Dry nitrogen generator NITROBERG

packagingfor the food industrypackaging machine

Overview
BERG Kompressoren provides complete compressed air systems, compressed air treatment and on-site PSA nitrogen generation for food processing and packaging facilities. Applicable to MAP packaging, meat, dairy, snacks, ready meals and frozen food packaging. Services include turnkey engineering, installation, commissioning and long-term service.

Key trust and quality claims

• Made in Germany
• ISO 9001:2015
• Complete system integration
• Installation & after-sales service

Industry challenges
Food manufacturers require a stable gas supply, hygienic compressed air quality and predictable operating costs. Insufficient air treatment, interruptions in nitrogen supply or oversized systems can affect packaging quality, production uptime and product shelf life.

Typical risks and concerns

• External Nitrogen Dependency — Cylinder and liquid nitrogen deliveries generate logistics, cost and availability risks; on-site generation provides control over supply.
• Compressed Air Quality — Moisture, oil aerosols and particles can compromise equipment reliability and food standards; correct drying and filtration are essential.
• Shelf-Life Requirements (MAP) — Modified Atmosphere Packaging requires consistent nitrogen quality to reduce oxygen exposure and extend shelf life.
• Energy and Operating Costs — Systems must be correctly sized to avoid unnecessary energy consumption, pressure losses and maintenance costs.

How BERG supports food manufacturers
BERG acts as a single point of contact for compressed air and nitrogen infrastructure: assessing demand, defining air quality, sizing nitrogen generators and delivering complete engineered systems.

• Site assessment and demand calculation
• Compressed air, treatment and nitrogen system design
• Turnkey installation and commissioning
• Spare parts, maintenance and long-term service support

Core solutions and product families

• KOMPBERG — Industrial screw compressors selected for air demand, operating profile and efficiency.
• DRYBERG — Refrigerant and adsorption air dryers to achieve required compressed air dryness.
• PUREBERG — Filtration stages to reduce particles, oil aerosols and odours in compressed air for food production.
• NITROBERG — PSA on-site nitrogen generation systems configured by flow rate, purity and operating hours for packaging applications.

On-site nitrogen generation (summary)
BERG configures NITROBERG PSA nitrogen generators according to flow rate, nitrogen purity, operating hours and packaging line requirements. Systems integrate compressor, treatment, generator, installation and service.

Key specification summary
Technology: PSA nitrogen generation
Typical food packaging use: MAP, flushing and blanketing
Feed gas: Compressed air
Project scope: Compressor, treatment, generator, installation and service

Applications in food processing

• MAP packaging
• Meat processing
• Dairy production
• Snack food packaging
• Ready meals
• Frozen food packaging (gaseous nitrogen for packaging, not cryogenic/liquid nitrogen)

Benefits of on-site nitrogen generation

• Lower gas logistics — reduce dependency on deliveries and storage handling
• Continuous supply — generate nitrogen on demand for packaging lines
• Right-sized purity — configure purity to the process instead of overspecifying
• Complete integration — combine compressor, air treatment and nitrogen generator in one engineered system

FAQ (selected)

• What nitrogen purity is needed for food packaging? — Purity depends on product, packaging process and shelf-life target; BERG sizes systems to the real process requirement.
• Can on-site nitrogen generation replace cylinder or liquid supply? — For gaseous nitrogen applications (MAP, flushing, blanketing) PSA generators often replace deliveries; not suitable for cryogenic freezing.
• What compressed air quality is required? — Depends on product contact (direct/indirect/no contact); BERG defines drying, filtration and compressor concept per application.
• Does BERG supply complete systems? — Yes: compressors, air treatment, nitrogen generation, engineering, installation, commissioning and service.
