The ArmanFire 3TB-227 system is designed for extinguishing fires in electrical panels. It is a direct action system, the detection tube when burned proceeds to the release of the extinguishing agent directly by the place where the flame has been generated. They can be installed easily in any electrical panel on the market, occupying a minimum space inside the box. They function as totally autonomous systems, with total and instantaneous detection at any point of the electrical panel, thanks to the 20 meters of detector tube. The systems produce an effective extinguishing with a double effect of cooling and containment of the fire.
