Marine CO₂ Fire Extinguishing System Product Introduction

 

The shipboard CO₂ fire extinguishing system is a common and effective firefighting device widely used in critical areas of ships, such as engine rooms, cargo holds, and electronic rooms. This system works by releasing carbon dioxide gas to reduce the oxygen concentration in the fire-affected area, thereby extinguishing the fire. Since CO₂ can quickly and efficiently suppress flames without leaving any residue, it is widely used in enclosed spaces for fire suppression.

1. System Principle:The CO₂ fire extinguishing system rapidly releases high - pressure liquid CO₂ to create a high - concentration gas environment in the protected area, reducing oxygen levels (asphyxiation) and absorbing heat (cooling), thereby interrupting the combustion process. Its non - conductive and residue - free properties make it ideal for enclosed spaces or areas with sensitive equipment.

 

2. System Components:

1. CO₂ Cylinders: Store high - pressure liquid CO₂, with a capacity of 8L - 68L and a pressure resistance of 24.5MPa.

2. Cylinder Valve & Discharge Valve: Control the release of CO₂, supporting both pneumatic and manual activation.

3. Remote Control Station: Contains a nitrogen - driven bottle (4L, 5.9MPa), pressure gauge, timer, etc., enabling precise area control.

4. Fire Alarm Controller: Interacts with smoke/temperature detectors to trigger automatic fire extinguishing.

5. Distribution Pipes & Nozzles: Optimally designed to ensure uniform coverage of the protected area by CO₂.
