The U.S. Fire Administration conducted a series of studies and test fires and found that a CAF hose line is significantly lighter and easier to handle than a conventional water line. This is because the foam in the hose is mostly air.  MORE CAF FACTS


The ACAF® Rimseal System is fully automatic and designed to extinguish floating roof tank rimseal fires in their infancy. A self-contained CAF generator, combined with special rimseal nozzles and thermal linear heat detection, provide a system to protect the entire rimseal space of a floating roof tank. When activated the system will automatically discharge CAF into the rimseal void filling the space with CAF in seconds. Total flooding of the rimseal space with CAF provides a seal of foam that quickly extinguishes a fire and protects against reflash. The ability of a CAF generator to create and deliver expanded foam rapidly gives this system the speed that is needed in this application.  Ideally suited for Oil Storage and Floating Roof Tanks.


Our systems are available in either a self-contained or fixed water supply configuration.

Self Contained Supply, Automatic, Fixed Pipe System (SC)

The SC configuration is recommended for areas where water is not readily available. This automatic, pre-engineered, stored energy-type, fire suppression system uses CAF as the fire suppression agent. Unique to the industry, it does not require a water supply to create CAF.

Fixed Water Supply, Automatic, Fixed Pipe System (FW)

When a reliable water supply is available a CAF solution may be designed using ACAF’s® fixed water supply system. This system requires a foam proportioner to mix foam concentrate and water to a pre-determined ratio of 3% or 6 %.
