In enclosed or large-volume spaces where traditional firefighting methods struggle to reach, High Expansion Foam (HEF) is the ultimate solution. Engineered by INFERNO GLOBAL SOLUTIONS, our High Expansion Foam rapidly fills confined areas with a thick, air-expanded foam blanket that smothers fire, displaces oxygen, and prevents reignition—while using significantly less water.
This foam is ideal for tunnels, basements, aircraft hangars, mines, ship holds, and other environments where visibility, accessibility, and fire spread are major concerns.
🌊 What is High Expansion Foam?
High Expansion Foam is a specialized firefighting agent that expands between 200:1 and 1000:1 when mixed with air and water. This means one liter of concentrate can produce hundreds of liters of foam, making it the most efficient agent in terms of volume coverage.
HEF doesn’t just smother fires—it fills space, creating a physical barrier between the fire and oxygen.
🔥 Key Features & Benefits
