Inert gases are “clean” extinguishing agents with zero effect on the protected goods and on the environment, on global warming in particular.

The gases used are completely inert, colourless, odourless and non-corrosive, hence they are ideal extinguishing agents for use in areas occupied by people. Each gas family acts on the fire with different extinguishing mechanisms (cooling, choking, chemical action, etc.) and has a specific field of application.

The inert gases that Castagna Antincendi supply with their systems are natural products already present in the atmosphere; Nitrogen IG100, Argon IG01, IG55 (argon + nitrogen) and IG541 (argon + nitrogen + Co2)

Tutti gli impianti a gas inerte All CASTAGNA ANTINCENDI inert gas systems are available in versions KIT, pre-engineered or installed on a turnkey basis. We store the gases as compressed gases in 2 to 140 litre cylinders under high pressure (150, 200 or 300 bar).

The inert gas fire extinguishing system is composed of cylinder groups, collector, pipe network to transport the gas, brackets/clips and suitable dispensers calibrated following approved hydraulic calculation; this allows propagation of the gas in the environment with the necessary design concentration.

Castagna Antincendi inert gas firefighting systems can also be enhanced with several accessories.

Automatic activation of an inert gas system occurs through different types of smoke detection systems, by means of a manual discharge activation button or manually operating the lever of the pilot cylinder.

To build an inert gas system it is necessary to have our specialised technicians verify the characteristics of the volumes to protect beforehand by means of certified “Door Fan Test”. The test will allow us to determine whether or not it is necessary to install pressure relief dampers equipped with pre-calibrated springs.

Castagna Antincendi propose the innovative CDT (Constant Discharge Technology) valve in cases where it is necessary to use an inert gas system that has the characteristic of discharging the product in a constant and controlled manner. With the constant discharge of the gas it is possible to drastically reduce the total area (and therefore the number) of the pressure relief dampers.

The gradualness of the discharge often makes it possible to also reduce the diametres of the pipes to lay.
