Bele L-100 high expansion foam generator
The Bele high-expansion foam generator is designed for total flooding systems or local application of high expansion foam. The massive volume of expanded foam will keep the water application to a minimum and extinguish through a combination of vapour surpression, cooling, oxygen reduction and wetting capability. Depending on foam concentrate used, it is also suitable for inside/hot air applications and polar solvents. As standard, the Bele S-250/400 series have stainless steel 304 body, carbon steel red epoxy painted (RAL 3000) connection piping and brass nozzles.
- For inside/hot air use
- Excellent foaming properties
- Recommended foam Fomtec LS range
- DIN or ANSI flange option
Recommended foam concentrate
- Fomtec LS EXP
- Fomtec LS xMax
- Fomtec LS aMax
Bele units can be installed for horizontal or vertical hi-ex foam application. The foam generator is attached to foam premix pipe system with threaded connection as standard. The foam premix feeding line should be equipped with a strainer mesh size no greater than 2,5 mm.
The Bele high expansion foam generators can be used for
applications such as:
- Aircraft hangars
- Ship holds and engine rooms
- Power stations and transformers
- Gas turbine generators
- Flammable liquid storage
- LNG vapour surpression
(1): The expansion ratio is depending on foam concentrate type. Results achieved in full scale tests. Please consult Fomtec for most suitable hi-ex foam concentrate for your application.
Flow rate L/min – 4 bar
Expansion ratio 4 bar (1)

The Bele high expansion foam generators are water driven, passive type, and do not require any other power source to function in case of fire. It can be attached to any foam proportioning system such as inductor, bladdertank or foam pump.
For correct operation make sure that:
- Air at the suction side is clean (depending on foam
- The foam generator mesh must be clean and free of
grease and other foreign material.
- Grooved inlet connection
- DIN or ANSI flanged inlet connection
- Clean the strainer in foam premix line.
- Clean the generator externally and internally with
