INTRODUCTION

The CSC CAFS fire truck is equipped with DC-CAFS60/45M compressed air foam fire extinguishing system with strong water mist fire extinguishing function. CAFS is a kind of high-energy storage foam, which contains a lot of high-pressure air. In CAFS, water is still the most important part. It is mainly composed of foam, compressed air and water pre-mixing to fully refine and foam the foam aqueous solution. This greatly enhances the ability to penetrate the combustion object and adhere to the surface of the combustion object. It has the characteristics of low water consumption, high power, strong foam fire extinguishing penetrability, minimal re-ignition, high fire extinguishing efficiency, long foam range, large occupants, strong comprehensive performance, and centralized and easy control. It especially saves water and foam liquid, is efficient and environmentally friendly, and will not cause secondary damage. The system is simple to operate, maintenance-free, CAFS can be output with one button, and there is no need to clean the foam pump after use. CSC compressed air foam fire trucks are widely used in underground, petroleum, chemical, large shopping malls, high-rise residential buildings, key cultural relics, station terminals, etc.

FEATURES

●  High fire extinguishing efficiency: The fire extinguishing dose produced by one ton of water in the CAFS system is equivalent to the amount of seven tons of water; therefore, the extinguishing effect of the fire extinguishing agent produced by one ton of water is much greater than that of seven tons of water.

●  Fire safety:

1: The foam produced has low fluidity, strong adhesion, and has a good isolation and protection effect on unburned materials in the fire field;

2: Continuous cooling on the surface of burning objects reduces the risk of re-ignition;

3: The cooling speed is fast, the heat insulation is strong, and the heat radiation protection is provided to the combatants;

4: It has strong fire control ability, fast extinguishing speed, reduces the formation of smoke, and reduces the risk of flashover (smoke burning);

5: Because it is not easy to flow and has little moisture, it will not cause great wetting and damage to unburned materials (such as clothing, electrical appliances, warehouse products, etc.).

●  Convenient operation and use:

1: The operation is automatic, simple and convenient, and can be put into battle at any time;

2: The hose is light (85% of the hose is air), easy to drag;

3: It can be transported for long distances up to 2000 meters, which has obvious advantages for firefighting in mountains and tunnels;

4: The pressure loss of the hose is small, and the conveying height is more than 100 meters. It can still extinguish normally. It is very convenient for high-rise buildings to extinguish.

●   Conducive to environmental protection:

1: Traditional foaming agents have toxic and side effects and are not easy to decompose. They have a long-lasting impact on the environment. The "One Seven System"(One- Seven-bubble theory: A small drop of water turns into many bubbles, and the surface area of the water is expanded seven times, which greatly increases the adhesion and penetration of the burning material, and improves the coverage and cooling effect. The seven bubble theory is also known as the design basis of CAFS. ) fire extinguishing agent itself has almost no pollution to the environment, no pollution to humans, animals and plants, and is naturally biologically decomposed. Strong force, generally more than 99% will be decomposed and dissolved within 15-20 days.

2: Because of its low fluidity, there is almost no water damage, so it has little pollution and damage to the surrounding environment of the fire extinguishing site.

●  Low fire-fighting water, effectively reducing water damage: CAFS directly extinguishes Class A fires with only less than 1/3 of the traditional water consumption, and the water used by dry foam for cooling protection is only 1/10 to 1/20 of the traditional water consumption. The application of the CSC CAFS fire truck enables the firefighting force to achieve continuous fire-fighting capabilities with vehicle-mounted fire monitors under the existing urban fire hydrant water supply conditions. It also can simultaneously use 8-10 fire water guns for extinguishing and cooling in a fire area. The combat capability of protection.

●  The amount of water and foam is small, and the cost of use is low: Because the water is all attached to the surface of the foam, it all plays the role of heat absorption, reduces the loss of water, and overcomes the weakness of conventional water tank fire trucks with large water consumption. Under fire extinguishing conditions, it can save more than 80% of water compared with traditional water tank fire trucks, so it is especially suitable for use in urban and rural areas with drought and water shortage. Compressed air foam is a high-expansion foam with a high foaming rate, usually the formula ratio is only 0.2% to 0.5%, while the formula ratio of ordinary foam is 3% to 6%, and the amount of compressed air foam concentrate is only 1/10 of that of ordinary foam.

●  Strong maneuverability and safer vertical fixation: When using water and other foams to extinguish fires, the water belt is heavy, the foam monitor has a large recoil force, and the combatant's physical strength is high. It is not flexible to transfer the water gun position, and it is inconvenient to be at high altitude and small Fight in the environment. When using foam to extinguish fire, the foam-filled hose is light in weight, and it is very convenient to transfer the water gun position. The combatant consumes less physical strength and is convenient for extinguishing fire in high altitude and narrow environment. At the same time, it is safer to fix the hose vertically.
