TUW-5112 FK-5-1-12 Clean Agent

TUW-5112 FK-5-1-12 Clean Agent is a clean-agent fire suppressant built on perfluorohexanone (FK-5-1-12, perfluoro-2-methyl-3-pentanone, CAS 756-13-8). It is a clear, odourless, low-toxicity liquid with a 49.2 °C boiling point that vaporises rapidly on discharge and fills the protected space. Suppression is mainly physical cooling with some chemical inhibition, and it leaves no residue, does not conduct and does not corrode electronics — the practical difference from dry powder and HFC agents.
For consulting engineers and fire-system integrators specifying data halls and battery rooms, TUW-5112 FK-5-1-12 Clean Agent has a clean environmental profile: ODP 0, GWP about 1 and an atmospheric lifetime of five days, far better than HFC agents. Its low design concentration means fewer cylinders for the same volume, which frees up floor space. Assay is at least 99.9%; the agent is supplied in 25 kg and 250 kg drums for cylinder filling and system integration.

1. Data centres and equipment rooms — Server halls, UPS rooms, telecom shelters and modular data centres — no clean-up shutdown after discharge.
2. Battery energy storage — Lithium-ion racks, pack enclosures and containerised BESS, using total flooding to suppress thermal runaway and re-ignition.
3. Power and industry — Switchgear rooms, substations, compact substations, turbine enclosures and industrial control rooms.
4. Special collections and clean spaces — Archives, museums, laboratories, semiconductor cleanrooms and ship engine rooms.
5. Small and local applications — Handheld extinguishers, rack-level units, micro-cell sites and charging stations.

 

Systems must be engineered to code: typical design concentration 4.2–6%, discharge within 10 seconds, nitrogen-pressurised cylinders, and pipework and nozzles sized from the manufacturer's design manual. Note that this agent cannot be a drop-in re-charge for an HFC-227ea system — vapour pressure, discharge pressure and pipe sizing all differ, so the network must be recalculated.
The agent itself is low-toxicity, but thermal decomposition produces hydrogen fluoride. Force-ventilate the protected space after discharge and use respiratory protection during clean-up. Store cool and dry, out of sunlight and above the specified temperature limit, keep containers sealed, and route waste agent to a licensed disposal contractor.

 

Supplied in 25 kg and 250 kg drums, with sample packs, batch COA, SDS and third-party test reports on request. Held in stock in South China and available for cylinder fillers and fire-system integrators. TUW-5112 FK-5-1-12 Clean Agent can also be released in project batches to match site filling schedules.
