Hi Ex-Foam Generators (FCHX-2)
FIRECHEM Hi Ex Foam Generators are used for total foam flooding in enclosed areas and also act as a powerful smoke extractor.They require no other source of power such electricity or gasoline engines. They are powered by the foam solution driving a hydraulics (water) motor. The expansion of the foam solution is achevied by spraying the solution onto a stainless steel screen, and then an air stream created by the fan attached to the motor forces air through the screen to produce a mass of foam bubbles. The continuous flow of the foam solution and the movement of air through the screen will generate large volumes of foam.Typical hazards where FIRECHEM High Expansion Foam Generators may be used to provide fire protection are:In addition to the above hazard types involving Class A and B fires, high-expansion foam is effective in controlling liquefied natural gas (LNG) fires by blocking heat feedback from the flames to the LNG thereby reducing the vaporization rate.High-expansion foam is also effective in reducing vapor concentrations downwind from un-ignited LNG and other hazardous low-boiling-point gaseous products such as ammonia spills.FIRECHEM High-expansion foam generators are designed in accordance with NFPA 11 Standard for“Low, Medium and High-Expansion Foam System.”PRODUCT DESCRIPTIONAREAS OF APPLICATIONLNG Tank Farms / Loading FacilitiesFlammable Liquid Storage AreasHazardous Waste Storage FacilitiesShipboard Engine Rooms, Bilges and HoldsRoll Paper WarehouseChemical Storage FacilitiesFlammable Liquid Packaging AreasCable TunnelsAircraft HangarsAPPROVALSHIGH EXPANSION FOAM GENERATORFIRECHEM Hi Ex-Foam Generators (FCHX-250) are designed to expand foam solution in to millions of tiny stable bubbles in which the foam solution is expanded in volume to a range of 200:1 to 450:1 approximately depending on the generator selected, solution flow rate, foam concentrate and the operating pressure.
