Clean agent: eco-friendly gases

The new generation of eco-friendly chemical gases

For fires at high risk of immediate propagation or located in confined spaces, Clean agent systems are an extremely efficient solution.

Clean agents are eco-friendly gases able to suppress immediately fires. These fire fighting solutions are engineered to mix in a homogeneous way the gas with the air present in the protected room, in order to reach the concentration needed to extinguish the fire in 10 seconds. Our systems use the most common clean agents, the hydrofluorocarbons (HFC), as Novec1230™, HFC227ea, HFC125.

The HFC solutions stock the gas in the liquid state and require less quantities of extinguishing agent then other gas systems. For this reason, the clean agent solution need smaller spaces.

In the last decade, fire fighting gas technology has been evolving due to the gradual substitution of Halon1301, which has lead to the engineering of brand new eco-friendly fire fighting products. HFC solutions operate by total flooding, thanks to the mix of air and gas that acts directly on the combustion process, inhibiting it.

This kind of intervention has the advantage of creating homogeneous conditions in the whole protected area, without damaging other equipment exposed to the fire. The air-gas concentration must be maintained constant until the flames are totally suppressed.

The retention time and the gas escapes are verified through “Door Fan Integrity Test”.
