Compared to our Modular PSA Nitrogen Generators, the NITROPLUS® Twin-Tower PSA Nitrogen Generators from NOXERIOR are designed for tonnage nitrogen consumptions.

These Twin-Tower systems are designed for heavy-duty operation, where system availability in combination with low running costs are primary objectives.

The key features of the NITROSWING® Twin-Tower PSA Nitrogen Generators are::

High Reliability
Low gas speeds through the molecular sieve beds, first-class components, stainless steel valve bodies and instrument air tubing, heavy-duty industrial PLC. It should work. Always.

Lowest Energy Consumption
Optimised PSA tower design and process piping in order to minimize dead volumes for lowest feed air consumption. Let NITROSWING® really make you save money.

Easy Integration
All system tie-in points on one side in order to facilitate the installation of the plant and the integration with your existing equipment.

Heavy-duty adsorption towers, designed and certified for an unlimited number of cyclic loads.

An extended list of options allow you to define your specific NITROSWING® Twin-Tower PSA Nitrogen Generator adjusted to your individual need;
