The (trolley) Wheeled Fire Extinguisher with double extinguishing, also called as Twin agents, are constituted from an only trolley on the strong rubber wheels mounted spheres, and from two tanks charged with powder ABC/SBC (on request) / PBC (on request) and with foam A.F.F.F concentrate. The combined action renders them unsurpassable in the fight against the fire. On great fires of inflammable liquids the foam action creates a sealing effect that pulls down flames, and in case the extinction has not been obtained, the powder easily extinguishes the residual flames.
