- CO2 leaves no residue to be cleaned up after extinguishment of fire. Therefore the equipment that has not been damaged by fire can be re-used at once.

- NK's versatile and unigue actuating devices enable simple and reliable actuation of the carbon dioxide extinguishing system. By the use of copper tube for the control lines, the cost of the actuating system is extremely low.

- NK carbon dioxide extinguishing systems have been approved by principal countries' governmental authorities and classification societies and equipped on over a thousand ships.


















- Total Flooding System for Engine Room, Pump Room, Cargo Holds, etc.
The total flooding system is designed to discharge at least 85% of the total quantity of CO2 required for the protected space within two minutes so that any fires in the space can be extinguished immediately.
The total flooding system is the best method which allows the carbon dioxide extinguishing system to fully exhibit its advantages.

- The semi-tatal flooding system is also available.
The semi-total flooding system is suited for the cargo space loading the self-propelled vehicles, and is capable of discharging two thirds of the total quantity of CO2 required for this particular space within ten minutes.

- Manual Release system for cargo Holds ;
The nature of fires can vary with cargoes and range from surface fires to deep-seated ones.
The manual release system is designed to individually release the CO2 cylinders one by one or by group in sequence depending upon the state of fires.
