Carbon dioxide gas extinguishing systems
CO2 High Pressure Fire Extinguishing Systems
Carbon dioxide is a non-corrosive, odorless, colorless gas. During discharge, it serves as a white mist. It does not pollute or damage the materials it touches.
Firefighting principle is two types; CO2 suffocation or oxygen dilution. It acts as CO2 suffocation or oxygen dilution. It reduces the concentration of oxygen in the region and the cooling occurs caused by the rapid expansion of the gas. Carbon dioxide should not normally be used for protecting occupied areas by people because inhalation can make asphyxia even at low concentrations. In addition, due to the formation of CO2 mist, visibility is greatly reduced during discharge. This fire extinguisher can be used in areas that are not normally used by people when appropriate safety devices are installed.
After using the fire extinguishing system, the space must be adequately ventilated because carbon dioxide is heavier than air, it accumulates in low regions. Carbon dioxide is used in high pressure plants, is stored in pressured containers up to 58.6 bar at 21 ° C. The distribution system consists of a series of 67.5 liter capacities which were tested at 250 bar and were charged using a fill factor of 0.75 kg / l or 0.67 kg / l with maximum storage temperatures of 40 ° C and 50 ° C. A series of accessories complete the system; quick flow valves, control levers, electro-pneumatic controls, manifolds, flexible hoses, nozzles, manual controls, retarding valves, sirens, etc. in order.
The cylinders can be mounted on wall brackets or can be mounted on a stand-alone metal structure. Extinguishing agent leakage tests are made by weighing. We offer a cylinder weight device, which is a special design of our company, for monitoring of the cylinder charge status.
Emission time for surface fires should not exceed 1 minute. For local applications, the discharge time must be at least 30 seconds. Integrity of any volume protected by the aggregate overflow system should be detected and effectively closed for major air leaks. The leaks can result that extinguishing agents not being able to maintain the specified level of concentration for the specified period of time.
Some of the fire extinguishing practices are listed below where CO2 is suitable.
- WPP (Wind Power Plant), HEPP (Hydroelectric Power Plants)
- SPP (Solar Power Plants), GPP (Geothermal Power Plants)
- Electrical equipment (machines, transformers, etc.)
- Painting booths, industrial furnaces, etc.
- Electronic control units and data processing centers
- Closed storage areas, dust pipes and tunnels, etc.
- Closed frame spinning machines.
- Liquid and gaseous materials
- Flammable liquid storage areas
- Engine divisions
Features and Advantages
- It doesn’t harm ozone
- Physically extinguishes
- Used for local extinguishing
- Not used in places where people live
- The cost of filling is low and it can be widely found
- The discharge time is 60-120 seconds. (30 seconds for local systems)
- Low pressure systems: Low pressure carbon dioxide systems are used in total volume protection applications where high amounts of extinguisher are needed.
- High pressure carbon dioxide systems are used for both total volume protection and local protection applications.
- CO2 is the most commonly used extinguishing gas in industrial applications.
