Oxygen in beer or beverages may harm the durability and taste. It is therefore important to use optimum deaerated water for the production of beverages and for the redilution of beer.
The innovative water deaeration system VARIDOX-H achieves excellent residual oxygen values with hot deaeration, which makes it most suitable for this and other applications. With 72 °C the water is fed to the de-aerating column and slowly trickles down the packed columns. The high temperature strongly reduces the solubility of the oxygen in the water. The bottom-up flowing CO2 (N2) ensures an additional release of the oxygen. When the water is cooled down a heat recovery of approx. 90 % is obtained by means of the regenerating step. In another step the water is cooled down to the desired temperature. The sensors for flow rate, level, and optionally oxygen monitor the VARIDOX as to its proper function. The water deaeration system VARIDOX is cleaned on the product way.
