Model VRC Foam Ratio Controller

UL Listed high expansion foam systems protect applications requiring fast and optimal fire suppression, such as aircraft hangars, with fluorine free concentrate consisting of hydrocarbon surfactants blended with various solvents, preservatives and stabilizers. High expansion fluorine free systems require various system components — such as the Model VRC Ratio Controller — for effectiveness and quality in flammable liquid protection. Ratio controllers accurately proportions foam concentrate into a water stream over a wide range of water flow rates, and are an integral part of an approved foam system. In addition to the ratio controller, the main components of the approved foam system are specific foam concentrates, a foam storage tank, a concentrate control valve and foam discharge devices.  Designers and estimators can use the innovative HiEx Foam Estimator tool to assist with calculating the number of generators and amount of concentrate needed for NFPA 409 and UFC projects!
