With 3 models, 1 L/min to 5 L/min, the NESO Nitrogen range provide a High Purity Nitrogen solution for GC/ICP/TOC instrument.

The NESO is available without or with integrated oil free air compressor using the Energy Saving Technology mode (EST). It is extremely compact and quiet in operation.

The generator is controlled using the latest in color touch screen technology to display the process in real time, inlet / outlet pressure, N2 Flow and status of the system with remote access for diagnostic control.

Utilizing Advanced technology PSA of separating Nitrogen and Oxygen to produce high quality Nitrogen gas on demand 24/7.

A constant, uninterrupted gas supply of guaranteed purity eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.

Pure nitrogen gas produced as standard.

Nitrogen produced at low pressure and ambient temperature removes the need for high pressure cylinders.

Integral oil free air compressor as an option guarantees continuous gas supply, independent of in house compressed air supply.

Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere.
