No Residue CO2 Fire Suppression System for Electrical Fires with 70Ltr Capacity

The CO2 Pipe Network Fire Suppression System is a high-efficiency, reliable gas fire protection solution that uses high-pressure carbon dioxide as the extinguishing agent. CO2 is distributed through a pipe network to protected zones, ensuring rapid discharge and effective fire suppression. The system is widely deployed 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 5.7 MPa, the system features 70 L cylinders with a 42 kg filling volume and a discharge time of ≤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 a wide range of project requirements.

CO2 is a clean 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.

The pipe network is constructed from 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 is an excellent fire extinguishing agent. At normal temperature it is a colorless, odorless, non-conductive, chemically neutral gas. The vapor pressure of carbon dioxide changes with temperature: as temperature rises, vapor pressure increases, and the pressure the container can withstand also increases. This system operates on a physical extinguishing principle and offers the characteristics of safety, stability, convenience, rapidity, and ease of use. All products in this series meet the requirements of the GB16669 standard and carry voluntary certification certificates.

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.

The system's startup relies on two types of drives: the electromagnetic drive and the pneumatic-handled dual-purpose drive.

• The electromagnetic drive is used for the upper cylinder.
• The pneumatic-handled dual-purpose drive is used for the main cylinder.

The system provides 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, then opens the fire extinguishing cylinder group (in a unit-independent system, the fire extinguishing cylinder is opened directly), implementing fire extinguishing in the corresponding area.
2. Manual startup — When a fire occurs in the protected area and personnel have safely evacuated, staff press the emergency startup button at the entrance of the protected area. After a 30-second delay (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 electrical startup fails, 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, 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.
