected atmosphere, has redefined the possibilities available to us in fire protection design.
We are now able to create fully protected environments and to completely eliminate the fire hazard by changing the atmosphere within a building whilst allowing access to people at the same time.
The N2 FIREFIGHTER® methodology prevents the development or spreading of open fires by deliberately and precisely adjusting the ration of nitrogen to oxygen in the protected atmosphere.
As a first step, the so-called “pull down” step, i.e., establishing a self-extinguishing atmosphere in the premises to be protected, such machinery is activated in order to reach the safety threshold value as fast as possible; subsequently, part of the machinery is deactivated and kept in a stand-by state. The environment is constantly monitored through an analyzer and dedicated software.
Upon detection of an increase in the oxygen rate deviating from the target value, the electronic analyzer, according to rotation logic, activates a few machines for as long a time as needed to decrease the detected oxygen rate.
Advantages of ORS:
Protected premises are safe 24/7/365
The fire hazard is completely eliminated
No consequential damages due to a false alarm
No consequential damages caused by historical extinguishing agents
Prevention method is environmentally safe, non-toxic, non-polluting, non-residual
Ease of installation and cost effective compared to standard extinguishing methods
Due to Oxygen Reduction System N2 Firefighter technology no negative aesthetic impact to the building
Easy protection even in areas difficult to reach or subject to strong regulation restrains
Can easily be integrated with main fire panel or building management systems
ORS N2 FIREFIGHTER® is maintenance friendly
No additional space required for banks of high pressure cylinders
Protective atmosphere slows down the degrading process of certain materials
N2 FIREFIGHTER® protects objects of all sizes, from miniature to giant dimensions
