Vaccum Degassing Plant VWD

Top performance with minimal environmental impactOur water deaeration system VWD combines highest product quality with a resource-saving process. Due to the vacuum, lowest residual oxygen values can be achieved with reduced CO2 requirements.

How does the VWD work?At the top of the column, water is evenly distributed over the structured packing of the water degassing system. Here, the process begins, with the water slowly trickling down through the packing materials - counter to the upward flow of CO2 added at the column sump allowing for efficient oxygen removal.

The special structure of the high-performance packing allows for intensive contact between water and stripping gas, effectively removing oxygen from the water. Operating the column under a vacuum at approximately 80 mbar reduces gas partial pressures, resulting in minimal oxygen levels and CO2 consumption. Nitrogen can also be used as a stripping gas if needed. The degassed water is pumped out from the column sump and can be supplied to a consumer or stored in a buffer tank.Why should you choose the VWD?

  • Lowest oxygen values: corosys guarantees oxygen levels of less than 10 ppb to ensure top product quality.
  • 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, including the vacuum system and CO2 lines.
  • 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.
