GEA DIOX-2 water deaeration system
GEA DIOX-2 water deaeration system
The GEA DIOX-2 is a two-stage water deaeration technology that helps to achieve the lowest possible concentration of residual oxygen in your beverage water.
Deaeration of Beverage Water
Oxygen in beverages can affect taste and can reduce shelf-life and product quality, so using deaerated water for beverage manufacture is important to help minimize the amount of oxygen in the final product.
GEA offers a range of water deaeration systems, and the GEA DIOX-2 represents an ideal two-stage vacuum deaeration unit for producing deaerated beverage water for both still and carbonated drinks. Dependent on your downstream process, and your expected residual oxygen value, the GEA DIOX-2 water deaeration system can be easily integrated into existing systems.
Two-stage vacuum deaeration for minimizing residual oxygen
The first stage of the deaeration process extracts the bulk of the oxygen using vacuum deaeration. Next, CO2 is added in to this pre-deaerated water - to promote the release of oxygen - and the water is transferred to the second stage of the process, where the CO2-oxygen mixture is drawn out by means of a vacuum pump. A discharge pump then carries the deaerated water to the next process stage.
Sealing water consumption is reduced by the integrated temperature control and can optionally be equipped with a sealing water cooler to minimize water losses.
The system is cleaned via the product path.
Features of the GEA DIOX-2 water deaeration system:
- Suitable for generating water with residual oxygen content of ≤ 0.05 mg/l (≤ 50 ppb)
- Low CO2 consumption
- Low operating costs
- Pre-assembled unit, so short installation time
- Low maintenance costs
- The CO2-free deaerated water is suitable for non-carbonated beverages
- Configurable for flow rates of between 50 hl/h and 900 hl/h
- Compact system with relatively small footprint and low height requirements compared with other deaeration systems
- Simple integration into existing systems
- Low energy demand for system operation

A new recipe for indulgence
What if your favorite chocolate didn’t require cocoa beans and your coffee was locally produced? As climate disruption, price hikes and ethical concerns hit two of our most beloved indulgences, scientists are reimagining how we produce them – using microbes, not monocultures. The goal: preserve the flavor and properties of coffee and chocolate while minimizing carbon emissions and improving food resilience.
Fueling the circular economy in shipping
Ports now compete not just on logistics, but on sustainability. At Greece’s Piraeus port, an advanced processing and recovery facility recycles ship waste oil into fuel. Equipped with GEA’s high-performance centrifuges, it sets a new benchmark for state-of-the-art, environmentally responsible port operations.
Closing the loop: key lessons for breweries from OeTTINGER
The 2022 CO2 shortage forced breweries to review their dependency on global supply chains. Many were forced to close, unable to carbonate their products. At its breweries in Germany, OeTTINGER GETRÄNKE is turning its own CO2 into a powerful lever for independence and sustainability – with the help of CO2 recovery technology from GEA.
