Valget af brandslukningssystem bestemmer også, hvilken type skumgenerator der bruges. Skumgeneratorer fås i forskellige i 3 typer: til frembringelse af tungt, mellemtungt og let skum. Forskellen i disse 3 typer findes i ekspansionshastigheden for det skum, der genereres: Jo lettere skummet er, jo højere er ekspansionen.
Tunge skumgeneratorer bruges til tankbeskyttelse, sprinkleranlæg eller fjernslukning med slukningsskærme.
Generatorer af mellemtungt skum bruges til at dække lækkende væske i et indelukket område.
Letskumsgeneratorer bruges til fuldt ud at kunne udfylde lukkede rum såsom lagre og flyhangarer. Når der vælges hvilken type skumslukningssystem der ønskes, skal passende skumkoncentrat også vælges.
Nedenfor finder du mere information om de forskellige typer generatorer.

Kraftig skumgenerator (Fixed/Portable)
The LFG, Low expansion Foam Generator is used for fixed installations. The design allows for rapid coverage of i.e. a bunded area and should be used together with a Class B foam concentrate. Due to the low expansion and the robust design the LFG is suitable for outdoor use also in harsh environment. The generators can be used with most types of foam systems like foam pumps, bladder tanks or In-line proportioners. The LFG produces a uniform heavy foam with a nominal expansion ratio of more than 10:1. -
Plug- and play Letskumgenerator Outside Air
InnoVfoam has developed a “plug-and-play” high expansion foam generator that works on the basis of the “outside air” principle. InnoVfoam's Hi-Ex 600 generator is part of the company's VdS-approved high expansion foam system and it reduces costs of installation, pipework, structural alterations and maintenance. -
Medium skumgenerator
The Medium Expansion Foam Generator is a generator intended for fixed installations. Generally used for coverage of bunded and diked areas, incinerator plants, loading facilities, jetties, spill fires, control of vapor relese from toxic or flamable liquid spill or protection of loading facillities where medium expantion foam is needed. The generators are used with most types of foam systems like foam pumps, bladder tanks or In-line proportioners. The generator normally operates between 3 to 5 bar inlet pressure. -
Skumkop med skumgenerator
The InnoVfoam Tank Foam Generator (ITFG) with an integrated foam chamber and (separate) Foam Pourer (FP) is developed for extinguishing storage tank fires. In order to generate low expansion foam and spread it over the flammable liquid surface the device is provided with an integrated air foam generator. For ease of installation the flanged outlet usually is connected to a flanged nozzle which is welded into the tank-shell close to the tank top. -
Trykskumrør
The High Backpressure Foam Generator (HBG) is a generator intended for fixed installation. Generally used for subsurface and semisubsurface foam application in storage tanks containing flammable liquids. The generators are used with most types of foam systems like foam pumps, bladder tanks or in-line proportioners. The HBG is designed to introduce air into a water/foam-concentrate mix and is always made according to customer needs.
