The Aeration Unit for Craft Brewers
The semi-automatic wort aeration system for craft brewing solutions − DN 25 up to DN 50


After cooling the wort is oxygenated to increase yeast activity and to start the fermentation process.
When the wort flows into the aeration nozzle, it creates a partial vacuum and air is entrained with the wort. This leads to an excellent bubble size distribution and thus to a large contact surface for oxygen uptake by the wort.
With the aeration unit, sterile air is introduced into the wort through the defined annular gap of the annular gap nozzle. The complete annular gap nozzle can be CIP cleaned and sterilized with steam. The system is the standard for obtaining the optimum yeast flotation and activity, and more precise fermentation curves. This guarantees superior quality beer.
