UHP nitrogen generator NITROBERG®

high-purityfor injection moldingpackaging

Overview
Berg GaseTech NITROBERG® on-site nitrogen generators for gas-assisted injection moulding (GAIM), plastic extrusion and packaging provide continuous high-purity nitrogen at pressures suitable for GAIM (up to 300 bar). Systems are engineered for stable supply, easy integration and predictable operating costs.

Key Performance Indicators

• N₂ purity: 99–99.9% (up to 99.999% at point of use)
• Maximum GAIM pressure: up to 300 bar
• Continuous operation: designed for 24/7 supply
• Customisable flow rates and purity settings

Benefits

• Prevents oxidation and reduces discoloration in plastics
• Improves surface finish and part consistency in high-speed production
• Predictable kWh-based OPEX vs. cylinder/bulk supply
• Lower transport-related emissions and logistics overhead

Features & Technology

• PSA (Pressure Swing Adsorption) with carbon molecular sieves
• Modular configurations: compact units or high-pressure cylinder systems
• Plug-and-play installation and straightforward integration into production lines
• Low-maintenance design with accessible service points and spare parts

Applications in Plastics & Packaging

• Gas-assisted injection moulding (GAIM) at high pressure
• Plastic extrusion to prevent oxidation and enhance surface quality
• Modified atmosphere packaging (MAP) for product preservation
• Any stage requiring continuous, high-purity nitrogen supply

Economic & Sustainability Considerations
On-site generation reduces dependence on external suppliers, eliminates frequent cylinder or bulk deliveries, lowers logistics costs and transport emissions, and typically delivers a favourable ROI within 2–3 years by avoiding recurring purchase costs.

Maintenance & Service
Designed for minimal maintenance with scheduled servicing, easy access to replacement parts and global service support to minimise downtime.

Technological Trends
Improvements in PSA adsorbents and IoT-enabled monitoring are enhancing purity control, reliability and remote system oversight.
