ANSUL - High-Expansion Foam Agents

Foam Concentrates with expansion ratios up to 1000:1 for suppression of Class A and Class B fire in large volume spaces. High-Expansion foam concentrates produce flexible firefighting foams for suppression of Class A and Class B fires in large-volume spaces such as aircraft hangars or warehouse storage. When discharged through well-designed high-expansion generators, these foams can achieve expansion ratios up to 1000:1, rapidly forming substantial volumes that contain minimal water. These foams can quickly fill over-sized rooms and enclosures, effectively suppressing horizontal and vertical (three-dimensional) fires while minimizing water damage. High-Expansion foams are also used to protect outdoor LNG storage areas, where they can quickly blanket the flammable liquid surface for fire and vapor suppression.
