The hydrogen facility is designed to produce approximately 750 tonnes of hydrogen per year, which will be used to fuel public transport vehicles in several Italian towns.

The supplied N2 BOX integrates all components required to produce and store high-purity nitrogen:

• OMEGA AIR VDA 7 screw compressor
• AAF 0076 compressed-air filtration
• RDT 75 refrigeration dryer
• TAC 70 activated carbon tower
• N-GEN 15 PSA nitrogen generator
• 4 kW high-pressure nitrogen booster
• Process cylinder bundle filling at pressures up to 200 bar
• Main electrical box

At the centre of the system is the N-GEN 15 PSA nitrogen generator, producing 4.5 m³/h of nitrogen at 99.999% purity.

Before entering the nitrogen generator, the compressed air is conditioned through several treatment stages. This ensures suitable air quality for reliable PSA operation and consistent nitrogen production.

In hydrogen applications, nitrogen has an important role beyond the production process itself. Because it is inert, nitrogen can be used to displace air and reduce the presence of oxygen in equipment and piping.

At this facility, nitrogen generated will be used for purging and inerting equipment operating in contact with hydrogen.

The system also supports the plant's safety concept by providing a source of high-purity nitrogen for emergency inerting in the event of a process malfunction or hydrogen leak. 

The high-pressure booster and cylinder bundle provide additional nitrogen storage capacity at pressures of up to 200 bar.

By combining compressed-air treatment, PSA nitrogen generation, high-pressure boosting and storage within one container, the N2 BOX provides a compact and integrated source of nitrogen directly at the hydrogen production site.

This project demonstrates how OMEGA AIR technologies can be combined into complete engineered solutions supporting the growing hydrogen industry – from reliable on-site nitrogen generation to applications where purging, inerting and process safety are essential.
