Inert Gas – Nargotech®
Our Inert Gas: A Half Argon & A Half Nitrogen
Nargotech®: Natural Gases For The Environment’s Sake
An efficient Nargotech® fire protection system requires an adequate study and preliminary risk analysis aimed to define: the kind of combustible involved, its related concentration of the project and the quantity of mixture to use. The extinguishing concentration is the minimum concentration needed to suppress fires, calculated on the basis of fire test; this is crucial to define the project concentration.
Products
Nargotech® is a clean agent fire fighting system which uses a mixture of Inert gases composed of 50% Argon and 50% Nitrogen. This mix is pressurized at 200 or 300 bar and it is characterized by the same density of air.
Nargotech® is a odourless and colourless gas with no environmental impact. It is not corrosive, nor electrically conductive. Furthermore, thanks to the innovative silent nozzle, the Nargotech® system reduces the risk of loud noise during the gas discharging.
Nargotech® can be used to efficiently suppress any class fire.
Operation
The Nargotech® system operates by total flooding: it respects the environment and guarantees a prompt suppression of the fire by lowering the percentage of oxygen in the atmosphere. When the concentration of oxygen in the air lowers under the 15%, in fact, the combustion of more than 90% of the combustibles is inhibited. Therefore, the discharging of Nargotech® in the areas affected by the fire, guarantees an immediate suppression of it.
The system can be actuated by: Automatic actuation thanks to the detection system located in the protected area. When it detects the fire, the control station activates the solenoid valve located on the pilot cylinder, and consequently, the entire cylinder skid through the pneumatic line.
Electrical/manual actuation. Its operation is identical to the automatic system once and the activation is set by a manual command switch located outside the protected area.
Manual emergency actuation. In case of lack of power energy, the system can be activated by emergency command control.
