Gas Suppression Systems
We provide Design, Supply, Installation, Testing & Commissioning services for Fire Alarm Systems as per NFPA72 Standards. Our systems meet EN54, UL & FM design approvals.
Brands We Work With: Tyco Ansul, Kidde, Cryptzo, Honeywell, UTC, Siemens, Fire Trace, Kannex, etc.
Key Concepts
- Principle of Operation
- Fire Suppression: Reduces oxygen, inhibits chemical reactions, or cools flames.
- Clean Agent Gases: No residue; safe for equipment.
- Types of Fire Suppression Gases
- Chemical Agents:
- FM-200 (HFC-227ea): Absorbs heat and disrupts combustion.
- Novec 1230: Environmentally friendly, absorbs heat.
- Inergen: Blend of Nitrogen, Argon, and CO2; reduces oxygen levels.
- CO2 (Carbon Dioxide): Displaces oxygen; used in unoccupied spaces.
- Inert Gases:
- Inergen (IG-541): Nitrogen, Argon, and CO2 mix.
- Argonite (IG-55): Argon and nitrogen mix.
- Nitrogen: For environments with volatile substances.
- Chemical Agents:
Components of a Gas Suppression System
- Control Panel: Detects fires and activates gas release.
- Fire Detectors: Smoke, heat, or flame detectors.
- Gas Storage Cylinders: Store suppression gas under pressure.
- Pipework & Nozzles: Distributes gas through pipes.
- Manual Activation Stations: Allow manual system discharge.
- Warning Devices: Visual and audible alarms.
Common Applications
- Data Centers, Archives, Telecommunications Rooms, Power Generation Plants, and Marine Applications.
Design Considerations
- Room Sealing: Ensure airtightness for effective gas concentration.
- Discharge Time: Rapid discharge (10-60 seconds) to suppress fire.
- Human Safety: FM-200 and Novec 1230 are safe for occupied spaces; CO2 for unoccupied areas.
- Ventilation: Proper ventilation after discharge.
Fire Detection and Activation
- Automatic Activation: Linked to detection systems.
- Manual Activation: For emergency personnel use.
Maintenance and Testing
- Regular Inspections: Check cylinders, system integrity, and detectors.
- Room Integrity Testing: Ensure the room holds gas concentration.
Advantages of Gas Suppression Systems
No Residue, Rapid Response, and Minimal Damage.
Disadvantages
Cost, Room Integrity Requirements, and Safety Concerns (CO2 systems).
