Model 2100 Nold DeAerator

The world lost a noted inventor in 2002 with the passing of Walter Nold. With the consent of Walter and his estate, Geokon is pleased to continue Walter’s legacy by taking over the manufacture of the Nold DeAerator™.

The Nold DeAerator is designed to quickly remove dissolved gasses from liquids without the application of heat. It was developed to allow the preparation of de-aired water for use in hydraulic twin-tube piezometers and hydraulic settlement systems, where the presence of air bubbles in the connecting tubing would give rise to measurement errors.

Degassing is accomplished by means of cavitation and nucleation. Cavitation, an ultra-high vacuum, is produced behind the blades of a rotating impeller. The resulting agitation breaks up the liquid into a fine mist-like spray of particles (nucleation) from which dissolved gasses are released and can easily escape. Centrifugal forces hurl the released gasses outwards where they bubble up to an evacuated space above the liquid surface, from which they are drawn off through a vacuum tube.
