ICAF

INTEGRATED COMPRESSED AIR FOAM SYSTEM

Compressed air foam (CAF) is generated by the combination of compressed air, water and foam concentrate in the right proportions, to create a homogeneous foam solution similar to shaving cream. CAF is delivered with high momentum through a fixed piping system, and distributed over the hazard via an approved discharge device. The ICAF compressed air foam system is FM Approved as a local application extinguishing system for class B pool fires, spill fires and cascading fires. Full-scale fire tests have demonstrated ICAF to be an extremely effective extinguishing mechanism for flammable and combustible liquids, both miscible and non-miscible.

The unique physical properties and texture of CAF allow it to form a stable and uniform foam blanket overtop the liquid surface. The robust foam blanket developed during a discharge works at the fuel surface, creating an effective vapour seal to establish a physical separation between the fuel and the burning vapours. Because CAF is generated through aeration in a mixing chamber versus agitation at the nozzle, it has higher expansion ratios and longer drain times than conventional low-expansion foam systems. This translates directly into enhanced extinguishing and burnback performance.

REDUCED INFRASTRUCTURE REQUIREMENTS FOR FIRE PROTECTION

WATER SUPPLY
ICAF 
can eliminate or reduce the size of water supply tanks & fire pumps

DRAINAGE & CONTAINMENT
ICAF 
can eliminate or reduce the size of drainage and containment systems including spill tanks and oil separators

DISPOSAL COSTS
The significant reduction in foam and water required for ICAF reduces
the costs associated to clean-up and disposal of foam during discharge testing or after a fire.
