High Expansion Foam
The Marine
high-expansion foam systems supplied by Tyco Marine Services automatically seek
out and suppress fire at the source using much less water than a stand-alone
water sprinkler system. With expansion ratio’s are typically greater than
500:1, high-expansion foam is suitable for numerous applications including three-dimensional
hazards, confined spaces and vapour suppression.
The system
is designed to fill the protected space at a rate of at least 1metre in depth
per minute, with sufficient foam to produce a volume five times that of the
largest space protected.
The
generators comprise a steel enclosure with a pipe and nozzle array in the inlet
and a perforated screen in the outlet. The generators are arranged so that they
draw fresh air into their inlet, which may be ducted. They must also be located
in elevated positions so that they are not affected by fire. To overcome this
potential problem the foam discharge may have to be ducted to the required
locations.
These
systems use a water powered generator fan. When the foam water solution is
discharged through the unit, the powerful air stream created by the generator
fan immediately expands the foam, which rapidly engulfs the protected
area. The expanded foam quickly creates a blanket across the burning fuel
depriving the fire of oxygen that in turn extinguishes the fire.
