Have you ever asked what features a high expansion coefficient foam system has? ⭐ How do they work? What type of fire is it used for? fire fighting use area...

1. Features of high expansion coefficient foam system

* Provide fast and effective fire extinguishing solution for narrow space fires such as machinery compartments, warehouses, dry materials.. with a filling rate of 1.8 cubic meters per minute.

* The system can be installed as a total anti-flood solution for the entire machine room or for individual compartments

* Rapid system activation helps to minimize fire and thermal damage to equipment and structures

* The foam is not harmful and the cooling effect prevents the fire from breaking out after the fire is extinguished

* Non-hazardous decomposition can cause damage to the environment

* Expansion ratio up to 1:666 with a standard pressure of 6 bar using internal air

2. Benefits of high expansion coefficient foam system

- A low cost effective solution

- Designed for optimum system performance, keeping both installation and operating costs low

- No external foaming room required. High expansion rate and stable condition of foam results in very fast filling speed with low water consumption and foam concentration.

- 1:666 expansion ratio uses internal air eliminating the need for wide air ducts and fans

- Easy to install and operate

- Requires minimal maintenance

- For service purposes, alternative foam concentrates are commercially available today.

3. Specifications and description of high expansion coefficient foam system

- The system uses a synthetic foam concentrate along with fresh water/sea water and internal air to create firefighting foam. The system consists of the foam generator, foam concentrator, atmospheric pressure foam tank and other system components such as water and foam pump(s), foam equalizer, distribution pipe made of galvanized steel zinc or equivalent corrosion resistant material, filters, valves, check- and blow-through lines, electrical and control systems. When the system is activated, the foam concentrate is mixed with water and discharged into the protected space through the foam generator. Working pressure is 6 bar with foam generator. For optimal effectiveness, it is important to mix the water-to-water concentrate in the correct ratio throughout the foaming process. This is ensured by the equalizer providing the right mix over the full operating range. The foam generator expands the foam mixture using air drawn from the protected space. Foam is discharged from the foam generator against fire hazards and completely fills the protected space. The system can be manually released from the foam room by directly operating the valves and pumps. It can also be operated remotely using a centrally located control cabinet for operational flexibility.

Activate the system

- Manually from the central foam room by directly operating the valves and pumps

- Remote control from a centrally located control cabinet with a local control cabinet for flexible operation

Extinguish Fire with High Expansion Foam

Sơ đồ tính năng hệ thống foam hệ số nở cao

The high expansion foam suppresses the fire first by separating the fuel from the air, suffocating the flame and immediately preventing further burning. The foam will then cool the upper area and reduce the evaporation of flammable vapors into the air. This is the most effective way to de-starve oxygen and cool objects on fire. High expansion foam is highly resistant to heat and smoke generated during combustion.
