Data Sheet<br />
Description<br />
Oxygen in beer or beverages may spoil the perishability and taste. It is therefore important to use<br />
optimum deaerated water for the production of beverages and for the redilution of beer. The<br />
innovative <strong>GEA</strong> <strong>Diessel</strong> water deaeration system <strong>VARIDOX</strong>-H achieves with hot deaeration<br />
excellent residual oxygen values which makes it most suitable for this and other applications.<br />
With 72°C the water is fed to the deaerating column and slowly trickles down the packed columns.<br />
The high temperature strongly reduces the solubility of the oxygen in the water. The bottom-up<br />
flowing CO2 (N2) ensures an additional release of the oxygen.<br />
When the water is cooled down a heat recovery of > 90 % is obtained by means of the<br />
regenerating step. In another step the water is cooled down to the desired temperature.<br />
The sensors for flow rate, level, and optionally oxygen monitor the <strong>VARIDOX</strong> as to its proper<br />
function.<br />
<strong>VARIDOX</strong> is cleaned on the product way.<br />
Special features:<br />
- residual oxygen content ≤ 0.02 mg O2/l (option ≤ 0.01 mgO2/l)<br />
- low running costs<br />
- low wear and tear<br />
- pasteurization of water (≥ 25 PE)<br />
- works-tested unit<br />
- capacities of 5,000 – 80,000 l/h available<br />
