A leading craft brewery in Salford has recently upgraded its production utilities with our fully integrated compressed air and on-site nitrogen generation system, achieving significant improvements in product consistency, production efficiency, and operational cost control. The installation demonstrates the growing shift in the brewing industry toward in-house nitrogen generation as a more sustainable and cost-effective alternative to bottled or liquid nitrogen delivery.
Client Background
Established in 2008, the brewery is known for producing premium cask ales, lagers, stouts, and custom-brewed specialty beers. After expanding to a larger production facility, the brewery sought to streamline its processes through modern, energy-efficient utilities capable of supporting higher output volumes while maintaining strict beer quality standards.
Throughout the brewing process, a stable supply of high-purity nitrogen and clean compressed air is essential for:
- Purging tanks, kegs, and casks
- Wort aeration and fermentation control
- CIP and sanitization procedures
- Packaging, bottling, labelling, and final filling
- Preventing oxidation and preserving flavour stability
Challenges Before the Upgrade
The brewery’s previous rented nitrogen equipment was no longer capable of meeting increased production demand, nor could it reliably support future growth. Rising nitrogen delivery costs, inconsistent purity, and operational downtime prompted the brewery to seek a self-sufficient, high-purity nitrogen generation system.
Key client objectives:
- A stable, continuous nitrogen supply
- Lower operating costs and reduced reliance on deliveries
- Improved purity control and system automation
- Energy-efficient compressed air to support beer production and nitrogen generation
- A rapid return on investment
Our Delivered Solution
We supplied a complete, plug-and-play compressed air and PSA nitrogen generation package engineered specifically for food and beverage applications.
1. High-Efficiency Rotary Screw Air Compressor
- Continuous, stable air supply at 10 bar
- Integrated drying system for moisture-free air
- Compact tank-mounted design
- Ideal for aeration, keg purging, filling lines, and nitrogen feed air
2. Multi-Stage Air Filtration System
To ensure ISO-standard air quality suitable for on-site nitrogen production, the system includes:
- Coalescing filtration
- Particulate removal
- Activated carbon filtration for odour and hydrocarbon elimination
This guarantees clean, dry air — essential for long-term PSA nitrogen generator performance.
3. PSA Nitrogen Generator (Up to 99.999% Purity)
Our PSA nitrogen generator uses carbon molecular sieves to separate nitrogen from compressed air, producing nitrogen at controlled purities from 95% to 99.999%.
Key features:
- Fully automatic operation
- Real-time oxygen monitoring
- “Off-spec protection” to ensure only high-purity nitrogen enters production
- Low operating cost compared with liquid or cylinder nitrogen
- Buffer tank design for stable pressure and continuous supply
The system provides nitrogen for keg and tank purging, stout nitrogenation, carbonation support, and oxidation prevention throughout packaging.
Results and Performance Benefits
The upgraded nitrogen and compressed air setup has helped the brewery optimise brewing operations and achieve consistent beer quality across multiple styles.
Key benefits delivered:
✔ Continuous, uninterrupted nitrogen supply
✔ Lower operating costs compared to bottled/liquid nitrogen
✔ Improved purity control and process safety
✔ Enhanced carbonation and nitrogenation consistency in specialty beers
✔ More stable fermentation thanks to controlled wort aeration
✔ Reduced environmental impact and carbon emissions
✔ No more delivery logistics, rental fees, or cylinder handling
The new utilities also supported the client’s development of a nitrogen-infused keg stout with the signature cascading pour — a product previously difficult to stabilise using delivered nitrogen sources.
Why More Breweries Choose On-Site Nitrogen Generation
Breweries worldwide are switching to on-site nitrogen due to:
- Rising transport and delivery fees
- Liquid nitrogen boil-off losses
- Cylinder shortages and inconsistent supply
- Hazmat storage requirements
- High long-term cost per Nm³
Our PSA nitrogen systems allow breweries to:
- Produce nitrogen on-demand
- Control purity based on application needs
- Improve sustainability
- Reduce oxygen exposure
- Increase efficiency across the entire production line
Conclusion
The success of this project highlights how our integrated compressed air and nitrogen generation solution enables breweries to improve product quality, reduce operating costs, and ensure a reliable supply of high-purity nitrogen for every stage of production.
Whether for craft breweries, beverage manufacturers, or large-scale food producers, on-site nitrogen generation is now one of the most cost-efficient and dependable utilities available.
