Product Description

Product Description

High-Pressure CO2 Fire Extinguishing System

The High-Pressure CO2 Fire Extinguishing System is a total-flooding clean agent solution designed for unmanned or normally unoccupied protected spaces. CO2 provides rapid knockdown, leaves no residue, and does not damage electrical or precision equipment. The skid/stand design integrates cylinders, driving gas set, manifold and control for fast installation and commissioning.

System Composition (Main Assemblies)

CO2 agent cylinder set (70/80 L), container valve, siphon tube, weight-check device
Nitrogen driving cylinder set with valve, pressure gauge
High-pressure flexible hoses, manifold (DN32–DN150)
Selector valves (threaded ≤DN80; flanged ≥DN100) for multi-zone systems
Gas & liquid check valves, low-leakage high-seal valve
Nozzles & nozzle covers (DN20–DN50)
Signal feedback device, solenoid actuator (DC24 V), pneumatic actuator

Compliance & Standards
Designed and inspected according to GB 25972-2010 and related national codes; pressure parts and valves follow corresponding GB/TSG requirements.

Ordering Information
