Low-pressure CO₂ systems are designed for fire protection of large machinery spaces and cargo holds that require carbon dioxide fire suppression.Compared with traditional high-pressure cylinder solutions, the core advantage of this low-pressure system is that a single storage tank can replace a large quantity of high-pressure CO₂ cylinders, reducing the overall equipment weight by approximately 50%. The storage tank, main valves, distribution valves, refrigeration equipment, cooling units and matching control components are all pre-assembled and pre-wired, integrally mounted on an integrated steel base frame for direct on-site installation upon delivery.
An electronic level gauge is equipped to display the real-time tonnage of CO₂ stored inside the tank intuitively. The gauge is fitted with low-level alarm contacts to automatically trigger warnings when the remaining fire suppressant in the tank is insufficient. Refilling after discharge is convenient, as the tank can be directly recharged via a tanker truck.
For large vessel projects, the overall installation cost of a low-pressure CO₂ system is far lower than that of a high-pressure cylinder-type system. Furthermore, the whole system is engineered to fully comply with the standards and requirements of the classification society the vessel is constructed to meet.
