## Clean Agent Fire Extinguishing System

Clean agents are **ozone-depleting-free replacements for halon**. This clean agent extinguishes fires by **extracting heat** rather than reducing oxygen levels, making it an ideal gaseous extinguishing medium. Additionally, clean agent gas leaves no residue, making this product suitable for electrical/electronic equipment rooms.

**Key Advantages:**

- **Liquid at ambient temperature and pressure** — no high-pressure cylinder storage required; cylinder operating pressure is low.
- **Residue-free and non-conductive after discharge** — protects sensitive electronic equipment. **FK-5-1-12 (perfluorohexanone)** exhibits excellent dielectric properties and is non-corrosive to most metals, rubber, and plastics.
- **High personnel safety margin** — significant gap between the design extinguishing concentration and the **NOAEL (No Observed Adverse Effect Level)**.
- **Extinguishing mechanism**: Acts through **chemical inhibition** to interrupt the combustion chain reaction, enabling rapid fire suppression. It also provides a strong **heat-absorbing cooling effect**, effectively preventing re-ignition.
