Delta Foam Top Pourers

The Delta Foam Top Pourers are designed for fixed roof tank foam systems containing flammable liquids. As with many items from Delta’s fixed foam equipment range the Top Pourers are manufactured to clients individual specifications and factory calibrated for optimum performance.

Each of Delta Foam Top Pourers from Delta’s foam equipment range has a combined foam maker, vapour seal box and pourer. These units can be flow tested in situ without contamination of the products in the tank. Delta Foam Top Pourer sets come in four sizes with individual capacities from 120 to 3600 litres per minute.

Individual units are pre-engineered to give precise flow and pressure characteristics. These flow rates are optimised to provide the correct minimum application rate to the hazard being protected.

The Foam Top Pourers have a frangible glass seal which breaks under pressure from the foam that is then deflected onto the tank shell cooling it and gently pouring it onto the fuel surface. The Delta Foam Top Pourer sets all have an easily removable cover allowing for system testing without the need to break the seal and facilitating inspection and maintenance. Individual performance curves are available upon request for each of the four models.

A special adaptor fixing kit is available from Delta’s foam equipment range to enable external tank fixing. The kit consists of a special flange adaptor with fixed threaded studs. An appropriate ANSI 150lb flange size hole is cut into the tank shell and the adaptor is bolted into place. The Foam Top Pourer Set flange can then be easily offered up to the locating studs and fastened into position-all nuts, washers and gaskets are provided. The Foam Top Pourers form part of Delta Fire’s dedicated range of fixed foam equipment and are manufactured in the UK under an ISO 9001 Quality System.
