De-aired water or antifreeze solutions are an essential ingredient of any hydraulic piezometer or settlement system, where the formation of air bubbles in the fluid-filled tubing must be prevented. The Nold DeAerator provides a rapid means of removing dissolved gases from fluids, at a much higher rate than through conventional heating/boiling methods. The Nold DeAerator consists of a holding tank, which can be evacuated using either a vacuum pump or a water-powered aspirator. Water (or antifreeze solution), is drawn into the tank where it is agitated violently by a rotating impeller, causing cavitation, nucleation and the rapid expulsion of the dissolved gasses. The Nold DeAerator can also be used with other fluids to remove dissolved gasses.
