With 3 models, 1 l/min to 5 l/min, the Z.NESO Nitrogen range provide a High Purity Nitrogen solution for GC/ICP/TOC instrument.
For the Z.NESO, a heated catalyst oxidises CH4 from the Nitrogen gas flow providing Zero Nitrogen with Total hydrocarbon less than 0.05 ppm. 
The Z.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. 
Advantages product
INCREASED LABORATORY EFFICIENCY
A constant, uninterrupted gas supply of guaranteed purity eliminates interruptions of analyses to change cylinders and reduces the amount of instrument re-calibrations required.
IMPROVED ECONOMY
Pure nitrogen gas produced as standard.
IMPROVED SAFETY
Nitrogen produced at low pressure and ambient temperature removes the need for high pressure cylinders.
SECURITY OF SUPPLY
Integral oil free air compressor as an option guarantees continuous gas supply, independent of in house compressed air supply.
SIMPLE INSTALLATION
Gas generators can be installed in the laboratory, on or under a bench, eliminating the need for long gas lines from cylinders secured elsewhere.
