INERT-SIEX™ 01 suits the most demanding requirements with the utmost respect for the environment using ARGON as the extinguishing agent. The variety of inert agents in our INERT SIEX range provides a greater variety of discharge characteristics for the most efficient protection.


Thanks to its high density, IG-01 extinguishing agent  quickly concentrates in the lower part of the room. It is highly recommended for class A, B and C hazards, in rooms with raised floors. The system works by totally flooding the room, ensuring a complete discharge in less than one minute.


The SIEX team, in compliance with the current regulations for the use of these systems, will study the most suitable design for each hazard depending on the specific needs. With the aid of the latest calculation technology (we have specific VdS certified software) together with our professional experience, SIEX guarantees customized protection regardless of the characteristics of the enclosure.


SIEX has two variants depending on the storage pressure: INERT-SIEX™ 01 at 200 bar and INERT-SIEX™ at 300 bar, therefore the quantity of extinguishing agent can be adapted to the available storage space 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 01 extinguishing agent

Argon is an inert gas which is extracted from the atmosphere. As is completely natural, it is valued as an environmentally friendly extinguishing agent. It is colorless, odorless, tasteless and chemically neutral, making it suitable for occupied areas.

As no blending is required for this extinguishing gas, refills are much simpler and can be carried out anywhere in the world.

This gas extinguishes the fire by reducing the oxygen concentration, however at concentrations which are suitable for occupied areas. It is thus possible to protect hazards when there may be people in the enclosure at the time of the fire, ensuring their safe evacuation,in terms of:  the level of oxygen in the room, the visibility required for the evacuation of personnel, and the absence of chemicals in the discharge.

It is harmless to humans since it is not toxic and does not generate decomposition products (which are harmful to people and equipment). It is a clean agent since it does not leave any residue after discharge. In addition, it is electrically non-conductive and non-corrosive, thus protecting electronic equipment without damaging them.

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).
