Generate your own nitrogen supply for improved efficiency Extract nitrogen from the air

Nitrogen is a colourless, tasteless and odourless gas ideal for reducing oxidation What is Nitrogen? Nitrogen is an inert, odourless and colourless gas that doesn’t sustain life. It is extremely useful in industry as it prevents fast and slow oxidation. Fires or explosions are perfect examples of fast oxidation. If a vessel is flushed with nitrogen, the oxygen is removed, along with the risk of fire or explosion as these processes need to be fuelled by oxygen. Nitrogen is also used to prevent slow oxidation, i.e. the corrosion of non-organic products or the growth of bacteria in food...

Together with our proven track record and our worldwide presence, having a single point of contact will set your mind at ease, saving costs and allowing you to work more efficiently. On-site nitrogen...

A complete concept for nitrogen generation, that’s our offer! Atlas Copco offers the whole range of machinery for nitrogen generation, from initial compression and filtering right through to the gas’s storage. As a result, with just a simple phone call to your Atlas Copco contact person, any failure in the production process is handled promptly without you having to worry about who to contact. NG (Pressure Swing Adsorption Nitrogen Generator) Compressor Compressor: Atlas Copco’s compressors guarantee a reliable and efficient supply of compressed air to the nitrogen system. Filters Filter:...

Air Vessel: The PSA process, which is inherently a fluctuating procedure, naturally requires a fluctuating inlet flow. To guarantee the smooth operation of the compressed air system, an air vessel is installed before the NG. PSA unit: Atlas Copco’s NG delivers the required nitrogen flow at the required purity with PSA technology. N2-vessel Nitrogen vessel: Since nitrogen production is a discontinuous process, a nitrogen vessel is installed at the outlet of the NG to guarantee a continuous outlet flow of nitrogen.

The right solution for a whole range of applications At Atlas Copco, we know your application and our solutions are a perfect match for your needs. Nitrogen is used in many industries, either in the production process itself or for the handling and storage of goods. This gas can be used either to protect the environment from the product or vice-versa. It is also utilised in applications such as soldering and moulding for increased effectiveness. 1. Blanketing Tank Blanketing refers to applying a cover of nitrogen gas over the surface of a stocked commodity to protect or contain the stored...

2. Modified Atmosphere Packaging (MAP) MAP is an increasingly popular technique used to easily and economically improve product quality and extend shelf-life. Flushing packaged foods with inert high purity nitrogen delays aerobic spoilage and oxidative deterioration by typically reducing the oxygen level in packaged foods to below 1% so that food tastes as good as the day it was made. Nitrogen is primarily used to reduce the oxygen content within food packaging and to avoid product deterioration. A secondary reason for using nitrogen is as a filler gas to provide a pressurised atmosphere...

Two performing technologies to meet your specific demands Whether you need nitrogen of the highest purity or of a lower purity for your specific application, Atlas Copco has the perfect technological solution for you. In the case of membrane air separation, air is pumped through membrane fibres, a process whereby nitrogen is filtered out as it permeates more slowly through the membranes. In the case of Pressure Swing Adsorption, Carbon Molecular Sieves capture oxygen, as a result of which the concentration of nitrogen at the outlet increases (up to 99.9999%). NGM (Membrane Nitrogen...

NG (Pressure Swing Adsorption Nitrogen Generation) The NG unit consists out of two vessels, both of which contain Carbon Molecular Sieves (CMS). While one tower is capturing the oxygen, the other one is regenerating. The CMS is a type of activated carbon with pores in which the oxygen molecules are captured, whereby the output flow has reduced oxygen content. The purity of the nitrogen at the outlet of the NG can be as high as 99.9999%. The Carbon Molecular Sieve has a much narrower range of pore opening than the standard activated carbon which allows the NG to deliver a purity of up to...

A complete and reliable package NGM (Membrane Nitrogen Generation) Application range NGM’s can operate in a much wider range of conditions: The NGM nitrogen generator is supplied as a package containing the inlet air treatment equipment, the regulating valves, the membranes, the nitrogen outlet package and the controls. The range is available for purities of 95% up to 99,5% and Nitrogen flows from 100 Nm³/hr up to 1000 Nm³/hr. This is the standard range and is called NGM. Higher purities and flows can be provided on request. Furthermore, higher customer specs can be met by our NGME units,...
