Extremely hazardous fires require top-level skills and innovative agents. Twin-Agent Fire Suppression Systems provide proven technology to fight large flammable liquid and gas fires. Twin-agent technology incorporates the fast flame knockdown of a dry chemical with the fire securing capabilities of film-forming foam. The twin-agent attack provides the most effective extinguishing and securing capability known for many flammable liquid fires. It is most commonly used in industrial areas such as petrochemical, petroleum, natural gas and aviation. These systems can be mounted on vehicles, skid mounts or permanent stations. Application is from twin hose lines connected together at the nozzle, one flows the dry chemical agent and the other foam.
