CO2 EXTINGUISHING SYSTEMS
Fast and Effective Fire Extinguishing
Features
In particular, carbon dioxide extinguishing systems require effective protection of the protected objects in the event of a fire, minimizing operational interruptions after a fire, preventing reactions between the burned substance and the extinguishing agent, preventing damage from the extinguishing agent and effectively extinguishing objects in hard-to-reach areas (3D extinguishing effect). Suitable for high risk areas.
The required amount of extinguishing agent depends on the size and surface of the protection zone, the quality (eg gas tightness) and type of areas to be protected. While the extinguishing nozzles themselves are evenly distributed over the entire raid area, the pipe network size and the location of the extinguishing nozzles depend on the risk area.
The carbon dioxide extinguishing process reduces the oxygen in the air of the protected area to a level well below the natural level of 21% by volume. Carbon dioxide in concentrations that can extinguish fires can be harmful to life, so special safety precautions must be taken.
High-Pressure Systems (High-Pressure Systems)
High-pressure steel cylinders are combined in a cylinder center in a special frame with an independent suspension system at the installation location. Large assemblies of gas cylinders, arranged in one or more rows, can surprisingly be stored in a very small space.
Special frames can be easily adapted for larger protection zones or for quick replacement of individual cylinders. Each cylinder hanger is also a weighing unit that automatically indicates the minimum leakage of extinguishing agent.
Control functions and components of the extinguishing system, such as gas quantity, shut-off, release and distribution units, are monitored to ensure that the extinguishing system is always ready for functionality.
Low-Pressure Systems (High-Pressure Systems)
If a large amount of extinguishing agent is required for the sake of the overall safety concept, low pressure tanks are recommended, especially from an economic point of view. Liquefied carbon dioxide is stored in this tank at approximately –20 °C and an operating pressure of approximately 20 bar.
A refrigeration unit provides a constant low temperature. Operating costs are minimized thanks to the optimum insulation design. The storage tank is mounted on a calibable electronic weighing system that continuously displays the actual weight and thus any possible gas loss due to leakage.
