Hot Degassing System HWD

Efficient water degassing with integrated pasteurizationWith our hot water degassing system (HWD), the water is additionally pasteurized during the degassing process. This ensures both excellent residual oxygen values and a high level of microbiological safety. Furthermore, the robust hot degassing process consumes less CO2.

How does the HWD work?The incoming water is first preheated in a heat exchanger by coming into contact with already degassed hot water. It is then brought to the desired degassing temperature using steam or hot water and evenly distributed over the structured packing at the column head. Here, the process begins where the water slowly flows down through the packing while CO2 is introduced in countercurrent from below.

The special structure of the packing allows for efficient contact between water and stripping gas to optimally remove oxygen. The increased temperature helps reduce the solubility of oxygen,  supporting the efficient removal of oxygen from the water.. Nitrogen can also be used as stripping gas if needed. The degassed water is pumped out of the column sump, cooled through a heat exchanger, and can then be supplied to a consumer or stored in a buffer tank.

Why should you choose the HWD?

  • Best oxygen values: With oxygen values of less than 10 ppb, we ensure outstanding product quality.
  • High heat recovery: Regenerative heating allows for the recovery of up to 96% of heat, saving both heating and cooling energy.
  • Low CO2 consumption: Our system consumes less than 0.4 g/l CO2, saving costs and minimizing environmental impact.
  • Complete clean concept: Our system is designed for comprehensive and effective cleaning.
  • Energy efficiency: Thanks to the FLOW ADAPT algorithm, degassing performance adapts to the buffer tank‘s fill level, saving energy.
  • Easy integration: The system is pre-assembled, pre-wired, and tested.
  • Fully automatic operation: Intuitive control with the corosys compass allows for effortless operation, or 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.
