NITROGEN with PSA Technology :

Nitrogen Generator -  PSA technology

(including Nitrogen/Air Generator)

HIGH FLOW

SMALL FLOW

DS-PSA TECHNOLOGIE

 BENEFITS AND SAVING :

• Better results from analytical instruments
  The constant purity of the nitrogen improves system stability and ensures reproducible results

• Better lab efficiency

• Improved safety

• simple installation

• Recommanded by analytical instrumentation manufacturer

APPLICATION

Nitrogen produced at low pressure from a source of compressed air and at room temperature eliminates the risks relating to high pressure gas bottle use and
the handling of liquid nitrogen for these applications :

• GC-Carrier Gas

• GC-FID, NPD, ECD, AED

• ICP

• ELSD

• TOC

• LCMS

• Supply a complete laboratory to feed several analytical instruments (LCMS, ICP, Solvent Evaporation)

OPERATING MODE

The Nitrogen generator use pressure swing adsorption technology (PSA) to produce pure nitrogen gas.
This technique uses a bed of carbon molecular sieve (CMS) to selectively remove oxygen and other contaminants from atmospheric air. The bed alternates between purification and regeneration modes to ensure continuous nitrogen production.
The gas generator is designed to take compressed air at 7 barg from an integral oil free air compressor which is firstly pre filtered. This filtered compressed air stream is then passed to the CMS bed currently in purification mode. Whist passing through the bed, the oxygen, carbon dioxide, moisture and some hydrocarbons are removed from the compressed air, resulting in a product stream of clean, dry, high purity nitrogen gas.

§         Flow rate : 500cc/min to 40l/min

§         Nitrogen purity : from 98% to 99,9995%

§         Pressure : 5 bar or 7 bar

§         Option: Integral oil free air compressor

Allows to be franked from any network. This range of generator has an acceptable sound level within a laboratory (< 55 dB).

§         Easy and quick maintenance :

 Equipped with filters of high efficiency, limiting considerably the maintenance, some minutes only to change internal filters and silencer.

§         Modular :

Their modularity allows to obtain several gases with a single module as the combined nitrogen / air: ideal for the GC (Nitrogen for carrier gas or make up and Air for the FID)

* OTHER OPTIONS:
-Oxygen analyser
-Catalyst module for hydrocarbons level< 0.05ppm

* Auto start

* Alarm display with help menu

* Audible alarm sounder

* Outlet flow indicator

* Trend graphs for QA reporting

* Compressor over temperature alarm

* Remote acess to screen using internet or GSM

* Energy saving Mode
The generator has a real-time calendar and clock which can be easily updated no matter where you are in the World. By using the Auto-Run function you can select when the generator runs giving you complete control of your gas supply and saving energy.
Example: If your laboratory working hours is 8am to 6pm, set the generator to start at 5am to ensure you have high quality gas at 8am and have it switch off at 7pm, reducing running time and energy by some 55%.

Why to choose F-DBS ?

• F-DBS nitrogen generators offer you an innovative and unique solution for the supply of nitrogen on-site.

• A nitrogen source sure and reliable can be produced from your clean and dry compressed air network eliminating the need of high-pressure gas cylinders or liquid nitrogen.

Range available:

•  MAXIMUS LITE

•  MAXIMUS

Depending on purity and flow require by your application, we recommend MAXIMUS LITE or MAXIMUS range

Conceived for a continuous operation, the MAXIMUS LITE and MAXIMUS nitrogen generator can produce flow rates from a few liters per minutes to over NL/min at purities in oxygen content residual from 10 ppm to 3%.

The generator is controlled using the latest in HMI touch screen technology to display the process, pressures, inlet air dewpoint and oxygen levels with continuous
monitoring complete with alarms.

Others Applications: food packaging, laser cutting, wine making and brewing, oil and gas, pharmaceutical and laboratory, electronic assembly/soldering, injection moulding
