Cold Degassing System CWD

Simple and efficientOur cold water degassing (CWD) system combines simplicity, process reliability, and efficiency to achieve the highest product quality while minimizing environmental impact. The stripping process results in low oxygen levels, and since a significant portion of the CO2 binds to the water, there is minimal loss.

How does the CWD work?
At the top of the column, incoming water is precisely distributed to the structured packing of the water degassing system. At this point, the deaeration process begins where the water gently trickles down through the packing, counter to the upward movement of the supplied CO2 at the column sump.

The secret behind this process lies in the special structure of our high-performance packing, which ensures an extremely intense contact between the water and the stripping gas, effectively saturating the water with CO2 while efficiently removing oxygen from it. If necessary, nitrogen can even be used as the stripping gas to adjust the process.

The degassed water is then pumped out of the column sump and can be cooled through a heat exchanger. It can then either be directly supplied to a consumer or stored in a buffer tank for immediate use. This efficient system ensures that we can deliver the highest-quality water in a way that combines simplicity, safety, and efficiency.

Why should you choose the CWD?

  • Best oxygen values: ur system ensure a good product quality with oxygen values of less than 50 ppb, and values as low as <10 ppb possible depending on the configuration.
  • Low CO2 consumption: Since a significant portion of the CO2 used dissolves in the water, the loss is minimal, at approximately 0.4 g/l CO2.
  • Complete clean concept: Our system is designed for comprehensive and effective cleaning, including CO2 lines.
  • Energy efficiency: Thanks to the FLOW ADAPT algorithm, degassing performance adapts to the fill level in the buffer tank, saving energy and CO2.
  • Easy integration: The system is pre-assembled, pre-wired, and tested.
  • Fully automatic operation: Intuitive control with the corosys compass. Alternatively, the system can be fully integrated into your process control system.
  • Everywhere in view: With our Smart Machine operational data acquisition, you have access to operational data and reports from anywhere.
