Introduction
Mining, Off-Road, Forestry and Construction equipment operating in harsh outdoor environments can be subjected
at any time to the threat of fire, which may spread rapidly through the equipment endangering life and resulting in
damage to major capital equipment and loss of production. The installation of a fire detection and suppression
system is essential to minimise the risk to both operator and equipment.
PEFS F3 is a pre-engineered aspirating foam spray suppression system designed specifically to cope with the
harsh operating conditions experienced by mobile and transportable equipment. PEFS F3 systems consist of
pressurised cylinders containing fluorine free foam solution, actuation devices to initiate discharge and a discharge
network containing aspirating spray nozzles to direct the foam spray on the hazard. PEFS F3 systems may be
configured for both manual and automatic operation.
PEFS F3 systems offer impressive fire suppression capabilities using
fluorine free
foam through specially
designed naturally aspirating spray nozzles that generate an improved foam application over standard foam spray
systems. Strategically positioned nozzles direct the
aspirated foam spray and provide “three-dimensional”
firefighting properties, allowing the system to suppress pressure fires such as might occur from a ruptured fuel or
hydraulic line. The air aspirated droplets of foam are extremely efficient at absorbing large amounts of heat and
turn to steam which further enhances the three-dimensional firefighting properties of the PEFS F3 system.
