CO2 Fire Suppression System
CO2 fire suppression system works by rapidly reducing oxygen concentration. It’s a powerful solution for machinery spaces and process hazards where people are not normally present.
Overview
Where it excels
- Turbines, generators and engine rooms
- Automated process equipment and dip tanks
- Flammable liquid handling and spray booths
For occupied rooms, consider Clean Agent or Water Mist.
Key advantages
- Rapid knock-down with deep penetration into equipment
- No residue—suitable for machinery and liquids
- Cost-effective for some large-volume hazards
Safety controls
- Pre-discharge alarms and time delays
- Abort switches and lock-out procedures
- Ventilation plans and re-entry protocols
System Components
| Component | Function | Notes |
|---|---|---|
| Cylinder Banks | Store high-pressure CO₂ for rapid discharge. | Manifolds, isolation valves; weight/pressure supervision. |
| Selector Valves | Direct agent to one of multiple zones. | Interlocked to prevent misdirection. |
| Nozzles & Pipework | Deliver CO₂ to the space or equipment. | Materials sized for pressure/temperature; discharge patterns verified. |
| Releasing Panel | Detection logic, alarms, time delays, abort. | Cross-zone detection, manual release stations. |
| Interlocks | Shut down fans/conveyors; close dampers; trip fuel. | Minimizes re-ignition and protects occupants. |
| Signage & Indicators | Local warnings and system status. | Clear access control and re-entry guidance. |
Design & Safety Approach
Engineering
- Hazard classification and volume calculations
- Discharge time, concentration and hold-time targets
- Ventilation/relief and post-discharge procedures
People safety
- Audible/visual pre-discharge alarms with delay
- Abort and manual stop accessible at exits
- Lock-out/tag-out and re-entry protocols
We implement controls so the system is used in areas not normally occupied, with clearly defined evacuation procedures.
Our Delivery Workflow
1) Site Survey
Capture volumes, openings, equipment layout and shutdown options.
2) Engineering
Agent quantity, nozzle layout, interlocks, and submittals.
3) Installation
Cylinders, manifolds, piping, detection & control, warnings.
4) Commissioning
Functional tests, alarms/delays, interlock checks and training.
5) Maintenance
Inspections, weighing/pressure checks, detector testing, reports.
6) Lifecycle Support
Zone expansions, equipment changes and documentation updates.
FAQ
Is CO₂ safe for occupied spaces?
It’s designed for hazards not normally occupied. We include alarms, delays and abort to ensure evacuation before discharge.
Why choose CO₂ over clean agent?
CO₂ can be cost-effective for certain machinery/process hazards and large volumes. Clean agent is often preferred for occupied rooms with sensitive electronics.
What maintenance is required?
Periodic inspections, cylinder weight/pressure checks, detection testing and full documentation to maintain compliance.
