High-Pressure Carbon Dioxide Fire Extinguishing System

1. System Overview

The high-pressure carbon dioxide (CO₂) fire extinguishing system is a highly efficient and clean gaseous fire suppression system that utilizes both smothering and cooling mechanisms for extinguishment. Carbon dioxide is a naturally occurring, non-conductive, colorless, and odorless gas that leaves no residue after discharge, ensuring that sensitive equipment, cultural property, and electrical installations are not damaged.

The CO₂ fire extinguishing system has been widely recognized internationally and is particularly suitable for suppressing fires involving flammable liquids, flammable gases, and energized electrical equipment. The system is especially appropriate for the protection of high-risk and high-value areas where post-discharge cleanliness is critically important.

The high-pressure, piping-network CO₂ system can be configured with selector valves to distribute the extinguishing agent to multiple zones. A single system can provide fire protection for several independent hazards, significantly improving suppression efficiency and system cost-effectiveness.

2. Key Advantages

High-Efficiency and Reliable Fire Suppression

• Carbon dioxide rapidly reduces oxygen concentration, achieving fire extinguishment by smothering.

• Provides significant cooling, making it suitable for multiple classes of fire hazards.

Clean Agent with No Residue

• Fully vaporizes after discharge, leaving no solid or liquid residues, and does not contaminate equipment or the environment.

• Suitable for clean-sensitive areas such as spray-painting booths, transformer rooms, and electrical distribution rooms.

Safe for Equipment

• Non-conductive and non-corrosive, and does not interfere with the normal operation of precision instruments or electronic equipment.

• No cleanup is required after discharge, reducing system recovery time.

Economical and Practical

• Carbon dioxide is widely available and low-cost to recharge.

• The system uses mature technology, is easy to maintain, and has a long service life.

Environmentally Compliant

• Does not deplete the ozone layer; ODP = 0.

• GWP = 1, resulting in extremely low global warming impact, fully compliant with international environmental conventions.

3. How It Works

The high-pressure carbon dioxide fire extinguishing system achieves fire suppression primarily through smothering and cooling mechanisms.
When a fire occurs, the control system is activated, releasing CO₂ rapidly from the storage cylinders and conveying it through the piping network into the protected enclosure. The extinguishing mechanisms include:

1. Dilution of oxygen concentration, reducing the oxygen level in the combustion zone below the limit required to sustain combustion.

2. Absorption of a large amount of heat, lowering the temperature of burning materials.

The system can reach the design concentration within seconds, enabling rapid fire suppression while providing occupants with adequate time for safe evacuation.

6.Typical Applications

The high-pressure carbon dioxide fire extinguishing system is particularly suitable for the following applications:

• Electrical facilities: substations, electrical distribution rooms, generator rooms

• Industrial environments: spray-painting booths, oil storage areas, chemical storage zones

• Data centers and telecommunications rooms

• Ship engine rooms and offshore platforms

• Printing plants, paper mills, and grain storage facilities

• Laboratories and research centers

In summary, any enclosed or semi-enclosed space containing hazards involving flammable solids, flammable liquids, or energized electrical equipment—and requiring clean, non-residue fire suppression—is an ideal application for a high-pressure CO₂ system (excluding normally occupied spaces).
