Foam Top Pourers

Delta Foam Top Pourers are integrated units designed for use in fixed foam systems for flammable liquid (hydrocarbon and polar solvent) storage protection and comprise a combined foam maker, vapour seal box and pourer.

Available in four size options with individual flow capacities from 120 to 3600 litres per minute at inlet pressures of between 3 and 10 bar each unit is pre-engineered and factory calibrated to provide precise flow and pressure characteristics. Flow rates are optimised to provide the correct minimum application rate to the specific hazard being protected. These units are available with either frangible glass or carbon impregnated low pressure 316 stainless steel Teflon burst discs which are designed to break under pressure from the foam which is then deflected onto the tank shell cooling it and gently pouring onto the fuel surface. Each unit has an easily removable cover allowing for testing of the system without breaking the seal also facilitating inspection and maintenance of the burst disc.
