CONCENTRATE CONTROL SUPPLY SYSTEM - F500 EA vs WATER

Concentrate Control Supply (CCS) systems are available to proportion F-500 EA, Pinnacle foams and Dust Wash.

For most firefighting systems, HCT recommends F-500 Encapsulator Agent.

F-500 EA extinguishes a fire by cooling the fuel and surrounding structures, encapsulating the fuel and interrupting
the free radical chain reaction.

Removing any one of these elements could extinguish a fire, but F-500 EA eliminates all three.

Because of these unique capabilities, F-500 EA is excellent fighting three-dimensional fires, Class A, Class B polar
and nonpolar, Class D and even some specific Class C fires.

Most of the fire suppression systems HCT protects are three-dimensional, such as warehouses, turbines, transformers
or truck loading racks.

In addition, many of these applications involve nonpolar Class B fuels, such as oil, diesel fuel or gasoline and polar
Class B fuels, such as ethanol and ethanol-blended fuels.

F-500 EA also reduces the surface tension of water making the water droplets better able to spread out over a larger
surface area and better penetrate Class A fuels.

Examples are coal handling, recycled rubber crumb and other combustibles.

To better understand the capabilities of an F-500 EA enhanced fire suppression system vs. a water system, we refer to
independent testing conducted on behalf of a large power company.

The purpose of the testing was to prove to FM Global that their new recommendation of .40 gpm/ft2 application coverage
for turbine protection was unnecessary if F-500 EA was supplemented into their existing .25 gpm/ft2 suppression system.

Upgrading the system would have meant considerable capital investment.

The testing involved plain water and water with 3% F-500 EA at four discharge densities and two burn scenarios using
diesel fuel.

The test showed the amazing cooling capabilities of F-500 EA.

The temperature rapidly dropped from 1200F to 115F in less than 20 seconds, whereas the water lowered the temperature
to about 280F, but it then climbed and continued to average 400-500F until minutes later when they stopped the test.

Just adding 3% F-500 EA to the water makes the solution so efficient at fighting the fire that 83% less water was used.

After the testing was completed, they concluded that not only was there no need to redesign their existing fire
suppression system, but they could exceed the performance of a .40 gpm/ft2 system by simply adding F-500 EA to their existing system.

F-500 EA can do it all!
