Nitrogen Generator for Laser Cutting


How Is Nitrogen Used in Laser Cutting?

If you’ve ever had your laser cutting operation put on hold due to running out of nitrogen or waiting for the tanks to refill, on-site nitrogen generation might be a good fit. Nitrogen plays a crucial part in many laser-cutting applications, and a nitrogen generator can create it on demand, so you’re always ready for the next job.

Liberty Systems manufactures nitrogen generators and high-performance air systems for cutting assist gas. Our systems are based on either membrane or pressure swing adsorption (PSA) air separation technology, and we can help you determine which is best for your application.

Laser cutting comes in many different forms, but the basic idea involves a high-powered laser that can cut through metals. These industrial cutting machines can produce everything from intricate components for equipment to structural materials used in construction.

Nitrogen often serves as an assist gas, which blows away melted material to refine the cut edge and improve process efficiency. Some assist gases, like oxygen, generate additional heat, which affects the material’s edge. They can also create an oxide layer on the material, creating a different appearance and affecting finishing demands.

Nitrogen, being inert, does neither. It can push melted metal away from the cut without otherwise affecting the melting process or the surface finish. Another application of nitrogen for laser cutting is purging the cutting head. Keeping the laser’s path clear of contaminants helps it maintain its path and power.

Nitrogen Generators for Laser Cutting Machines

Nitrogen laser cutting usually requires working with a supplier or generating nitrogen yourself. Suppliers can be expensive and unreliable, but our leading nitrogen generators allow you to create this gas on-site at a lower cost. We offer sophisticated PSA generators for high purity levels of up to 99.999%, while our powerful membrane systems offer up to 99.9% purity. Both types of generators work alongside an air compressor to separate oxygen and nitrogen molecules before sending the nitrogen toward the outlet.

Generators from Liberty Systems are built to last. We make bulletproof equipment with 99.9%+ uptime, all supported by our attentive, knowledgeable team. ISO 9001 quality standards go into each of our units, and we back them with an exceptional three-year warranty. With dependability front and center, our nitrogen generators can minimize downtime and reduce costs for your laser-cutting operation.

The Benefits of Using Generated Nitrogen for Laser Cutting

Nitrogen is an excellent assist gas for laser cutting. It can help improve the efficiency of the cutting process and provide cleaner edges, allowing laser cutters to improve both speed and quality. Using an on-site nitrogen generator for laser cutting machines offers exceptional benefits, such as:

  • Reducing costs: Creating your own nitrogen can be significantly cheaper than buying it from a supplier. It can also eliminate many of the logistical challenges, like renting and managing tanks and arranging deliveries. These labor-intensive activities contribute to the cost of purchased nitrogen.
  • Better uptime: Interruptions to your nitrogen supply, such as a delayed delivery or a spike in usage, can bring operations to a halt. With on-demand generation, you can keep things moving and eliminate downtime.
  • Improved control: Generating your own nitrogen gives you complete control over your supply. You can determine when it’s created, how pure it is and how it gets delivered to your laser cutter. Plus, you no longer need to deal with supplier relationships and unpredictability.

The Liberty Systems Difference

We have assembled a group of sales engineers who specialize in gas quality for all things related to lasers. Anyone can punch numbers into an app and hope for the best. We will work with you to discuss your current requirements and plans for the future. We can build redundancy into your system to maintain uptime. If you already have a source of compressed air in your facility, let us know, and we may be able to incorporate it into the system.

In addition to nitrogen and high-performance air systems, Liberty also offers two types of gas mixers that can be used for assist gas. ​Installation of a nitrogen generation system can help eliminate or reduce your monthly liquid nitrogen, delivery, trifecta and tank rental expenses. In addition, it eliminates the burden of a gas supplier agreement. We make some of the most reliable on-site nitrogen generators on the market, and our attentive team is there to support you every step of the way, from sales to ongoing maintenance services.
