Total flooding is the most common system application of carbon dioxide in the marine sector for the protection of machinery spaces, machinery space control rooms, cargo pump rooms and dry cargo spaces.

If the CO2 flooding system is activated in the engine room for example, an alarm goes off warning all people to clear the engine room. Anyone in the engine room has 30 seconds (depending on the time adjustment) in which to evacuate before the ventilation louvers automatically close; the fans shut off; the fuel valves, fuel transfer pump, fuel purifier automatically shut off; and the CO2 floods the engine room.

Health & Safety requirements might require after a risk assessment, that CO2 detectors should be installed to monitor CO2 leaks, accidental CO2 release or flooding activation, or employee safe re-entry after a test release or an actual fire suppression flooding.

CO2 fire suppression applications

machinery room
electrical areas
pump rooms
generator rooms
cargo spaces
other hazards which need protection

Model SHW01 for high CO2 concentration levels (up to 45%) can be used for such applications in various versions. It can function as an air quality monitor to detect minor leaks in the suppression system as well as warning personnel not to re-enter the area without protection following a CO2 discharge.

Standard features include programmable alarm and an analogue signal output. Model SHW01 can function as a stand alone unit/system with optional alarm beacons/sirens, remote digital indication of CO2, wireless telemetry, or connected to a central control system.
