Compressed Air Foam Systems (CAFS)

For high-hazard industrial facilities, chemical plants, and municipal infrastructure, standard water and conventional foam systems can struggle to manage fast-moving, high-intensity fires. Traditional systems often require massive quantities of water and concentrate to achieve suppression, leading to extensive structural runoff, asset damage, and environmental liabilities.

DeFire USA designs, installs, and services cutting-edge Compressed Air Foam Systems (CAFS). Representing the pinnacle of modern foam technology, CAFS injects high-pressure compressed air directly into the foam-water solution, creating an incredibly dense, highly energized structural foam that smothers and cools fires up to four times faster than conventional methods.

Specialized Application Scopes

Compressed Air Foam Systems are uniquely engineered for heavy-duty industrial environments where water resources are limited or where flammable liquid hazards demand an immediate, overwhelming response:

1. Oil, Gas, and Petrochemical Storage

Application

Hydrocarbon tank farms, loading racks, and refinery process zones.

Advantage

Rapidly forms a cohesive, vapor-tight blanket over flammable liquid spills, sealing off volatile fumes and preventing atmospheric ignition.

2. Renewable Energy & Heavy Industrial Facilities

Application

Biomass plants, coal processing facilities, wood yards, and recycling centers.

Advantage

The unique clinging properties of CAFS make it ideal for deep-seated Class A fuel hazards, penetrating deeply into dense materials where water would simply run off.

3. Remote Operations & Mining Infrastructure

Application

Remote processing plants, heavy mining machinery, and off-shore assets.

Advantage

Delivers superior suppression capabilities in locations where water availability is structurally restricted or piped infrastructure is constrained.

The DeFire USA Advantage

Engineering a CAFS setup requires precise calibration of fluid dynamics, air pressure balancing, and concentrate proportioning. Miscalculating the air-to-solution ratio can result in compromised foam quality that fails during an emergency.

At DeFire USA, our high-hazard fire protection engineers utilize advanced hydraulic modeling to design fully optimized, code-compliant CAFS architectures. We integrate robust air compressors, reliable proportioners, and premium concentrates to deliver a turnkey system that guarantees maximum suppression capability with minimal asset down-time.
