DSPA offers complete detection and extinguishing systems, applicable to any fire hazard. DSPA Aerosol was originally developed as an alternative to Halon. Unlike Halon, DSPA is environmentally friendly. The active substances of the DSPA Aerosol are solid micro particles that fill the area completely and attack the combustion process at a chemical level. As a result, the flames are instantly knocked down and the energy removed from the fire.
