CO2 FLOODING ROOMS

Overview

Electrical control rooms, DG enclosures, and industrial storage areas face one of the highest fire risks due to energized circuits, cables, oils, and flammable materials.
Traditional fire extinguishing agents like water or foam cannot be used because they damage equipment or spread electrical hazards.

That’s where CO₂ Flooding Systems by Fire Engineering Technology become the safest, fastest, and most efficient solution.

Our CO₂ Fire Suppression Systems use high-pressure or low-pressure carbon dioxide gas to extinguish fires by displacing oxygen around the flame, stopping combustion instantly and leaving no residue.
We manufacture, install, and maintain NFPA-12 compliant CO₂ flooding systems across India for industrial, commercial, and electrical applications.

🧪 How the CO₂ Flooding System Works

When a fire is detected, the system automatically releases CO₂ gas stored in pressurized cylinders through a network of nozzles.
The carbon dioxide gas quickly reduces the oxygen concentration in the protected area to below 15%, making it impossible for combustion to continue.

Within seconds, the fire is extinguished without any damage to electrical or electronic components.
Once discharged, CO₂ dissipates harmlessly into the atmosphere, ensuring quick system reset and minimal downtime.

Working stages:

1. Fire detected by heat/smoke sensor or manual trigger

2. Activation signal opens the CO₂ cylinder valve

3. CO₂ gas floods the hazard zone uniformly

4. Fire extinguished within seconds

5. Pre-discharge alarm and delay ensure human safety

🧰 Types of CO₂ Flooding Systems

🔹 High-Pressure (HP) CO₂ System

• CO₂ stored in 45 kg or 22.5 kg cylinders at ~55 bar pressure

• Suitable for small to medium enclosures such as electrical panels, DG sets, transformers, MCC rooms, and control cabinets

• Modular, compact, and easily expandable

🔹 Low-Pressure (LP) CO₂ System

• CO₂ stored in a refrigerated bulk tank at ~20 bar pressure

• Designed for large hazards or multiple connected rooms such as warehouses, conveyor systems, and storage plants

• Economical for continuous or large-volume applications

⚡ Advantages of CO₂ Fire Suppression Systems

✅ Non-conductive – safe for live electrical installations

Frequently Asked Questions (FAQ) – CO₂ Flooding System

1. What is a CO₂ Flooding System?

A CO₂ Flooding System is an automatic fire suppression system that uses carbon dioxide gas to extinguish fires by displacing oxygen around the combustion zone.
It works rapidly, leaving no residue or water damage, making it the ideal solution for electrical rooms, DG sets, transformer areas, and storage facilities.

2. How does a CO₂ Flooding System work?

When the fire detection system senses heat or smoke, it automatically triggers the release of CO₂ gas stored in high-pressure cylinders.
The CO₂ gas floods the protected area, reduces the oxygen level below 15%, and smothers the fire within seconds — without affecting electrical equipment or data.

3. Is CO₂ safe for electrical and electronic equipment?

Yes. CO₂ is a clean, non-conductive, and residue-free agent.
It causes no short circuits, corrosion, or residue, making it perfectly safe for control panels, switchgear rooms, data centers, battery rooms, and server racks.

4. What standards govern CO₂ Flooding System design?

All Fire Engineering Technology systems are designed and installed in accordance with NFPA-12, ISO 6183, and IS 15519 standards.
We also comply with local Fire Department NOC requirements and insurance approval norms for electrical and industrial applications.

5. What types of CO₂ systems are available?

There are two main system types:

• High-Pressure (HP) CO₂ System: Uses 22.5 kg or 45 kg cylinders at 55 bar for small to medium hazards.

• Low-Pressure (LP) CO₂ System: Uses refrigerated bulk tanks for large or multi-zone applications such as warehouses or storage areas.

6. Where can a CO₂ Flooding System be installed?

CO₂ Flooding Systems are ideal for:
