Foam Maker

EMA Foam Maker is being used for the most common applications of protecting tank seal in vertical liquid storage tank with internal floating roof with low expansion foam system. The application of aspirated foam is on the basis of the risk comprising the area in the annular ring between the rim of the floating roof and the tank shell. EMA Foam system design guidelines generally used are in accordance with NFPA11 standard. EMA Foam Makers are defined by NFPA 11 as Type II discharge outlets for delivering the low expansion aspirated foam to the seal. EMA Foam Makers are widely used with the Inline Foam Inductor,Balance Pressure Foam Proportioning system, Bladder Tank system and Foam tenders.

Foam Maker is an air aspirating foam generator connected to the foam pourer to deliver the aspirated foam gently into the tank seal area. Foam maker covers wide range of foam solution rates from 75 to 557 litres per minute at 2.8 to 7 kg/sq.cm. inlet pressure. The orifice is field replaceable in the event of change in design parameters. The foam is produced by introducing air into the foam solution stream. The inlet of foam maker is designed to create venture jet which draws air into the foam solution stream
