The Three Clean Agents Explained

Halon vs Halotron vs Cleanguard

Performance, Cost, Environment, and Why Each One Matters

Daniel Beauchesne stocks and recycles all three. This is the technical breakdown so you understand what you're actually choosing between, not just what's cheaper.

Why We Can't Just Use Halon Anymore

Halon 1211 is the best fire extinguisher ever made. Period. It's the gold standard. Military uses it. Aerospace uses it. Pilots keep it in cockpits. The problem: it was banned from production in 1994 because it depletes the ozone layer.

The Montreal Protocol identified Halon as a Class I ozone-depleting substance. Using Halon doesn't help the ozone layer recover. You can still buy and USE existing Halon stock—it's been produced since the 1960s and we have decades of supply. But making new Halon is illegal in most countries.

This created a market problem: the best extinguisher is no longer made, but existing stock is legal and valuable. Enter Halotron and Cleanguard—designed as Halon replacements that actually work on Class A, B, and C fires without the environmental penalty.

What They Actually Are: The Chemistry

Understanding what these agents are chemically helps explain why they perform differently and why environmental impact varies so much.

Halon 1211 (CBrClF₂)

Chemical Type

Chlorofluorocarbon (CFC). Old technology developed in the 1960s. Contains bromine, which attacks the ozone layer.

How It Works

Chemical reaction + heat absorption. Interrupts the fire's chemical chain reaction while cooling the burning material.

Production Status

BANNED from new production (1994). Existing stock is legal and valuable.

Ozone Depletion Potential (ODP)

7.9 (high). For comparison, CFC-11 = 1.0. Halon is 7.9 times worse for the ozone layer.

Global Warming Potential (GWP)

1,890 (high). Halon is a potent greenhouse gas if released to the atmosphere.

Availability

Limited. Existing stock gets recycled and recertified. We buy, recycle, and recharge Halon extinguishers.

Halotron I (HCFC-123)

Chemical Type

Hydrochlorofluorocarbon (HCFC). Newer than Halon, designed as a Halon replacement. Contains chlorine (less ozone-depleting than bromine).

How It Works

Similar to Halon. Chemical reaction + cooling. Nearly identical fire suppression performance.

Production Status

Still produced. EPA approved. Phase-out scheduled for 2030, but still widely available.

Ozone Depletion Potential (ODP)

0.0098 (very low). 800 times LESS ozone-depleting than Halon. Much better for the ozone layer.

Global Warming Potential (GWP)

77 (low). About 25 times LESS warming potential than Halon. Much better for climate.

Availability

Readily available. Manufactured by Amerex. Common for new installs. Good pricing.

Cleanguard (FE-36 / HFC-236fa)

Chemical Type

Hydrofluorocarbon (HFC). Newest of the three. Contains fluorine but NO chlorine or bromine. Zero ozone depletion.

How It Works

Comparable performance and efficiency to Halon 1211. Chemical reaction + cooling. Nearly identical to Halon.

Production Status

Still produced. EPA approved. No scheduled phase-out. Long-term availability.

Ozone Depletion Potential (ODP)

0 (zero). No ozone depletion whatsoever. Environmentally safe for the ozone layer.

Global Warming Potential (GWP)

9,820 (high). Higher GWP than Halotron and Halon. Climate concern if released.

Availability

Available. Manufactured by Chemours (Ansul brand). Slightly higher cost than Halotron.

Performance: Which One Actually Puts Out Fires Better?

This is where it gets real. The U.S. military tested all three against each other. Here's what they found.

Military Testing: F-100 Engine-Nacelle Test

The U.S. Air Force tested Halon 1211 replacements using a standard F-100 Engine-Nacelle Test Fixture at Tyndall Air Force Base. Three candidate systems were tested: DuPont's FE-36 (Cleanguard) with Ansul hardware, and Halotron I with two different hardware combinations.

The test created three simultaneous fires: a spray fire within the fixture (fuel ignited from nozzles), burning fuel flowing out of the fixture, and a pool fire beneath the fixture. The goal was to match Halon 1211 performance.

Result: Both Cleanguard and Halotron matched Halon 1211 performance in most scenarios. No clear winner. All three extinguished the test fires effectively. The difference came down to discharge time and reach—not raw effectiveness.

Real-World Insight: One Critical Difference

Pilots who've used both report: Halon floods better. Meaning, in hidden fires (fires you can't see directly), Halon disperses more effectively throughout the space.

Halotron requires a slightly larger quantity to achieve the same result in hidden fire scenarios. In direct application (you can see and aim at the fire), all three perform nearly identically.

Practical implication: For most hand-portable extinguisher uses (office, boat, vehicle, data center), performance is effectively the same. The Halon advantage matters mainly in fixed suppression systems and aircraft where hidden fires are common.

