Nitrogen Generators
The cost-effective, reliable and safe solution for medium to large nitrogen requirements.
CompAir offers an ideal solution with a comprehensive range of cost effective nitrogen generator systems from compressed air, that enable users to produce their total demand for nitrogen gas on their premises and under their control.
Compared to traditional methods of supply, on-site nitrogen generator is exceptionally cost-efficient with a short payback time on investment – in many cases less than twelve months.
Guaranteed performance
- 100% function and performance factory tested
- ASSURE warranty
Rapid return on investment
- Significant cost savings over cylinder or liquid supply provides a typical return on investment of less than 24 months
- Ecomode energy savings control reduces energy consumption during periods of low demand
Fits any application
- Maximum design operating pressure of 16 barg available design quality
- Mass flow controller – ensures correct application pressure and flow
Integral oxygen analyser – continuously measures and guarantees gas quality - Purity guarantee valve – automatically ensures gas meets desired specifications
- Remote monitoring – enables connection to proprietary remote management and generator control systems
Typical Nitrogen Generator Installation
Multi-bank design
Nitrogen generators begin with clean, dry compressed air to create a continuous supply of high purity nitrogen.
The unique multi-bank design (CN2009P to CN2168P) enables additional generators to be added in the future as demand increases and provides redundancy for ease of maintenance. Your CNP Series nitrogen generator can grow with your company. In the diagram above you can see a typical on-site nitrogen gas generation station which uses compressed air.
From left to right in the image above you can see the air compressor (left), air tank to store the compressed air, then dryers & filters to remove water vapour & oil / impurities from the compressed air, then another air tank to store this clean air. The 4 nitrogen generators are shown on the right – they extract the N2 from the compressed air which is stored in the 4 tanks on the right hand side until needed by the process in question.
CompAir Nitrogen Generators – Technical Data
BROCHURE
What is a Nitrogen Generator and how does it work?
The air we breath is approximately 78 percent nitrogen and 21 percent oxygen, a small amounts of other gases, such as neon, and hydrogen make up the other 1%. A nitrogen generator is able to produce a continuous uninterrupted stream of nitrogen gas from clean dry compressed air. It uses a Carbon Molecular Sieve (CMS) bed where oxygen and other trace gases are preferentially adsorbed and the nitrogen is allowed to pass through.
Dual chamber system
Extruded aluminium columns are filled with Carbon Molecular Sieve (CMS). Joined via an upper and lower manifold, the high density filled columns produce a dual bed system. After a pre-set time the control system automatically switches the beds. One bed is always online generating nitrogen while the other is being regenerated. During regeneration, the oxygen that has been collected in the CMS stage and the moisture that has been collected in the optional integrated dryer stage are exhausted to atmosphere. A small portion of the outlet nitrogen gas is expanded into the bed to accelerate the regeneration process.
