Vahutõrjesüsteeme

Vahutõrjesüsteeme are fire suppression systems that utilize foam concentrate mixed with water to extinguish fires. These systems are particularly effective for Class B fires, which involve flammable liquids like gasoline, oil, and alcohol, as well as for Class A fires involving ordinary combustibles. The foam works by creating a blanket over the burning material, which cools the fuel, suppresses the release of combustible vapors, and prevents re-ignition by separating the fuel from the oxygen.

The core components of a vahutõrjesüsteem typically include a water supply, a foam proportioner that accurately mixes water and foam concentrate, a foam storage tank or source of concentrate, and a discharge system. The discharge system can consist of specialized nozzles, monitors, or sprinklers designed to distribute the foam effectively over the fire area. Depending on the application, these systems can be fixed installations or portable units.

Vahutõrjesüsteeme are commonly found in locations where flammable liquids are stored or processed, such as fuel storage depots, aircraft hangars, chemical plants, and industrial facilities. They are also used in marine applications, including on oil rigs and in ship engine rooms. The selection of the appropriate foam concentrate and system design depends on the specific hazards present and the type of fuel involved. Different types of foam concentrates exist, including AFFF (Aqueous Film-Forming Foam), FFFP (Film-Forming Fluoroprotein), and AR-AFFF (Alcohol-Resistant Aqueous Film-Forming Foam), each suited for different fuel types and fire conditions. Regular maintenance and testing are crucial to ensure the reliable operation of these life-saving systems.
