Overview
BERG provides integrated on-site compressed air, nitrogen and oxygen generation systems tailored for breweries, wineries, bottling plants, coffee producers and beverage manufacturers. Solutions combine industrial compressors, compressed air treatment and PSA nitrogen and oxygen generation into turnkey gas-supply concepts for production, blanketing, purging, filling and process support.

Core solutions

• KOMPBERG — industrial compressed air systems for continuous operation and process air.
• DRYBERG — compressed air treatment including dryers and filters for dry, clean and stable air quality.
• NITROBERG — on-site nitrogen generation for blanketing, inerting, purging, dispensing and packaging.
• OXYBERG — on-site oxygen generation for wort aeration, fermentation support and selected process applications.

Key benefits and value proposition

• German engineering and energy-efficient system concepts adapted to industrial B2B environments.
• Reduced operating costs compared with cylinder or liquid supply by generating gas on site according to demand.
• Improved supply reliability and reduced logistics, rental and delivery dependencies.
• Enhanced product protection through nitrogen blanketing and controlled oxygen supply where required.
• Compressed air treatment ensures hygiene-compliant, dry and clean process air for sensitive beverage applications.

Challenges addressed in beverage production

• Maintaining product quality by minimising oxygen ingress that affects taste, aroma, freshness and shelf life.
• Reducing recurring costs and logistics related to cylinder or liquid gas supply.
• Ensuring reliable gas availability for continuous production and avoiding downtime.
• Meeting hygiene standards with clean, dry gases suitable for beverage processes.

Typical gas flow / process overview

• Step 01 — Ambient air: intake from the production environment.
• Step 02 — KOMPBERG: efficient compressed air generation for the complete system.
• Step 03 — DRYBERG: drying and filtration to stabilise gas generator performance.
• Step 04 — NITROBERG / OXYBERG: on-site nitrogen or oxygen generation to required purity.
• Step 05 — Production use: blanketing, wort aeration, bottling, purging and packaging.

Applications across the beverage industry

• Breweries — wort aeration (O2), nitrogen for purging, keg filling, tank blanketing and dispensing.
• Wineries — nitrogen for displacement of oxygen during storage, transfer and bottling; controlled oxygen for specific winemaking processes.
• Soft drinks and bottling plants — compressed air for pneumatics, filling systems and packaging; nitrogen for blanketing and process control.
• Coffee & nitro coffee — nitrogen for dispensing, packaging and protection of oxygen-sensitive products.

Compressed air system uses

• Process air for pneumatic controls and actuators.
• Filling systems for conveying, filling and container handling.
• Packaging processes including closing, labeling and automation.
• Compressed air treatment to deliver dry, clean and stable supply to process equipment.

Comparison: traditional cylinder supply vs BERG on-site generation

• Operating costs — Traditional cylinder supply: recurring rental, delivery and handling costs. | BERG on-site generation: gas produced on site according to actual production demand.
• Availability — Traditional cylinder supply: dependent on delivery schedules and cylinder stock. | BERG on-site generation: continuous supply when the system is correctly designed and maintained.
• Safety — Traditional cylinder supply: requires handling and storage of high-pressure cylinders. | BERG on-site generation: reduced cylinder handling and simplified site logistics.
• Scalability — Traditional cylinder supply: scaling requires ordering more cylinders or liquid gas. | BERG on-site generation: systems can be planned based on flow rate, purity and future production growth.
• Control — Traditional cylinder supply: less control over supply interruptions and external logistics. | BERG on-site generation: more control over purity, pressure, flow rate and availability.

FAQ highlights

• Nitrogen is used for tank blanketing, inerting, purging, packaging, dispensing and product preservation.
• Oxygen supports wort aeration before fermentation to aid yeast performance and consistent fermentation.
• On-site oxygen generation is feasible and can reduce dependency on delivered oxygen cylinders.
• Nitrogen blanketing replaces oxygen in tank headspace to protect beverages from oxidation.
