UHP nitrogen generator

ultra high-purityhigh-purityindustrial

Product description
Industrial sites that use cylinder or bulk nitrogen incur ongoing logistics costs and risk supply interruptions. On-site nitrogen generators produce gas from compressed air on location, helping reduce operating costs, remove supplier dependence and stabilize production processes.

Applications

• Food industry (modified atmosphere packaging)
• Laser cutting and metal processing
• Electronics and precision manufacturing
• Refrigeration and HVAC systems
• Medical facilities and laboratories

Installation options
Units can be installed inside production halls or supplied as complete containerized stations.

Economic advantages

• eliminates cylinder and cryogenic tank deliveries
• ensures continuous availability of nitrogen
• reduces losses during system changeovers
• allows control of gas production cost
• increases operational independence

How the nitrogen generator works (PSA + CMS)
Generators use PSA (pressure swing adsorption) and carbon molecular sieves (CMS). Step-by-step process:

• compressed air is fed into adsorption columns
• CMS adsorbs oxygen and other gases
• nitrogen passes through as the product gas
• the second column regenerates at the same time

The alternating operation of columns provides continuous nitrogen production. The system also includes air filtration, a buffer tank and automation to control operating parameters.

Typical performance

• nitrogen purity: from 95% to 99.999%
• working pressure: typically 4–10 bar
• capacity: from small units to large industrial systems (sized to the application)

Problem solved
Cylinder or bulk nitrogen deliveries create logistical constraints and costs. On-site generation provides nitrogen on demand, stabilizes production processes, simplifies gas logistics and reduces total cost of ownership.

How to select a generator
Selection depends on:

• required nitrogen purity
• flow rate (gas consumption)
• operating pressure
• operating mode (continuous / intermittent)
