It extinguishes fires using CO2 by suppressing the oxygen content in the space. The CO2gas has proven to be a fast acting fire extinguishing agent and is effective on deep seated fires in cargo holds.
Local systems for paint lockers and galley ducting are available and smoke sampling systems for cargo holds can also be incorporated in the CO2 system package.
Features and benefits
- Fast fire extinguishing system
- Effective on deep-seated fires in engine rooms, pump rooms and cargo holds
- Type approved extinguishing system
- Safety release delay designed for crew security
- Can utilise CO2 gas distribution piping to cargo holds for smoke sampling
- Effective on deep-seated fires in engine rooms, pump rooms and cargo holds
- CO2 has an Ozone Depletion Potential (ODP) of zero and a Global Warming Potential (GWP) of 1
- Uses CO2 gas recovered from an industrial process – kinder to the environment
- Rack modules ( cylinders, manifolds and discharge hoses ) can be supplied as option.
Technical Design
The system consists of a high pressure cylinder bank with either manual or pressure operated cylinder top valves.
The cylinder bank and a unique manifold are stored in their own insulated room. Valves are connected to the manifold using flexible high pressure hoses.
From main distribution valves, a piping system is used to distribute the gas to the discharge nozzles which are placed uniformly
throughout the protected spaces. The system is operated manually from a release cabinet located centrally, or from release cabinets placed close to the protected space.
When releasing the system, the main distribution valve opens while simultaneously the pilot gas to the pressure operated CO2 cylinder top valves is delayed for a specified time. After the delay, the cylinder top valves open and the gas is discharged through the piping and nozzles into the protected space.
The cylinders with manifolds and discharge hoses can be delivered assembled in rack modules. The system can also be complemented by Unitor Local Application Fire Fighting System for providing total fire protection for engine room.
