QME70 carbon dioxide （CO2）fire extinguishing system

PRODUCT DETAILS

Overview

The QME70 Carbon Dioxide (CO2) Fire Extinguishing System is designed for protecting valuable assets and high-risk areas by using CO2 as the primary extinguishing agent. This system is highly effective in controlling fires, particularly in spaces where water-based suppression systems may not be suitable. The CO2 system works by reducing the oxygen level in the protected area, suffocating the fire, and stopping its ability to sustain combustion.

QME70 is ideal for use in enclosed spaces or areas where sensitive equipment, electrical systems, or materials could be damaged by water or other agents. The system consists of a CO2 storage cylinder bank, pressure regulation devices, delivery pipelines, nozzles, and control systems. It is engineered for both manual and automatic activation, providing reliable, fast, and efficient fire suppression.

Fire Extinguishing Principle

The QME70 CO2 Fire Extinguishing System operates by discharging carbon dioxide gas into the protected area, rapidly lowering the oxygen concentration. Once activated, the CO2 gas is released from the storage cylinders through a network of pipes and nozzles, filling the area and quickly reducing the oxygen level below the threshold needed to support combustion. This effectively suppresses the fire, preventing further burning.

The system typically works automatically, where fire detectors in the protected area sense a fire, trigger an alarm, and activate the release of CO2 after a brief delay. In cases of manual activation, operators can trigger the system through control panels. The system can be designed for both total flooding (for complete room protection) and local application (targeting specific areas).

Application Scope

The QME70 CO2 Fire Extinguishing System is suitable for protecting areas where traditional water-based systems would cause damage or be ineffective. It is commonly used in the following applications:

Electrical and electronic equipment rooms: To protect sensitive electrical equipment, such as control rooms, data centers, and server rooms, where water could damage machinery.
Transformer rooms: To safeguard electrical transformers and other critical power distribution equipment.
Oil and gas facilities: In spaces where flammable liquids, gases, or vapors are present.
Telecommunication and computer rooms: For protecting telecommunications equipment and IT infrastructure.
Power generation plants: For ensuring fire safety in critical areas such as generators, switchgear, and control panels.
Specialized archives and storage facilities: Such as museums, libraries, or archives containing sensitive paper documents, books, and other materials.
Hazardous material storage rooms: Including chemical storage and flammable liquid storage areas where other extinguishing agents may not be suitable.

This system is also ideal for areas where human presence is minimal during normal operation but could be critical in an emergency, such as remote or unoccupied industrial facilities.
