Gas Fire Suppression
Clean suppression with FM200, NOVEC 1230, CO₂ & IG01 Argon
Overview
Gas fire suppression systems protect electrical/electronic spaces where water would cause damage, using clean agents or inert gases. A-Pro implements TS ISO 14520-based design, cylinder banks, nozzle layout and detection integration.
How it works
FM200 & NOVEC 1230
Clean chemical agents suppress within seconds, leave no residue, safe for electronics.
IG01 Argon (Inert)
Pure argon inert gas lowers oxygen to a fire-stopping level; natural composition with zero GWP/ODP.
CO₂ Systems
High-efficiency carbon dioxide suppression for unoccupied technical spaces and local applications.
Detection Integration
Cross-zone detector verification minimizes the risk of accidental discharge.
System types
FM200 (HFC-227ea)
Chemical clean agent; suppresses in 10 seconds at a typical 7% concentration with no residue. Compact cylinder volume ideal for small rooms.
NOVEC 1230 (FK-5-1-12)
Liquid-stored clean agent with a GWP of ~1 and a 5-day atmospheric lifetime. Offers a wide safety margin for occupied spaces.
IG01 Argon (Inert)
Pure argon; suppresses by lowering oxygen to 12–14%. Zero GWP/ODP, natural composition, suited to long pipe runs.
IG541 Inergen (Inert Blend)
Nitrogen-argon-CO₂ inert blend; the CO₂ fraction stimulates breathing as oxygen drops, improving human safety.
CO₂ Suppression
High-concentration carbon dioxide for unoccupied technical spaces and local applications only — not used in occupied areas due to its asphyxiating effect.

- Nozzle and pipe-network integrity inspection
- Audible-visual alarm and gas shut-off integration check
Frequently asked questions
Is gas suppression harmful to people?+
Systems like NOVEC 1230 and IG01 Argon are safe for occupied spaces at design concentration; CO₂ is used only in unoccupied areas.
Where is gas suppression preferred?+
In water-sensitive critical spaces such as server rooms, panel rooms, transformers and archives.
Does it leave residue?+
Clean agents (FM200, NOVEC) leave no residue; equipment keeps running without cleanup.
How often are cylinders checked?+
Annual weighing/pressure checks and periodic integrity testing per TS ISO 14520; A-Pro runs this under a maintenance contract.
Why does room tightness matter?+
The agent needs a sealed enclosure to hold design concentration long enough; this is verified with a door-fan test.
