Deliver ultra-low oxygen brewing water for consistent quality, flavour stability, and shelf life; with hygienic, efficient Alfa Laval technology.
Low concentration of dissolved oxygen in brewing water can cause oxidation, colour change, and off-flavours that damage beer stability and taste. Many craft breweries still rely on manual purging or open-tank deaeration, which often proves:
- Inconsistent; leading to variable oxygen levels between batches.
- Inefficient; wasting COâ‚‚ or nitrogen gas and energy.
- Difficult to monitor; with no reliable DO control or feedback.
- Labour-intensive; requiring frequent manual adjustment.
To ensure stable, oxygen-free brewing, a dedicated, automated deaeration module is essential; combining hygiene, energy efficiency, and repeatable results.
Our Solution:
- 4B Automation & 4B Systems offers Craft-Scale Deaeration Systems engineered to deliver water with dissolved oxygen levels typically below 0.01 ppm.
- Using Alfa Laval’s proven Aldox™ deaeration technology, these compact, skid-mounted systems use CO₂ or N₂ gas stripping through a hygienic packed column to achieve consistent, ultra-low oxygen levels.
- Each module is plug-and-play, fully automated, and CIP-ready; integrating easily into existing brewery utilities. Real-time monitoring, user-configurable DO setpoints, and remote diagnostics ensure optimal control and minimal gas consumption.
- With installation, service, and support from 4B Automation & 4B Systems, you gain a dependable, low-maintenance solution built to protect flavour integrity and improve operational consistency.
