Nitrogen generation for laser cutting

Are you struggling to keep your cost per laser-cut part low? Does it interrupt production every time you need to change a bottle of nitrogen or refill your tank? Whatever your reason for reviewing your nitrogen supply, we are here to help!

We understand your challenges. After 100 years of operations in the UK we can safely say we've been in business for long enough to understand that you operate in a highly competitive industry where the costs per part are very low!

We supply the complete nitrogen generation package and look after your installation and service from A to Z. Atlas Copco is the only company in the world that designs, manufactures and services the whole nitrogen system including compressors, quality air equipment, nitrogen generators and boosters (up to 40 Barg).  We also have 200 factory trained service engineers who can service your whole system and who are available all over the UK. 

We advise you on your purity and flow requirements.  The extensive testing you've made into the impact and finish of the laser cutting parts has allowed us to help determine the optimum nitrogen purity for any customer's application. We also have plenty of experience in sizing nitrogen packages and utilising high pressure storage for  material thicknesses, up-time, cutting pressures and nozzle sizes.

We offer a state-of-the-art package. Our nitrogen generation system is the market leader in terms of efficiency!  This is due to three main factors:

• It needs the least air for nitrogen ratio. 
• It does not require a desiccant dryer and associated purge air, allowing 20% air saving. 
• It typically offers a minimum of 45% energy savings vs.  competitors (could go up to 75% savings in energy).
• Our NGP+  range provides you with the industry's lowest air factors as standard - as low as 1.8 (95% N2 purity) to 5.4 (99.999%).

• Prevents oxidation: Thanks to its inert properties, nitrogen allows the laser to operate in an oxygen-free environment without the risk of oxidation. When your application heats up and comes in contact with oxygen, a phenomenon known as oxidation occurs. This can cause a carbon layer to form on the cut edge resulting in issues such as poor product finish and adhesion problems for any coating or paint applied to the oxidised surface. 
• Helps purge laser beam: To prevent the beam from distorting and to maintain power and intensity, the beam path needs to be kept clear of dirt particulates and any other contaminants that could cause it to diverge or lose power. Nitrogen is the ideal medium to use for beam guide-way purging as it is dry, clean, oil-free and has a very low contaminant content.

• Lower cost: Nitrogen assist and purge gas are some of the highest costs when it comes to laser cutting, particularly for fibre lasers . So any savings that will be made as a result of generating your own nitrogen will positively affect your bottom line and help you maximise your profit. 
• Higher productivity: By saving the time that is normally spent on changing tanks, you will ensure that your application runs continuously and without much attention from the operator. 
• Better control:  Generating your own nitrogen means no more ordering, changing and running out of bottles. No more liquid deliveries interrupting production, and you no longer have to  deal with suppliers' unpredictable price increases.
• Highest efficiency:  No oxide edge, high purity 99.999% gas available.
• On demand nitrogen: This plug and play solution is sized to match your laser cutter, so you never need to  empty your bottles and  refill during valuable production hours
• Plug and play solution: No need to buy separate compressors and equipment. Easily modified and upgraded if production increases as well as other benefits . 

• A cylinder filling system that is designed to produce a small amount of gas on a continuous basis and then compress it to high pressure (300 – 350 bar g) for storage in a high pressure storage bank(s). This type of system is ideal for intermittent usage or where demand can fluctuate from high to low flow requirements frequently. Typically, a contract laser cutting job shop would benefit from this type of installation.
•  A gas on demand system that is designed to meet the maximum flow requirement of the application with a small buffer stored at 40 bar .
