Are you struggling to keep your operation cost per laser-cut part low? Does it interrupt production every time you need to change the nitrogen cylinder or refill your tank? Whatever your reason for reviewing your nitrogen supply, we are here to help!
Use of Nitrogen in laser cutting process
Laser cutting is a thermal cutting process with a lot of applications in the world of industrial manufacutring. For the most part they involve processing sheet metal. Laser cutters are capable of engraving metal and quickly cutting sheet metal, even in complex shapes.
Nitrogen is vital as the assist gas to the laser cutting process because of its inertness. Purity of the gas is an important factor in overcoming the tendency for discoloration of laser-cut edges and to provide a high-quality finish. Nitrogen is also critical in:
- Working as a blanket to prevent burning during the applications.
- Establishing a barrier between atmospheric oxygen and the heated metal edge
- Assisting in heat dissipation, so the cut edge will cool faster
Benefits of on-site Nitrogen Generator for laser cutting
If your laser cutting process is a regular consumer of nitrogen, you’re likely (and perhaps even painfully) aware of what a hassle nitrogen-tank rental and delivery can present. The on-site Nitrogen generation system will produce Nitrogen based on your purity requirements and adjust to material thicknesses, up-time, cutting pressures and nozzle sizes.
Increased reliability
Nitrogen generators allow you to produce nitrogen on-demand at any time you need it. By saving the time that is normally spent on waiting for nitrogen deliveries and changing tanks, you can ensure that your application runs continuously and without much attention from the operator.
Less operation cost
Nitrogen assist and purge gas is one of the highest costs associated with laser cutting, particularly for fiber lasers. The capital investment of buying the nitrogen generator is typically returned in a few years, and after that the cost of nitrogen gas is virtually eliminated because there are no recurring charges.
No safety hazard
Generating your own nitrogen on site means no more ordering cylinders, eliminates delivery trucks coming and going from the facility and risk of handling high pressure heavy cylinders while loading and unloading into position.
Avoid gas wastage
on-site generation can produce nitrogen at exactly the needed pressure and flow rate, no gas is bled off in effort to get the gas to these required levels. It avoids with cylinder-rental services, the tanks are often returned with some gas left in them — which can add up to large amounts of wastage over time, especially for businesses that utilize nitrogen in high quantities.
How to choose Nitrogen Generator for laser cutting
Laser cutting requires a reliable supply of high-pressure nitrogen, increasing the nitrogen pressure will result in faster cutting speeds. This speed gain is limited by the cooling effect of high-pressure gas flows. With its energy efficiency, ease of use and small footprint, the Atlas Copco 300-bar Nitrogen Skid is the ideal solution. It is a true plug-and-play solution that delivers cost savings and Nitrogen supply independently for complete peace of mind. All components are built to work together for optimal performance and reliability. With the 300-bar Atlas Copco Nitrogen Skid, you can fill the skid-mounted storage tank or cylinders to create your own supply. This can serve as your nitrogen back-up supply, but also allows you to downsize your system in case of fluctuating demand. Catering to peak requirements with your own pre-filled bottles rather than with a higher capacity generation system offers significant savings.

Leading chemical material company replaces nitrogen bottle with on-site nitrogen generation
Pearl Insulation Materials, a leading chemical material company in UAE equipped with on-site nitrogen generation package instead of purchasing nitrogen in cylinders, which saves time, money and lots of energy.
We no longer wait for nitrogen cylinders to come; the nitrogen is now available 24/7 with the onsite PSA nitrogen generator. Besides, we analyzed the costs compared to purchase of cylinders, we save up to 200,000 AED annually while the payback of investment on the nitrogen generator is 18 months.
