Dry nitrogen generator NITROBERG®500

ultra high-purityhigh-purityUHP

Overview
Pre-engineered, skid-mounted NITROBERG® PSA nitrogen generation packages for on-site nitrogen supply. Each skid combines PSA generator, compressed-air treatment, buffer vessels, instrumentation and electrical integration on a coordinated metal frame for fast installation and commissioning.

Package summary

• NITROBERG® PSA nitrogen generator (model dependent)
• Compressed-air treatment: high-efficiency filters, water separator and refrigeration or adsorption dryer options
• Air receiver(s) and nitrogen buffer vessel(s) with condensate drains and accessories
• Nitrogen purity and pressure sensors
• Pre-installed piping, valves and electrical wiring on a common skid
• Siemens PLC and HMI process control (or equivalent)
• Optional integrated air compressor or connection configuration for existing compressed-air supply
• Base-frame layout and operation documentation included

Typical documentation included

• Assembly/layout drawing
• Piping & Instrumentation (P&ID/R&I) diagram
• Plant description and functional drawings
• Electrical wiring and terminal block diagrams
• Operation & Maintenance manual and spare parts list

How it works (process)

• Compressed-air preparation: Ambient air is compressed, dried and filtered to protect the molecular sieve.
• PSA nitrogen generation: Oxygen is selectively adsorbed while nitrogen passes to the product line.
• Buffer storage: Produced nitrogen is stored to stabilise flow, pressure and handle demand peaks.
• Controlled supply: Continuous monitoring ensures purity and controls product-gas delivery with off-spec protection.

Key features

• Standard purity range: 97% – 99.999% N2 (model dependent)
• Siemens PLC/HMI process control and continuous purity/pressure monitoring
• Matched dryer and filtration to protect adsorbent
• Correctly sized air and nitrogen receivers
• Pre-installed piping and electrical wiring for rapid installation
• Automatic operation with off-spec gas protection and alarm options

Additional options and capabilities

• Integrated screw air compressor (optional)
• Demand-led control, standby operation and redundancy
• Remote monitoring and alarm integration
• Skid or containerised integration
• Commissioning, site testing and technical support

Industrial applications

• Food and beverage: MAP, tank blanketing, bottling and purge operations
• Electronics and semiconductors: inert atmospheres for soldering and assembly
• Chemical and pharmaceutical: purging, blanketing and process protection
• Oil & gas: on-site purging, maintenance inerting and pressure testing
• Laboratories (LC/MS): supply for detectors and curtain gas
• Metal processing and heat treatment: inerting and process support

Project-specific configuration
The skid must be sized to required nitrogen flow (Nm3/h), purity, outlet pressure and compressed-air demand; receiver volumes and redundancy are project-dependent. Excessive purity requirements reduce output and increase energy consumption.

Data required for an engineered proposal

• Required nitrogen flow (Nm3/h)
• Required nitrogen purity or residual oxygen level
• Required outlet pressure and any pressure peaks
• Daily operating hours and load profile
• Installation country, altitude and ambient temperature
• Application, applicable standards, redundancy and backup requirements

Certifications, standards and compliance
Equipment and workmanship comply with applicable codes and standards (e.g. DIN, VDI/VDE, IEC); other standards (ASME, ATEX, GL, BV) can be applied by agreement.
