Beer Production: Deaeration Systems

Protect beer flavour, colour, and aroma; with reliable, energy-efficient oxygen removal systems built for modern breweries.

Dissolved oxygen is one of the most damaging factors in beer production, causing oxidation that dulls hop aroma, affects colour, and shortens shelf life. Many breweries still use outdated deaeration or manual stripping methods that result in:

Inconsistent dissolved oxygen (DO) levels across batches.
Excessive CO₂ or N₂ consumption and operational waste.
Flavour and aroma degradation due to oxygen exposure.
Limited automation or performance tracking.
Increased maintenance and production downtime.

To maintain stable product quality and reduce costs, brewers need an efficient, automated, and hygienic deaeration system that ensures consistently low oxygen levels.

Our Solution:

4B Automation & 4B Systems provides Beer Deaeration Systems engineered for oxygen control and energy efficiency.
Using Alfa Laval’s Aldox™ and Alrox deaeration technologies, these modular, skid-mounted systems remove dissolved oxygen from beer and process water through CO₂ or N₂ gas stripping in packed columns under gentle conditions.
Each unit is fully automated, with real-time oxygen monitoring, recipe control, and remote diagnostics. With 4B Automation & 4B Systems’ integration, commissioning, and local support, breweries gain a consistent, low-oxygen process that reduces gas consumption, improves efficiency, and ensures product quality.
