Twin-Agent Units

Chemguard engineered and manufactured Twin Agent Systems combine the most advanced concepts of dry chemical and AFFF agents.  These self-contained systems utilize nitrogen to charge and expel a combination of dry chemical in one vessel (to extinguish the fire) and the premix foam solution in the other (to blanket the flame-free surface) through the twin hose assembly.  Very effective against 3-dimensional and pressurized fuel fires and spills as well as the securing, cooling and sealing ability of AFFF.  Most systems are designed with either one or two hose reels for manual fire fighting and can be fabricated with a twin agent monitor for use in extinguishing larger hazard fires.  Our systems can be easily activated automatically or individually with a simple lever or single hand wheel, to control the flow with a handline nozzle. Depending on unit size, handline flow rates vary from 5 to 8 lbs. per second for the dry chemical and 30 to 60 gpm for the premix AFFF solution. All components are mounted on a full skid assembly or can be trailer mounted for mobile use.
