Fire Suppression – Gas Based (FK 5-1-12 & Inert Gas)
Suppress the Fire. Protect the Asset. Leave No Trace.
Gas-based fire suppression systems are the gold standard for protecting high-value, mission-critical environments where water or powder would cause as much damage as the fire itself. Digitech designs, supplies, and installs clean agent suppression systems using FK 5-1-12 (Novec 1230) and inert gas agents (IG-541, IG-55, IG-100) for server rooms, data centres, control rooms, archives, and electrical switchrooms. Every system is designed by certified fire protection engineers to NFPA 2001 and ISO 14520 standards, with full integration into your fire detection and alarm platform.
Choosing the Right Suppression Agent
Digitech specifies and installs the most appropriate gas suppression agent based on your enclosure size, occupancy, environmental requirements, and regulatory obligations:
FK 5-1-12 (Novec 1230 / Chemours)
Fluoroketone clean agent with zero ozone depletion potential, ultra-low global warming potential, and rapid fire suppression without leaving residue or damaging equipment.
HFC-227ea (FM-200)
Proven hydrofluorocarbon clean agent with fast suppression speed, compact cylinder storage, and wide international approval for IT and electrical fire protection.
IG-541 (Inergen)
Blend of nitrogen, argon, and CO2 naturally reducing oxygen levels to suppress fire while remaining breathable for short-term human exposure during evacuation.
IG-55 (Argonite)
50/50 nitrogen and argon blend — a zero global warming potential inert gas agent ideal for large volumes and environmentally sensitive applications.
IG-100 (Nitrogen)
Pure nitrogen suppression for large enclosures and industrial environments where cost, availability, and environmental impact are primary selection criteria.
CO2 Systems
High-concentration CO2 total flooding for unmanned electrical rooms, cable tunnels, and industrial equipment where complete oxygen displacement is acceptable.
Chemical Clean Agents vs Inert Gas Systems
The choice between chemical clean agents and inert gas systems involves trade-offs in suppression speed, storage footprint, environmental credentials, and suitability for occupied spaces.
Chemical Clean Agents (FK 5-1-12, FM-200)
Faster suppression at lower agent concentrations, smaller cylinder storage requirement, and suitable for occupied areas — but higher material cost per kg
Inert Gas Systems (IG-541, IG-55, IG-100)
Zero global warming potential, naturally derived agents, and suitability for larger enclosures — but requiring larger cylinder banks and higher storage space.
Selection Criteria
Enclosure volume, occupancy status, cylinder storage space, environmental policy, budget, and local regulatory approval all influence agent selection — Digitech provides independent specification advice.
What Your Gas Suppression System Can Do
- Total flooding design achieving the required extinguishing concentration uniformly throughout the protected enclosure within 10 seconds of discharge.
- Automatic actuation on confirmed detection with programmable time delay for safe evacuation before agent release commences.
- Abort switch and manual release at the protected room entrance for emergency override of automatic discharge in occupied spaces.
- Enclosure integrity testing (door fan testing) prior to commissioning to verify that agent concentration can be maintained for the required hold time.
- Agent quantity management with cylinder pressure monitoring and automatic low-agent alerts indicating when recharge is required.
- Post-discharge ventilation system integration to safely purge suppression agent from the protected space after fire control is confirmed.
- Full compliance documentation including design calculations, isometric drawings, and commissioning certificates to NFPA 2001 and ISO 14520.
