INERT-SIEX™ 100 uses Nitrogen for a clean, safe and 100% ecological extinguishment. This gas is widely used in a variety of extinguishing systems due to its excellent pressurization conditions.


In this case it complies with equal smothering efficiency by reducing the oxygen concentration to extinguish the fire, while leaving a percentage of oxygen suitable for occupied areas. Due to this feature, hazards can be protected where there is the possibility that people will be in the enclosure at the time of the fire, ensuring their safe evacuation both in terms of the level of oxygen in the room, and the absence of chemicals in the discharge. In addition, its physical and dispersion properties help maintain visibility during the evacuation.


It is highly recommended for class A, B and C hazards. The system operates by total flooding of the room, ensuring discharge in less than 1 minute with the safety conditions mentioned above. SIEX has two variants depending on the storage pressure: INERT-SIEX™ 100 at 200 bar and INERT-SIEX™ 100 at 300 bar; this makes it possible to adapt the quantity of extinguishing agent required, to the storage space available for the cylinders.


The system is optimized for the worst case conditions, all components are certified to ensure the strictest performance. These are necessary for the storage, detection, release and discharge of the agent at the right moment.

About IG 100 extinguishing agent

Nitrogen gas is clean, generates no combustion products, is non-toxic, and does not cause irritation to the skin and eyes. It is harmless to people at design concentrations and is therefore ideal for extinguishing fires in occupied spaces. In addition, when discharge occurs, visibility is high, so that evacuation is not impaired.


Pure nitrogen is obtained by distillation of air, so it is a completely environmentally friendly gas with zero ozone depletion (ODP) and zero global warming potential (GWP). Since it is not a mixture of gases, it is easy to refill and can be acquired at any geographic location.

Nitrogen is non-corrosive and can be used at normal temperatures with materials typically used in industry and construction. It is electrically non-conductive and is therefore highly recommended for protecting electrical and electronic materials. Colorless, odorless, tasteless, electrically non-conductive and chemically neutral gas

Silencers for Data Centres

Data centres include increasingly sensitive devices, especially to noise. High frequencies combined with sound pressures of over 110dB may affect the operation of their hard drives and cause permanent damage. It is essential that the fire protection system avoids damage not caused by the fire, but generated collaterally by the noise of the discharge.

SIEX SALC silencers reduce noise to below 90 dB in the most adverse case, far below the 120 dB of a free discharge and the 100 dB available on the market. It also allows for installation both in new projects and existing. They offer maximum benefits in use with inert gases (60 second discharges) and are compatible both with falling pressure technology (with restrictor) and with the new Constant Flow Technology (flow rate control in the DR valve).
