Unitor High Pressure CO2 Fire Extinguishing System 

Cost effective solution for closed spaces
Unitor High Pressure CO2 Fire Extinguishing System (Unitor CO2 System) is a total flooding system using CO2 gas recovered from an industrial process, making it kinder to the environment. The system is proven to be a fast and effective solution on deep seated fires in cargo holds, and it has been supplied to hundreds of vessels worldwide over the past few years.

The system is designed as total flooding system for machinery spaces of Category A, engine rooms, pump rooms and cargo holds onboard vessels or on offshore installations which needs fire protection.

Local systems for paint lockers and galley ducting are available and smoke smapling system for cargo holds can be incorporated.

Unitor CO2 System has pressure operated cylinder top valves to quickly discharge the CO2 gas. This ensures almost instantaneous extinguishing of the fire to effectively protect the area. A manual release system is available and is designed to individually release the CO2 cylinders one by one, or by group in sequence depending upon the state of fires.
