What Is a Nitrogen Generator?

A nitrogen generation system is a device that extracts nitrogen from the air and delivers it in a pure, usable form. Unlike traditional nitrogen tanks, a nitrogen gas generator produces an uninterrupted supply of nitrogen on demand, eliminating the need for frequent refills or deliveries.

In the beverage industry, nitrogen is widely used for nitro coffee, draft beer, and wine dispensing, ensuring a smooth, creamy pour with optimal freshness. Businesses that rely on nitrogen tanks may find that switching to a liquid nitrogen generator or an on-site nitrogen generator system provides cost savings, efficiency, and convenience.

Why Do You Need a Nitrogen Generator?

• Cost Savings: Over time, the nitrogen generator price is offset by eliminating recurring refills and delivery fees.


• Continuous Supply: Never worry about running out of nitrogen during peak hours.


• Improved Beverage Quality: A consistent supply of nitrogen enhances the texture and taste of nitro-infused drinks.


• Environmental Benefits: Reduce waste and carbon footprint compared to traditional nitrogen tank deliveries.


• Space Efficiency: No need to store bulky tanks-integrated nitrogen generators fit seamlessly into beverage operations.

Nitrogen Generator vs. Nitrogen Tank: What's the Difference?

How to Compare Nitrogen Generators

When shopping for a nitrogen gas generator, consider these key performance and cost factors to ensure the best fit for your beverage system:

Nitrogen Purity Levels

For beverage applications-especially nitro cold brew coffee, beer, and wine dispensing look for generators that deliver at least 99.5% to 99.9% nitrogen purity.

• 99.9% purity is ideal and prevents oxidation or unwanted carbonation.
• Purity below 95% may not be sufficient for long-term freshness or product quality.

Flow Rate (SCFH or L/min)

Flow rate determines how much nitrogen a generator produces per hour, usually measured in Standard Cubic Feet per Hour (SCFH) or Liters per Minute (L/min).

• Low-volume operations: 5-10 SCFH or 2-5 L/min
• Medium-volume bars or cafés: 10-20 SCFH or 5-10 L/min
• High-volume venues: 30+ SCFH or 15+ L/min

Pressure Output (PSI/Bar)

Pressure capacity is essential for effective dispensing.

• Most beverage systems require a pressure range of 20-60 PSI (1.4-4.1 Bar).
• Some systems may need up to 100 PSI (6.9 Bar).

Energy Consumption (kWh)

Nitrogen generators can consume between 0.2 to 1.5 kWh depending on size and efficiency.

• High-efficiency units: <0.5 kWh per SCFH
• Avoid models >1.0 kWh unless necessary for very high output

Maintenance Needs

Routine upkeep is key to longevity and performance.

• Most systems require filter changes every 6-12 months
• Some premium models include auto-monitoring or long-life filters

Nitrogen Generator Cost

• Small generators: $1,500-$2,500
• Medium-output models: $3,000-$5,000
• High-output commercial units: $6,000+
• ROI: Many recoup the cost within 1-2 years vs. tank refills

Safety Measures for Nitrogen Generators

• Ensure Proper Ventilation: Nitrogen displaces oxygen, so generators should be used in well-ventilated areas.


• Monitor Gas Levels: Install oxygen sensors in enclosed spaces to prevent potential asphyxiation risks.


• Regular Maintenance: Keep filters and compressors clean to ensure efficient operation.


• Train Staff: Educate employees on proper handling and safety precautions.
