Data center fire suppression

Four families cover almost every data hall: halocarbon clean agents (FM-200 and FK-5-1-12), inert gases (nitrogen, argon and blends such as IG-541), water mist, and preaction sprinklers. Aspirating smoke detection such as VESDA sits in front of all of them and gives the earliest warning. In this table, 15 companies sell inert gas, 10 name a halocarbon agent, 11 sell water mist, 5 sell preaction sprinklers and 17 offer aspirating detection.

3M, the original maker of Novec 1230, announced in December 2022 that it would stop making all fluorinated fluids and exit PFAS manufacturing by the end of 2025. The same FK-5-1-12 agent now comes from system makers under their own names: Fike sells SF 1230 as a one-to-one drop-in Novec 1230 replacement, Minimax sells MX 1230, Rotarex builds RX5112 on FK-5-1-12, and Saval lists FK-5-1-12 “formerly Novec 1230”. Ask any bidder which fluid fills the cylinders and who supplies the refill.

Four companies publish low-noise discharge hardware. Kidde’s NATURA acoustic nozzles hold discharge below 110 dB across 500 Hz to 10 kHz, measured 1 m from the nozzle. Wagner’s FirExting SILENT, Siemens’ Sinorix Silent Extinguishing Technology and Nohmi’s PNQ/ZMQ nozzles target the same problem on inert-gas systems. Ask for the test distance and frequency band, as Kidde publishes.

Yes. Firetrace’s in-cabinet systems activate on their own and need no electricity, with an optional pressure switch to tie into emergency power off. SEVO’s SMART Cabinet FDS is a 2U, 19-inch FK-5-1-12 unit with twin optical smoke detectors. Rotarex’s FireDETEC and Minimax’s CPS 1230 protect individual cabinets as well.

No. Stat-X states that it is a condensed aerosol, not a clean agent. It is listed by UL and ULC to UL 2775, its generators have a 15-year service life, and no condensed aerosol system currently carries FM Approval. For server rooms its guidance says to shut down IT ventilation fans before release, because particles can accumulate inside equipment.

Marioff and Protec both advertise up to 90% less water; the claim is theirs, so ask for the comparator in your design. Victaulic’s Vortex discharges water and nitrogen from one emitter and says it does not need tight room integrity, with FM approval for above-raised-floor data processing halls.
