Electrically Actuated Ceiling-Mounted FK-5-1-12 Suppression Unit

1. System Overview

FK-5-1-12 (Perfluorohexanone) is one of the most widely used clean agent fire extinguishing media in the international market today. Its extinguishing mechanism is primarily based on physical heat absorption, and it exhibits extremely high chemical stability along with excellent environmental characteristics. FK-5-1-12 is non-conductive and non-corrosive, and it does not cause damage to precision equipment. After discharge, it vaporizes rapidly and leaves no residue, making it a globally recommended, environmentally friendly clean-agent fire suppression solution for high-end applications.

The electrically actuated ceiling-mounted FK-5-1-12 clean agent extinguishing unit is a pre-engineered, self-contained system in which the clean agent and the nitrogen propellant are stored together within the same cylinder. When a fire occurs, the agent is discharged directly into the protected enclosure under the pressure of the nitrogen propellant, achieving rapid extinguishment.

This type of unit is suitable for protection of individual enclosures. It features a compact configuration, simplified installation, no requirement for complex piping networks, and low overall system cost.

2. Key Advantages

Safe, Non-Toxic, and Personnel-Friendly

FK-5-1-12 offers a high margin of safety and allows short-term human exposure at design concentration without adverse effects. It does not generate corrosive or hazardous by-products after discharge, enabling occupants to evacuate quickly and safely.

Ultra-Low Environmental Impact

• ODP (Ozone Depletion Potential) = 0

• GWP (Global Warming Potential) ≈ 1, one of the lowest among all clean agents

• Atmospheric lifetime of approximately 5 days, making it the most environmentally benign fire-extinguishing chemical currently available in the international market.

Clean and Residue‑Free:

No powder or liquid residue after discharge; no contamination of equipment.

Ideal for environments requiring high cleanliness such as data centers, archives, and laboratories.

High Suppression Efficiency

• Discharge time ≤ 10 seconds, achieving suppression concentration within a very short period.

• Utilizes the total flooding method, capable of rapidly suppression Class A, Class B, and electrical fires.

Mature and Reliable System

• Well-established technical standards.

• Compact equipment configuration, strong system interlocks, and simplified maintenance and management.

3. How It Works

The extinguishing mechanism of FK-5-1-12 is a combined process of heat absorption and interruption of the combustion chain reaction.

When a fire occurs, the fire extinguishing control system receives the actuation signal and energizes the electric actuator connected to the container valve. The high-pressure nitrogen propellant drives the FK-5-1-12 clean agent out of the storage cylinder, releasing it through the cabinet-mounted nozzle. The agent rapidly disperses throughout the protected enclosure to suppress the fire.

FK-5-1-12 extinguishes fire through the following mechanisms:

• Absorbs a large amount of heat, rapidly reducing flame temperature.

• Interrupts the combustion chain reaction, preventing further flame propagation.

• Provides slight oxygen dilution, enhancing the overall extinguishing performance.

With its extremely rapid dispersion characteristics, the agent can reach the design extinguishing concentration within seconds, ensuring a fast, safe, and complete clean-agent suppression effect..
