Ultra-low oxygen control for clean, crisp hard seltzers; protect flavour, clarity, and stability with relaible automated deaeration.
In hard seltzer production, dissolved oxygen (DO) is a critical factor in maintaining clean flavour, brightness, and shelf life. Even trace levels of oxygen can cause:
- Off-flavours or aroma degradation.
- Colour shifts and haze formation.
- Microbial instability and shortened shelf life.
- Reduced carbonation consistency and visual appeal.
Many producers still use manual purging or basic gas stripping systems, which can lead to:
- Inconsistent DO levels between batches.
- Excessive COâ‚‚ waste and high operational costs.
- Manual monitoring and adjustments.
- Product variability and risk of oxidation.
To meet commercial beverage standards, producers need a compact, fully automated deaeration system that consistently achieves ultra-low DO levels; without waste, complexity, or downtime.
Our Solution:
- B Automation & 4B Systems delivers Hard Seltzer Deaeration Systems using Alfa Laval’s proven Aldox™ technology; providing reliable, low-maintenance, and energy-efficient oxygen removal.
- Using COâ‚‚ or Nâ‚‚ gas stripping through a hygienic packed column, these systems operate at atmospheric pressure to achieve dissolved oxygen levels below 0.01 ppm (10 ppb). Each unit is factory-built, skid-mounted, and pretested, ensuring rapid installation and consistent operation.
- Full automation, real-time DO monitoring, and recipe management allow flexible operation for different product lines. Integrated diagnostics, remote access, and local technical support from 4B Automation & 4B Systems ensure long-term performance and process reliability.
