YN-CO2L-5-30 Marine Low Pressure CO₂ Fire Extinguishing System

Manufacturing Standards

1.Chapter 5 of International Code for Fire Safety Systems, as amended by MSC.206(81) and MSC. 339(91).

2.Chapter 2, Part Six of China Classification Society Rules for Classification of Sea-going Steel Ships 2025
and its amendments.

3.GB 19572—2013 Low Pressure Carbon Dioxide Extinguishing System and Components.

Application and Advantages

Large space cabins, such as car carriers, passenger and cargo ro-ro ships and large container ships, etc.
Low-pressure CO₂system is gradually being used on large car carriers, large ro-ro ships and large
container ships due to their advantages such as large storage capacity, light weight, small footprint and
short refilling time. It is intelligent monitoring and management, displays operating parameters in real
time, and features dual pressure and liquid level alarms, enabling automatic opening and closing of the
chiller. Furthermore, the system can adjust the operating time of the main and auxiliary valves based on
the size of the protected area to ensure effective fire extinguishing.
