Water Deaerating Systems
GEA VARIDOX-C cold water deaeration system
Oxygen in beer or beverages may increase product perishability and spoil taste, so using optimally deaerated water for beverage manufacture and for the redilution of beer can have an impact on final quality. The GEA VARIDOX-C cold water deaeration system achieves very low residual oxygen levels, and can be used for different applications.
Deaeration of beverage water
The water is sprayed in the deaeration column and it slowly trickles down the packed columns. At the column outlet the water is saturated with CO2 (N2). If the water is to be used for blending a carbonated product, a precarbonation option is available, configured with a second, separate CO2 line that feeds CO2 to the deaerated water (after the deaeration column).
The system includes probes for flow rate, water or CIP media levels, and, optionally, for oxygen. These sensors monitor the system and how it is functioning. The product line and column are cleaned directly by an efficient CIP system.
Features
- Low residual oxygen content: <0.03 mg/l (30 ppb)
- Residual oxygen content of: <0.02 mg/l (20 ppb) and <0.01 mg/l (10 ppb), achievable, dependent on configured column height
- Low CO2 consumption
- Low operating costs, when compared with technology for deaeration under vacuum
- Short installation time (the unit is pre-assembled)
- Low maintenance costs
- Can be supplied for flow rates between 20 hl/h and 1,000 hl/h

Alcohol-free beer: They want it all – they want less
There was a time when the phrases ‘non-alcoholic beer’ and ‘tastes good’ were seldom used together in the same sentence, particularly by consumers. But low-proof and alcohol-free beers have come a long way – many of them now refreshing drinks in their own right – thanks in no small part to technology from GEA.
