Model Number 1020 ERGIL Storagetech™ Foam Top Pourer Set is designed for storage tanks for fire fighting. It is designed for protecting fixed-roof (cone) and internal floating roof storage tanks. Foam Chamber is designed to introduce expanded foam directly onto the surface of a flammable or combustible liquid for fire extinguishment and/or vapor suppression. It comprises a foam generator, a foam pourer, and a vapor seal (to prevent the escape of product vapors to atmosphere through the foam line) all combined into a single fully integrated unit.
