AMS Water Degasser for water degassing


AMS water degassing and beverage degassing solutions focus on Gas Stripping with either hot or cold degassing solutions.

Attainable residual oxygen in the degassed water may be less than 0.02mg (ppm) O2/litre or less than 20µg (ppb) O2/litre.
The value for the residual oxygen is dependent on the oxygen content and the temperature of the raw water. The cooling of the water should therefore always take place after the water degassing. The column diameter and the column height are determined based on water temperature, oxygen content in the raw water, the desired throughput rate and the permitted residual oxygen.


The degassing process takes place completely at the temperature of the incoming water. This process always has the lowest energy consumption with the same output even though the column is the highest. The plant is extremely robust and there are hardly any wearing parts. The plant can be manufactured economically for many different sizes. Even for very small outputs.
Downstream UV sterilisation must be integrated if there are problems with the hygiene of the raw water. If severe problems with water hygiene are anticipated, then preference should be given to pasteurisation.
Gas requirement:  approx. 0.22 kg/hl water, amount lost:  approx. 5% (rest remains in the water)

- UV sterilisation


Hot degassing offers the benefit of additional pasteurisation and is the ideal choice if problems with water hygiene are anticipated. Little energy is required for operating the plant due to the high level of heat recovery. The water enters the plant cold and leaves it cold as well. The increase in temperature due to pasteurisation is only approx. 8°C even if no cooling zone is provided in the heat exchanger (available as an option). In principle, no CIP cleaning or sterilisation is required due to the hot operation and the internal sterilisation steps during start-up. Acid cleaning should only be carried out occasionally depending on the hardness of the water.
Gas requirement: approx. 0.10 kg/hl water, approx. 5% of this is lost (via the roof, rest remains in the water)
AMS HOT DEGAS is available in 8 standard series for each capacity.

The AMS JUICE DEGAS is a high-end module for degassing of any fruit juice.
The degassing takes place on a rotating plate within an evacuated tank, the rotation of the plate allows the product to be flung evenly against the tank wall forming a thin film. The vacuum separates the gases from the product film which are sucked out. A specific quantity of steam is removed depending on the set temperature. This steam and the contained flavours are condensed in a heat exchanger and then directly fed back into the product. The components which cannot be condensed are removed from the system with a vacuum pump.
