70L Capacity 42kg Gas Filling Volume CO2 Fire Suppression System with 5.7MPa Work Stress for Electrical Fires

High-pressure carbon dioxide fire extinguishing system

System Composition:
  The CO2 Pipe Network Fire Suppression System is a high-efficiency and reliable gas fire protection solution using high-pressure carbon dioxide as the extinguishing agent. The system distributes CO2 through a pipe network to protected zones, ensuring rapid discharge and effective fire suppression. It is widely used in data centers, server rooms, electrical substations, power distribution rooms, marine engine rooms, industrial plants, paint spraying rooms, boiler rooms, and warehouses.

  Designed with a working pressure of 5.7MPa, the system features 70L cylinders with a 42kg filling volume and a discharge time ≤60 seconds, enabling fast and powerful fire suppression. It supports single-zone or multi-zone protection, allowing flexible configuration of cylinder banks and pipe layouts to meet various project requirements.

  CO2 is a clean fire extinguishing agent with no residue, non-conductive properties, and no water damage, making it ideal for protecting sensitive equipment and electrical installations. The system offers automatic, manual, and mechanical emergency release modes and can be equipped with a DC24V solenoid valve for stable and reliable activation.

System Features:

  The pipe network is made of high-pressure galvanized steel pipes with flange connections, ensuring excellent strength and long-term durability. Optional leakage alarm and remote monitoring functions provide real-time cylinder pressure status, enhancing operational safety and reducing maintenance costs.

  
  Carbon dioxide gas is an excellent fire extinguishing agent. Its chemical formula is CO. At normal temperature, it is a colorless, odorless, non-conductive, chemically neutral, corrosive and toxic gas. The vapor pressure of carbon dioxide changes with temperature. As the temperature rises, the vapor pressure increases. In a fixed container, as the temperature rises, the pressure that the container can withstand also increases. This fire extinguishing system belongs to physical fire extinguishing. It has the characteristics of safety, stability, convenience, rapidity and ease of use. This series of products all meet the requirements of GB16669 standard and have voluntary certification certificates.

Application scope:
  The CO2 Pipe Network Fire Suppression System is suitable for extinguishing electrical fires, flammable liquid fires, and gas fires where power can be cut off. It is widely applied in the power industry, petrochemical industry, telecommunications sector, transportation facilities, and marine engineering. With fast response, high extinguishing efficiency, and reliable performance, it delivers professional fire protection for critical assets.

Working principle:


Startup methods:
  The system's startup relies on two types of drives, namely the electromagnetic drive and the pneumatic-handled dual-purpose drive.
1. The electromagnetic drive is used for the upper bottle.
2. The pneumatic-handled dual-purpose drive is used for the main cylinder.

  The system has four specific startup methods: automatic startup, manual startup, mechanical startup, and emergency mechanical startup.
1. Automatic startup - When two different types of detectors (usually smoke and temperature combined) in the protected area simultaneously send out fire alarm signals, the fire alarm controller delays for 30 seconds (0-305 adjustable), and sends an electrical signal to activate the corresponding area's startup cylinder. The startup gas first opens the selection valve of the corresponding area, and then opens the fire extinguishing cylinder group (in a unit-independent system, the fire extinguishing cylinder is directly opened), implementing fire extinguishing in the corresponding area.
2. Manual startup - When a fire occurs in the protected area and the personnel have safely evacuated, the staff presses the emergency startup button at the entrance of the protected area, and delays for 30 seconds (0-30 seconds adjustable). The fire alarm controller sends an electrical signal to activate the corresponding area's startup cylinder, implementing fire extinguishing in the corresponding area.
3. Mechanical startup - When the electrical startup fire extinguishing fails, the staff can mechanically start the corresponding area's startup cylinder in the cylinder room to implement fire extinguishing in the corresponding area.
4. Emergency mechanical startup - When the above three startup methods fail, the staff can manually open the corresponding selection valve and the active cylinder head valve in the cylinder room respectively to implement fire extinguishing in the corresponding area.
