CELENO Nitrogen Generator

PSA Technology

Reference | CELENO.[Flow rate]/0 (Without compressor) CELENO.[Flow rate]/1 (With compressor)
GC x GC with Cryogen

With 20 L/min, the CELENO Nitrogen range provides a High Purity Nitrogen solution for GC x GC instrument with Cryogen. The generator has very low dew point to work with cryogenic applications without any freezing.
The CELENO 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


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.
