Fire Suppression

AFFF Foam Systems

Fast, Reliable Fire Suppression for High-Risk Environments

When dealing with highly flammable liquids, fire suppression isn’t just about putting out flames—it’s about stopping fire in its tracks before it spreads. Aqueous Film Forming Foam (AFFF) is a powerful fire suppression agent designed specifically for rapid knockdown and vapor suppression, making it an essential choice for airports, refineries, fuel storage facilities, and industrial sites where hydrocarbon-based fires pose a serious risk.

How AFFF Foam Systems Work

AFFF foam works by forming a thin, water-based film over the surface of flammable liquids, smothering vapors and cutting off oxygen to prevent re-ignition. Unlike water, which can spread fuel fires, AFFF rapidly suppresses flames and prevents them from growing.

Different Applications Require Different Solutions

Bladder Tank AFFF Foam Systems

AFFF systems often use bladder tanks—a simple, low-maintenance solution for storing and proportioning foam concentrate. These tanks contain a reinforced elastomeric bladder, which uses system water pressure to automatically deliver the correct foam-to-water mixture at the necessary pressure. This means:

  • No external power is required
  • Minimal maintenance is needed
  • The system delivers consistent, reliable suppression when activated
Alcohol-Resistant AFFF (AR-AFFF) Systems

Some fires require an even more advanced solution. Alcohol-Resistant AFFF (AR-AFFF) is specially formulated with polymer additives that make it effective against both hydrocarbon fires (gasoline, diesel, jet fuel) and polar solvent fires (ethanol, methanol, acetone, and other industrial alcohols).

  • Dual-purpose protection – Works on multiple fuel types, reducing the need for different suppression agents
  • Stronger stability – Forms a protective polymer barrier over polar solvents, preventing the foam from breaking down

 

Considering Foam System Integration – Getting the Mix Right

For an AFFF system to be effective, precise proportioning of foam and water is critical.

That’s why Superior Sprinkler designs systems that:

  • Use automatic pressure-balancing valves to maintain the correct mix
  • Are tailored to your specific fuel hazards and site layout
  • Are engineered for reliability, ensuring rapid suppression when needed.
