When it comes to protecting critical assets like data centers, server rooms, telecommunications facilities, and control rooms, two clean agent fire suppression systems stand out as industry favorites: Novec 1230 and FM200 (HFC-227ea) .
Both are excellent choices. Both are clean, residue-free, and safe for occupied spaces. Both are approved by international standards (NFPA 2001, ISO 14520).
But when it comes down to a decision: Which one is actually better?
The honest answer? It depends on your priorities.
XINGJIN Fire, a specialized manufacturer of both FM200 and Novec 1230 systems with 16 years of experience, provides this objective comparison to help you make an informed decision.
Quick Overview: What Are Novec 1230 and FM200?
| Aspect | FM200 (HFC-227ea) | Novec 1230 |
|---|---|---|
| Chemical family | Hydrofluorocarbon (HFC) | Fluoroketone (FK) |
| Appearance | Colorless, odorless gas | Colorless, odorless liquid (vaporizes on discharge) |
| Extinguishing mechanism | Heat absorption + chemical interruption | Primarily heat absorption |
| Storage pressure | ~42 bar (600 psi) | ~42 bar (600 psi) |
| Discharge time | ≤ 10 seconds | ≤ 10 seconds |
| Design concentration | 6.25% – 9% (Class A/B hazards) | 4.5% – 6% (Class A/B hazards) |
Both agents are clean — meaning they leave no residue after discharge, making them ideal for protecting sensitive electronic equipment.
Comparison 1: Environmental Impact
Which is greener?
| Environmental Metric | FM200 | Novec 1230 |
|---|---|---|
| Ozone Depletion Potential (ODP) | 0 | 0 |
| Global Warming Potential (GWP) | ~3,500 | ~1 |
| Atmospheric lifetime | ~36 years | ~5 days |
| Regulatory status | Being phased down under Kigali Amendment | No phase-down restrictions |
Winner: Novec 1230
Novec 1230 has a significantly lower global warming potential (1 vs. 3,500) and an atmospheric lifetime of just 5 days — compared to 36 years for FM200. For facilities pursuing green building certifications (LEED, BREEAM) or operating under strict environmental regulations, Novec 1230 is the clear winner.
What This Means for You:
-
If your facility is in a region with strict HFC regulations (Europe, some parts of Asia), Novec 1230 offers long-term regulatory security.
-
If environmental impact is a key decision factor for your organization, Novec 1230 is the superior choice.
Comparison 2: Human Safety
Which is safer for occupied spaces?
| Safety Factor | FM200 | Novec 1230 |
|---|---|---|
| NOAEL (safe concentration) | 9% by volume | 10% by volume |
| LOAEL (dangerous concentration) | 10.5% | >10.5% |
| Typical design concentration | 6.25% – 9% | 4.5% – 6% |
| Decomposition products | Hydrogen fluoride (HF) possible at high temperatures | Hydrogen fluoride (HF) possible at high temperatures |
| Safety margin | Good | Excellent |
Winner: Novec 1230 (slightly)
Both agents are safe for occupied spaces when properly designed. However, Novec 1230 offers a wider safety margin — it can be used at lower concentrations (as low as 4.5% for Class A hazards) and has a higher NOAEL (10% vs. 9%).
What This Means for You:
-
For most applications, both agents are equally safe for occupied spaces.
-
For facilities with higher occupancy or more sensitive populations, Novec 1230's wider safety margin provides extra peace of mind.
Comparison 3: Fire Suppression Performance
Which extinguishes fires faster and more effectively?
| Performance Factor | FM200 | Novec 1230 |
|---|---|---|
| Extinguishing speed | ≤ 10 seconds | ≤ 10 seconds |
| Required concentration | Higher (6.25-9%) | Lower (4.5-6%) |
| Agent quantity needed | More (because higher concentration) | Less (because lower concentration) |
| Effectiveness on Class A fires | Excellent | Excellent |
| Effectiveness on Class B fires | Excellent | Excellent |
| Effectiveness on electrical fires | Excellent (non-conductive) | Excellent (non-conductive) |
Winner: Tie
Both agents are highly effective at extinguishing Class A (ordinary combustibles), Class B (flammable liquids), and electrical fires. The key difference is that Novec 1230 achieves extinguishment at lower concentrations — meaning you need less agent to protect the same space.
What This Means for You:
-
Less agent means smaller cylinders or fewer cylinders — potentially reducing storage space requirements.
-
Lower concentration also means slightly lower risk of decomposition byproducts in extreme fire scenarios.
Comparison 4: Equipment Protection
