Claind nitrogen gas generators use PSA (Pressure Swing Adsorption) technology to produce a continuous supply of high purity nitrogen.
High purity nitrogen generators for laboratory application include three models: NG 2081, NG 2301 both available with built in compressor and NG 2300 with external compressor.
The NG 2081 can also be equipped with a catalytic reactor for hydrocarbon removal (NG 2081 HC).
Claind nitrogen generators are unique among competitors. They are featured with the Fastart™ system which allows high purity to be reached after few minutes from start up.
Independence is the main feature of these generators. They only require a supply of mains electricity for automatic, unattended operation. Pressing a button is the only operation to start up the generator, which operates automatically 24 hours a day, 365 days a year.
Maintenance is limited to changing a few filter elements taking less than 30 minutes per year. The system regenerates itself automatically giving you a continuous, uninterrupted supply of gas.
The NG series is microprocessor controlled. The operator can check and set the operating parameters. The maintenance program is embedded in the control system, so the operator is informed at a proper time of the maintenance schedule.
Working Principle:
Thanks to the PSA (Pressure Swing Adsorption) principle the generator produces nitrogen by compressing ambient air and passing it into a Carbon Molecular Sieve bed (CMS).
Inside the CMS bed, oxygen, moisture, CO2 and other 'contaminants' are trapped allowing nitrogen to pass through into a holding reservoir.
Nitrogen from the holding reservoir is regulated to a fixed flow and pressure before exiting the generator.
Available Models:
built in air compressor: NG 2081, NG 2081HC, NG 2301
external air supply: NG 2300
