Generating Your Own Nitrogen for Laser Cutting: Pros and Cons

Nitrogen plays a vital role in the laser cutting process, serving both as a purging gas and a cutting assist gas. As a laser user, you have several options for obtaining nitrogen, ranging from purchasing nitrogen cylinders to generating your own nitrogen using a nitrogen generator. In this article, we will explore the pros and cons of generating your own nitrogen for laser cutting, comparing it to bulk nitrogen delivery. We will also discuss the environmental impact and specific considerations when using nitrogen generators for laser cutting. By the end of this article, you will have a comprehensive understanding of the benefits and challenges associated with generating your own nitrogen, empowering you to make an informed decision for your laser cutting needs.

1. Introduction

Nitrogen is an essential component in laser cutting, providing protection to sensitive laser components and preventing metal oxidation during the cutting process. The source of nitrogen for laser cutting can vary, with options including nitrogen cylinders, liquid nitrogen delivery, bulk nitrogen delivery, or generating nitrogen using a nitrogen generator. In this article, we will focus on the pros and cons of generating your own nitrogen through nitrogen generators.

2. The Importance of Nitrogen in Laser Cutting

Before delving into the details of nitrogen generators, it is crucial to understand the significance of nitrogen in laser cutting. In some laser systems, nitrogen is used as a purging gas to ensure the beam path is free from contaminants, safeguarding the delicate components of the laser. Additionally, nitrogen serves as a cutting assist gas, protecting the cut metal from oxidation caused by the high-energy laser beam. The cost-effectiveness of nitrogen makes it a popular choice, as it constitutes 78% of the atmosphere and is readily available.

3. Different Sources of Nitrogen

When considering nitrogen for laser cutting, there are various sources to choose from. These include nitrogen cylinders, liquid nitrogen delivery, bulk nitrogen delivery, or generating your own nitrogen with a nitrogen generator. Each source has its own advantages and disadvantages.

3.1 Nitrogen Cylinders

Nitrogen cylinders, available in packs or interconnected manifolds of cylinders, are a common choice for laser cutting nitrogen supply. While convenient, they may not be the most cost-effective option in the long run.

3.2 Liquid Nitrogen Delivery

Liquid nitrogen can be delivered by bulk gas companies, stored in on-site tanks, and evaporated as needed. While this option ensures a constant supply, it can be costly and involves environmental considerations.

3.3 Bulk Nitrogen Delivery

Bulk nitrogen delivery offers a reliable supply of nitrogen to your facility. However, restrictive contracts and potential price increases can limit flexibility and increase costs over time.

3.4 Nitrogen Generators

Nitrogen generators produce nitrogen on-site, eliminating the need for external supply. They offer a cost-effective solution in the long term, but their efficiency depends on understanding your nitrogen usage pattern to size the generator correctly.

4. Pros and Cons of Nitrogen Generators

Nitrogen generators provide a practical alternative to purchasing nitrogen cylinders or relying on bulk nitrogen delivery. However, like any option, they come with their own set of advantages and disadvantages.

4.1 Pros

• Cost-effectiveness: Generating your own nitrogen is less expensive than purchasing nitrogen, and operating costs are lower in the long run.
• Reduced waste: Nitrogen generators produce nitrogen only when needed, minimizing waste and reducing electricity consumption.
• Flexibility: With a nitrogen generator, you have control over your nitrogen supply, eliminating the restrictions of contracts and external suppliers.
• Environmental impact: Generating nitrogen on-site reduces reliance on truck delivery, resulting in lower carbon emissions and a smaller ecological footprint.

4.2 Cons

• Sizing challenges: Properly sizing a nitrogen generator requires an understanding of your nitrogen usage pattern, which may require a generator larger than your average demand.
• Maintenance considerations: Nitrogen generators may require regular maintenance and occasional repairs, which can add to operational costs.
• Initial investment: Setting up a nitrogen generator system involves an initial investment, although the long-term cost savings often outweigh this expense.
• Technical expertise: Operating a nitrogen generator effectively requires some technical knowledge, which may be a learning curve for customers without prior experience.

5. Bulk Nitrogen Delivery vs. Generating Your Own Nitrogen

When deciding between bulk nitrogen delivery and generating your own nitrogen, several factors come into play. Bulk nitrogen delivery ensures a constant supply, but often involves restrictive contracts and potential price increases. On the other hand, generating your own nitrogen allows for greater flexibility and cost savings, but sizing the generator correctly and acquiring the necessary technical expertise are important considerations. It ultimately depends on your specific needs and priorities.

6. Environmental Impact

The environmental impact of nitrogen supply is a growing concern for many businesses. Generating nitrogen on-site reduces the need for truck delivery, resulting in reduced carbon emissions and environmental impact. Furthermore, generating nitrogen consumes less electricity compared to producing liquid nitrogen, making it a more sustainable option.

7. Generating Nitrogen for Laser Cutting

Generating nitrogen for laser cutting typically involves using nitrogen boosters and compressors to achieve the desired pressure. Historically, oil-free boosters were recommended to prevent oil contamination, but they often came with increased maintenance and unscheduled downtime. However, using lubricated boosters followed by four-stage filtration, as offered by Hull Tech, solves these issues and ensures optimal performance.

8. Nitrogen Boosters and Compressors

Nitrogen boosters and compressors are crucial components in the nitrogen generation process. They help achieve the desired pressure for laser cutting, ensuring efficient and reliable operation. Selecting the appropriate booster and compressor depends on your specific requirements and the nitrogen pressure needed.

9. High-Pressure Nitrogen Storage

High-pressure nitrogen storage, in the form of filling high-pressure cylinder banks, offers additional flexibility when using nitrogen generators. This approach allows for storing extra nitrogen during off-hours for use when needed, based on your cutting hours and nitrogen usage ratio. However, it is essential to consider the trade-off between boosting nitrogen to higher pressures and the associated increase in electricity consumption and operational hours.

10. Requirements for Nitrogen Generators

To obtain a quote for a nitrogen generator, certain information is necessary. This includes the maximum instantaneous nitrogen consumption, consumption history, nitrogen purity requirements, and nitrogen pressure. By providing these details, you can ensure that the nitrogen generator is properly sized and paired with the appropriate nitrogen booster to meet your specific needs.

12. Conclusion

Generating your own nitrogen for laser cutting presents numerous advantages, including cost savings, reduced waste, flexibility, and environmental sustainability. While there are considerations such as sizing challenges, maintenance needs, and initial investment, the long-term benefits often outweigh these factors. By understanding the importance of nitrogen in laser cutting, exploring different nitrogen sources, and delving into the pros and cons of nitrogen generators, you are equipped to make an informed decision for your specific laser cutting requirements.
