Pressurized dry powder fire protection systems offer an advanced solution for fire suppression, delivering power-based extinguishing agents quickly and precisely.
These systems are particularly effective against a wide range of fire types because of the chemical properties of the powder and the dispersion method.
Pressurized dry powder fire suppression systems consist of a network of pipes, nozzles, and tanks containing the extinguishing agent, often accompanied by a propellant such as nitrogen or carbon dioxide.
When the system is activated, either manually or automatically via fire detection sensors, the propellant gas releases the powder from the extinguisher, which is then dispersed over the fire.
The suppression mechanism is based on a combined action:
These systems are particularly suited for extinguishing fires involving flames, oils, hydrocarbons, or cryogenic gases, due to their chemical reaction with these substances.
Pressurized dry powder systems offer several key benefits that make them more suitable in certain situations than other fire protection technologies such as water, foam, or gas systems.
They are highly effective against a wide range of fires, particularly electrical fires, for which water or foam systems are unsuitable.
The powder is non-conductive, making it safe to use on electrical fires involving live equipment.
Pressurized dry powder systems provide rapid fire suppression, extinguishing the flames in a very short time.
The force with which the powder is expelled also creates a mechanical suppression effect on the flames.
The versatility of dry powder extinguishing agents and the effectiveness of pressurized distribution systems make them suitable for a wide range of applications. They are widely used to fight fires across different classes:
Used in sectors such as chemical, petroleum, pharmaceutical, food and energy to combat fires involving flammable liquids and gases.
Ideal for handling fires involving flammable liquids and gases in ATEX zones and environments with combustible dust.
Designed to protect storage areas containing materials with chemical compositions that are difficult to extinguish.
