co2 fire suppression system

Within industrial and commercial environments where sensitive equipment is located, the need for effective firefighting systems is essential to ensure safety and security.

The co2 fire suppression system using carbon dioxide gas is one of the ideal solutions, as this system works to extinguish fires very effectively by reducing the percentage of oxygen in the fire and lowering its temperature.

Which quickly extinguishes fires without causing damage to equipment or leaving harmful residues. The CO2 system is used in a variety of applications such as generator rooms, laboratories, and industrial facilities due to its great ability to protect lives and property.

In this article, we will talk about how the CO2 system works, its benefits, areas of use, and its importance in maintaining the safety of various sectors through the United Group, the exclusive and only agent for the Emirati Watex fire pump.

What is a CO2 fire extinguishing system? 

Carbon dioxide gas is a gas that does not conduct heat and is not flammable, which makes it effective in controlling fires. The fire fighting system using carbon dioxide gas is distinguished by its ability to put out the fire without causing any damage to property, and it does not require cleaning after controlling the fire. .

 

The co2 fire suppression system works by releasing an amount of carbon dioxide gas, which reduces oxygen gas, the main element in continuing combustion, which contributes to extinguishing the fire effectively.

 

Carbon dioxide fire extinguishers are available in different sizes, so it is best to consult specialists to determine the appropriate size to best protect your property.

Design of CO2 fire extinguishing system

The co2 fire suppression system using carbon dioxide gas is designed in a precise way that requires a good understanding. The design begins with assessing the risks and identifying sensitive areas that need special protection, such as generator rooms, laboratories, and industrial facilities.

 

The size and type of extinguishers are determined based on the size of the space and the type of flammable materials. The design includes the installation of CO2 gas cylinders.

Under high pressure with carefully designed distribution networks to ensure that the gas is effectively directed towards the fire area.

The systems are equipped with advanced sensors to detect fire and release gas automatically when needed. Audio and light alarm systems are also designed to respond to individuals when there is a fire.

The design must include appropriate ventilation passages to discharge the gas after extinguishing and ensure that people are not exposed to dangerous levels of CO2. In addition, clear instructions and periodic training must be provided to users to ensure the system operates efficiently.

Through these integrated components, the co2 fire suppression system using carbon dioxide gas provides protection for facilities and installations, which leads to reducing the damage that can occur to lives and property.

CO2 fire extinguishing system components

• Carbon dioxide gas cylinders: The number and size of cylinders are determined according to the size of the room to be extinguished using hydraulic calculations according to the NFPA code.
• Gas discharge piping network: The diameters of the piping network are determined according to the engineering design and hydraulic calculations that determine the number of nozzles in the room.
• Fire extinguishing panel and sensors: It is responsible for receiving the signal from the sensors and sending it to the electromagnetic valve to complete the unloading process.
• Alarm wiring and pipe network.
• Fire alarm siren.
• Fire alarm bell.
• Manual operating device.
• Stop switch.
• Scale for carbon dioxide cylinders.

Why co2 extinguishers without indicator

Under a pressure of approximately 55 bar and a temperature of 20 degrees Celsius, the fire extinguisher is filled with carbon dioxide gas, which turns the gas into a liquid state known as liquefied CO2, and sometimes into dry ice. This liquid turns into a gas as soon as there is space that allows it to expand.

When using the extinguisher, any amount released is compensated by converting a similar amount of liquid into gas, which keeps the pressure always constant inside the cylinder for this reason.

It is not useful to install a pressure indicator in these extinguishers because the liquid will remain constant, and the only way to check the CO2 content of the extinguisher is to measure its weight periodically.

How to install a CO2 system

The process of installing a co2 fire suppression system begins with determining the needs of the system based on the size and type of the room and The area to be protected, determines the number and size of CO2 cylinders required using hydraulic calculations and NFPA code standards to ensure the proper amount of gas is supplied to efficiently extinguish the fire.

The network of pipes designated for discharging the gas is installed, and its diameters are determined based on the engineering design and hydraulic calculations to ensure appropriate gas distribution.

Installing the system's control panel, which receives signals from the accounts and directs them to the electromagnetic valve to start the unloading process when a fire is detected.

It also installs a network of wires and pipes for the alarm, which includes a siren and a fire alarm bell To alert Individuals in the area, the co2 fire suppression system includes a manual operating device and a stop switch to allow By manually controlling the unloading process when needed.

A scale is installed For cylinders CO2 to monitor gas levels and ensure the availability of a sufficient quantity when needed. This arrangement ensures that the system is ready in the event of an emergency, which contributes to the protection of facilities and individuals.

How to install CO2 cylinders

The process of installing carbon dioxide cylinders begins with determining the appropriate location, as the location must be easily accessible and safe, away from sources of heat and moisture.

Then the co2 fire suppression system cylinders are installed using stands or clips to ensure stability and stability. It is necessary to secure the cylinders tightly to avoid tipping or movement while providing sufficient distance to facilitate maintenance and inspection.

After installing the cylinders, they are connected to the piping system designed to transport gas. The pipes are installed in a manner that complies with safety and pressure standards, and all connections and switches must be ensured to avoid leaks.

The system is tested to ensure that there are no leaks and to ensure its proper operation. It is also necessary to ensure that all parts are compatible with the NFPA code and international standards, and periodic checks are conducted to ensure that the co2 fire suppression system works efficiently in emergency situations.
