Impeller Systems

Impeller systems provide a high mixing efficiency and very fine gas bubbles for increased activity.

During a very short treatment time dissolved hydrogen, density index and oxides can be reduced to target values.

Impeller systems are used often for a last treatment of the liquid aluminum before casting.

The gas regulation based on our Mass Flow Controller flox[on] B guarantees process control through fast and repeatable flow regulation also under difficult conditions. Flow and pressure through the Impeller or the Porous Plug are monitored continuously, so that critical process conditions could be indicated early. The level of automatization enables an automatic or semi-automatic treatment of the liquid aluminium.

Advantages:

• repeatable treatment process

• reliable process

• early failure indication

• accuracy in temperature distribution

• increase of homogenization

• increased aluminium quality

• process automatization
