The type of foam maker depends on the selected foam extinguishing system. Foam makers come in three varieties for generating low, medium and high expansion foam. The three types differ in the amount by which the foam that the system produces expands: the lighter the foam, the higher the expansion.
Low expansion foam makers are used, for example, for tank protection, in sprinkler systems or remotely operated fire monitors.
Medium expansion foam makers are used, for example, for covering a liquid spill in an enclosed area.
High expansion foam makers are used, for example, for completely filling an enclosed space such as a warehouse or aircraft hangar. The type of foam maker used depends entirely on the choice of a specific type of foam extinguishing system.

Plug- and play high expansion foam generator
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. -
Low expansion Foam Generator (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. -
Low expansion Foam Nozzle
The Low expansion Foam Nozzle is designed for use in a deluge type foam sprinkler system and in- tended for use with all types of foam solutions from a separate foam proportioning system. The sprinkler has a compact and rigid construction and can be used both inside and outside; it can be mounted horizontally or vertically. -
Medium Expansion Foam Generator
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. -
Tank Foam Generator
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.
