High Expansion foam generators are designed to expand foam into a large volume of stable bubbles with expansion rates up to 595:1- 837:1. This high performance is achieved without any external power source or moving parts, which gives advantages for installation and reduces ongoing maintenance requirements. High Expansion Foam Systems are commonly used on hazards such as ordinary combustibles and hydrocarbon ignitable liquids. Such hazards are commonly found in applications such as aircraft hangars, warehouses, cable tunnels, underground storage or recycling plants.

Designers and estimators can use the innovative “HiEx Foam Estimator” tool to assist with calculating the number of generators and amount of concentrate needed for NFPA 409 and UFC projects, along with the HiEx Generator Assembly guide.
