A room integrity test is mandatory
85% of the extinguishing concentration must be held in the space for at least 10 minutes. Even a gap under the door can render the system useless.
Gaseous Fire Suppression
Ten seconds from detection to full suppression. No residue, no damage, minimal downtime.
Agent families — system options
Four agents, four different needs
The heart of the system is the chosen agent. Select one — its full dossier opens below.
Novec 1230
“a gas stored as a liquid”Leaves no residue on electronics, does not conduct electricity, and breaks down in the atmosphere within 5 days. The most future-proof, safest choice for occupied spaces and data centers.
How does it extinguish?
On discharge it vaporizes and absorbs heat from the flame at the molecular level; the combustion chain is broken.
The Science →Technical specifications
- FK-5-1-12
- Design concentration 6.1% — NOAEL 10% → 64% safety margin
- Discharge ≤10 sec · 42 bar
- 30–50 m² protection per nozzle
- GWP<1 · atmospheric lifetime 5 days · ODP 0
FM-200
“the proven classic”The most widely used clean suppression agent in the world. A strong option for upgrading existing systems and for retrofit.
How does it extinguish?
Heat absorption plus suppression of flame radicals. Its active compound has been used in asthma inhalers since 1942.
The Science →Technical specifications
- HFC-227ea
- Discharge ≤10 sec · compact storage
- Design concentration within NOAEL — approved for occupied spaces
- GWP ~2100+ · atmospheric lifetime ~32 years
- EU F-Gas restrictions are tightening — assessed alongside its alternatives
High-Pressure CO₂
“industrial power”The oldest and most economical gaseous solution. Installed only in unoccupied spaces, with a strict safety interlock chain.
How does it extinguish?
Dilutes oxygen to a level where combustion cannot be sustained; creates strong cooling as it expands.
The Science →Technical specifications
- Design concentration lethal to humans — lockout, warning, and delay are mandatory
- Tank capacity up to 150 tons
- Transformers, cable galleries, industrial areas
Inert (IG series)
“nature itself”Nitrogen and argon blends. Zero environmental impact, safe for people, economical in large volumes.
How does it extinguish?
Dilutes oxygen to the ~12–13% band: the fire goes out, people keep breathing — equivalent to 3,500 m of altitude.
The Science →Technical specifications
- Blends: IG-01 / IG-55 / IG-100 / IG-541 (per project)
- GWP 0 · ODP 0
- Post-discharge O₂ within the range safe for people

- Novec 123064% margin
- FM-200Positive margin
- HFC-125Zero margin
- CO₂Design concentration lethal (unoccupied spaces)
