CO2 Flooding System

A CO2 flooding system uses carbon dioxide as the fire-extinguishing agent. When released, the gas expands and reduces the oxygen available to the fire. CO2 is effective for a range of fire hazards, but exposure during discharge can be dangerous because it reduces oxygen levels. That is why these systems are designed with alarms and delays, and used where people can be kept clear. Essatech supplies, installs and services CO2 flooding systems in Hyderabad and Visakhapatnam, including automatic CO2 flooding systems, fixed CO2 fire-fighting systems and gas suppression systems.

The system is designed to suit the site conditions and the importance of the data or materials that need protection. The number of CO2 cylinders depends on the location being protected. Gas is routed under pressure through mild steel (MS) pipes and tubes. Essatech supplies CO2 gas and also offers FM200 flooding systems. The choice of fire suppression system depends on the hazard. Foam flooding is used for petroleum products, while CO2 flooding may be used for electrical fires depending on the circumstances.

A CO2 flooding system can operate through a panel or a fire trace tube. In a panel-operated system, fire or smoke detection triggers the release of CO2 through a solenoid valve. The fire alarm panel controls the release in response to detection, after a pre-discharge alarm and a delay that give people time to leave.

A fire trace tube connects to the extinguisher cylinder. It has a closed end and is kept under high pressure. When exposed to fire, the tube expands and bursts at the hot spot, and this releases the gas to control the fire. It needs no electricity or detector, which makes it useful for small enclosures, remote equipment and vehicles.

CO2 flooding systems are used to protect capacitor banks, cable trays and ducts. Fire trace applications also include:

We supply, install and service CO2 systems as a complete job:

A CO2 discharge can be dangerous to anyone inside. We design for safety with a pre-discharge alarm, a time delay, door signs and lock-off valves for maintenance, and we advise a clean agent instead where people work in the room.

A CO2 system must be ready on the day. At each service visit we weigh or check the cylinders, test the release mechanism and the alarm and delay, inspect pipework and nozzles for damage or blockage, and confirm the door signs and lock-off valves are in place. A cylinder that has lost gas is refilled, so the system always holds its full design quantity.

Industries with cable galleries, battery rooms, capacitor banks and switchgear are the main users, because people are rarely inside. Builders and architects should show these rooms with their openings, so we can plan sealing and a safe exit with door signs. Commercial building owners and hospital owners with electrical rooms should use CO2 only where nobody works, and choose a clean agent elsewhere. MEP consultants can share the electrical room drawings and we calculate cylinders and pipework. Corporates use it in unoccupied electrical areas. Defence sites, including Navy and Army power plants, generator rooms and cable galleries, use CO2, and we quote within their security and vendor rules.