🎯 Performance Bottom Line:

All three (Halon, Halotron, Cleanguard) put out Class A, B, and C fires effectively. Halon has a slight edge in hidden fire suppression. For your hand-portable extinguisher, pick based on cost and environmental impact, not performance—they're too similar to matter.

Environmental Impact: Where They Actually Differ

Performance is nearly identical. Environmental impact? Vastly different. This is why the industry moved away from Halon.

Halon 1211

Ozone Depletion

ODP: 7.9

7.9 times worse for ozone than reference compound. If released, damages ozone layer.

Climate Impact

GWP: 1,890

Potent greenhouse gas. Warming effect 1,890 times that of CO2 over 100 years.

Halotron I

Ozone Depletion

ODP: 0.0098

800 times LESS ozone-depleting than Halon. Minimal ozone layer impact.

Climate Impact

GWP: 77

Much lower. 25 times LESS warming potential than Halon. Much better for climate.

Cleanguard

Ozone Depletion

ODP: 0

ZERO ozone depletion. Safe for the ozone layer. No environmental concern here.

Climate Impact

GWP: 9,820

High. 5 times WORSE than Halon for climate. Biggest concern for global warming.

The Environmental Trade-off

Halon: Bad for ozone layer AND climate. Banned for a reason. But existing stock is legal and valuable.

Halotron: Good for ozone layer. Acceptable for climate. The balanced choice. Not perfect, but much better than Halon and less controversial than Cleanguard.

Cleanguard: Perfect for ozone layer. Bad for climate (highest GWP). The choice if environmental activists are watching. The choice if you prioritize global warming over ozone.

Which One Should YOU Choose?

Performance is essentially identical. Cost varies. Environmental impact varies. Here's how to decide.

Pick Halon 1211 If:

  • Money is no object. You want the absolute best and cost doesn't matter.
  • You're protecting critical military or aerospace equipment. Where Halon's superior flooding performance matters.
  • You have existing Halon that needs recertification. We recycle and recertify existing stock. Keep using what works.
  • You're okay with higher environmental impact. You acknowledge it's not ideal but accept it for performance.

Pick Halotron I If:

  • You want the best balance of performance, cost, and environment. Not perfect on either, but good on all three.
  • You're stocking multiple units. Cost difference adds up. Halotron is cheapest per unit.
  • You want long-term availability. Still in production. No phase-out scheduled. Future-proof choice.
  • You're a dealer stocking inventory. Halotron is the smart choice to stock. Best customer value proposition.

Pick Cleanguard If:

  • Ozone depletion is your primary concern. Zero ODP. The environmentally responsible choice for the ozone layer.
  • You need to meet strict environmental compliance. Your facility mandates zero-ODP agents.
  • You're willing to pay a premium for environmental leadership. Cleanguard costs more but sends a message.
  • Performance needs to match Halon as closely as possible. Cleanguard is closest to Halon 1211 in actual fire suppression.

🎯 Our Recommendation:

For most applications (boats, electronics, data centers, offices): Halotron I. Best value. Good environmental profile. Readily available. If you already have Halon, keep it and recycle/recertify it through us. If you need zero-ODP, go Cleanguard. If you want the absolute best, get Halon—but expect to pay for it.

Real-World: Where Each One Makes Sense

🚤 Boat Engine Compartment

Pick: Halon or Cleanguard (if you have the budget). Why: Boats have fuel, oil, AND sensitive electronics. In salt water. You need non-residue agents. Halon performs slightly better in confined spaces. Cleanguard costs less but still works. Halotron works too if budget is tight.

💻 Data Center / Server Room

Pick: Halotron or Cleanguard (either works equally well). Why: You need zero residue. Both perform equivalently on electronics fires. Halotron is cheaper. Cleanguard is environmentally superior. Can't go wrong with either. Halon is overkill for this application.

🛩️ Aircraft / Cockpit

Pick: Halon (if you can afford it). Why: Aircraft experience hidden fires (wiring, fuel, oil in confined spaces). Halon's superior flooding performance matters here. Halotron and Cleanguard work but require slightly more agent. Pilots who've used both prefer Halon.

🏢 Office / Retail (Protecting Electronics)

Pick: Halotron (best value). Why: Offices have electronics but not extreme hidden fire risk. Halotron costs less, performs adequately, still available long-term. For 90% of businesses, this is the right choice.

🌍 "We Care About the Environment"

Pick: Cleanguard (zero ODP). Why: If environmental responsibility is your brand story, Cleanguard proves it. Yes, it costs more and has higher GWP, but zero ozone depletion is the headline. Halotron is the practical middle ground.
