Pre-Mixed Foam Units are suited for offshore installations, oil tankers, aircraft hangars, fuel storage tanks, helidecks, pumping stations, and land wellsite production and fracking areas in providing rapid response flame attack on Class B fires consisting of flammable liquid spills and hazards.
The foam acts as a blanket source to smother and cool pooling hydrocarbon liquid while additionally acting as a vapor suppressant to aid in preventing re-ignition of the hazard area. These systems address limitations experienced with traditional foam proportioners, around-the-pump systems, foam monitors, applicators, and foam concentrate storage tanks.
Variables with these other types of systems include inlet pressure, back pressure restrictions, nozzle restrictions, variable flow rates, and mobility, issues not present in pre-engineered complete systems.
