KETTON CLEAN AGENT FIRE SUPPRESSION SYSTEMS

UL Listed Clean Agent Fire Suppression Systems

1.What is a Clean Agent Fire Suppression System?

  A clean agent fire suppression system is an engineered gaseous fire protection system designed for enclosed hazards where water, foam or dry chemical extinguishing methods may damage equipment, interrupt operations or leave contamination. The agent is stored in cylinders and released through a pipe network and nozzles to create a design concentration inside the protected room. KETTON clean agent systems are designed for facilities where rapid suppression, clean discharge and protection of high-value assets are critical. The systems can be integrated with addressable fire detection, extinguishing release panels, manual controls and monitoring devices.

2. Available Clean Agent Technologies

FM-200® / HFC-227ea

FM-200 is the common commercial name associated with HFC-227ea, a halocarbon clean agent stored as a liquefied compressed gas. It suppresses fire primarily by absorbing heat from the flame zone and reducing the ability of the combustion reaction to continue. It is electrically non-conductive, leaves no residue and is widely used in data centres, server rooms and electrical spaces.

Novec™ 1230 / FK-5-1-12

Novec 1230 is commonly associated with FK-5-1-12 clean agent technology. It is stored as a liquid and discharged as a gas. It provides rapid suppression, clean discharge and an excellent environmental profile, making it a strong choice for projects with sustainability requirements and sensitive assets.

3. How the System Works

1. Smoke or fire detection devices identify a confirmed fire condition.
2. The release panel activates alarms and starts any programmed delay.
3. Ventilation shutdown, dampers and warning devices operate as required by the design.
4. The cylinder valve is released electrically, pneumatically or manually.
5. Agent flows through the manifold, pipework and nozzles into the protected enclosure.
6. The room reaches design concentration and the fire is suppressed.
7. Post-discharge inspection, ventilation and system recharge are completed by competent personnel.

4. Key Benefits

• Fast fire suppression for critical hazards
• No water damage and no powder clean-up
• Electrically non-conductive agents for sensitive electronics
• Reduced business interruption after system operation
• Suitable for normally occupied spaces when properly designed
• Flexible single-zone and multi-zone configurations
• Compatible with professional detection and releasing systems
• Supported by hydraulic calculation and project documentation

5. Typical Applications

Data Centres and Server Rooms

Clean agents protect servers, storage equipment and network infrastructure without water damage or residue. Fast suppression helps reduce downtime and protects business continuity.

Electrical Switch Rooms

Electrically non-conductive agents are suitable for electrical environments where water-based suppression could create secondary damage or safety concerns.

UPS and Battery Rooms

Critical power rooms require fast suppression and careful engineering. Enclosure integrity, ventilation shutdown and hazard-specific design review are essential.

Telecommunication Facilities

Telecom spaces require continuous operation and reliable protection for sensitive electronic equipment, cables, racks and control systems.

Control Rooms

Process control rooms, SCADA rooms and automation spaces contain high-value equipment that must remain clean and operational after a fire event.

Museums and Archives

Clean agents are well suited to areas containing documents, artefacts and collections because they leave no water, foam or powder residue.

Healthcare and Laboratories

Medical equipment rooms and laboratories require clean fire protection where contamination and long clean-up times are unacceptable.

Oil, Gas and Industrial Facilities

Clean agent systems can protect enclosed electrical rooms, control cabinets, analyzer rooms and other critical indoor hazards within industrial sites.

6. Available Cylinder Sizes

KETTON systems are available with multiple cylinder families. Final cylinder selection is based on protected volume, selected agent, design concentration, pipe network, available cylinder room space and hydraulic calculation.

7. Engineering Design and Project Support

Clean agent systems must be engineered for each protected enclosure. The correct agent quantity, cylinder capacity, pipe diameter, nozzle arrangement and discharge characteristics must be verified by design calculation and approved documentation.

• Room volume and hazard classification review
• Agent quantity and design concentration calculation
• Hydraulic calculation and pressure loss verification
• Pipe sizing, nozzle selection and discharge time verification
• Cylinder quantity, capacity and pressure series selection
• Room integrity review and hold-time considerations
• CAD layout, bill of materials and project submittal support
• Commissioning, maintenance and recharging support
