Degassing Unit – reliable removal of dissolved gases
Our Degassing Unit efficiently removes dissolved gases such as CO2 and oxygen from purified water and process streams — helping secure stable baselines, improve reproducibility, and protect downstream equipment in pure steam generation, autoclaves and other flow-based applications.
Key benefits
- Effective removal of dissolved gases in purified water (e.g., feedwater to pure steam generators and autoclaves).
- Helps prevent pump cavitation and protects sensitive instrumentation by reducing bubbles and outgassing.
- Chemical-free, inline operation; compact footprint and easy integration into existing skids.
- Supports very low residual O2/CO2 with proper system design using hollow-fiber membrane contactors.
Typical applications
- Pure steam generator feedwater degassing (reduces CO2/O2 to protect steam quality/equipment).
- Autoclave supply water conditioning (stable cycles, fewer baseline drifts).
- RO/EDI polishing loops in pharma water systems (limits ionic load from CO2 and improves EDI performance).
- Boiler feedwater deaeration and general process water corrosion control.
How it works
A hydrophobic hollow-fiber membrane brings liquid and a low-pressure gas phase (vacuum or strip gas)
into contact. The lowered partial pressure on the gas side drives dissolved gases across the membrane,
delivering low residual levels inline without chemical scavengers or tall towers.
