LaserGas Generator

A laser gas generator is a dedicated nitrogen generation solution developed to meet the specific demands of laser cutting and related laser‑based manufacturing processes. Oxywise Lasergas Generators are engineered to deliver nitrogen with the purity, pressure stability, and flow characteristics required for clean, precise, and repeatable laser cutting results.

By producing nitrogen directly on site, laser cutting facilities gain greater control over gas quality while reducing their reliance on delivered nitrogen supplies.

Purpose of a Laser Gas Generator

The primary purpose of a laser gas generator is to supply nitrogen optimized for laser cutting operations, where gas performance directly influences cut quality, edge finish, and production efficiency. Unlike general industrial nitrogen systems, laser gas generators are designed to respond quickly to rapid changes in gas demand that occur during laser operation.

Oxywise LaserGas solutions support continuous production environments where nitrogen availability and consistency are critical to machine performance and output quality.

Nitrogen Performance Tailored to Laser Cutting

Laser cutting applications place unique requirements on nitrogen supply, particularly in terms of pressure stability and flow response. A laser gas generator is designed to maintain these parameters under dynamic operating conditions, ensuring consistent protection of the cut area from oxidation.

This tailored performance helps manufacturers achieve clean cuts, smooth edges, and reduced post‑processing, even during high‑speed or high‑power laser operations.

On Site Nitrogen Generation for Production Efficiency

Relying on delivered nitrogen can introduce uncertainty into laser cutting operations through supply delays, pressure variability, or cylinder changes. A laser gas generator eliminates these challenges by producing nitrogen on demand, synchronized with production needs.

This on‑site approach supports uninterrupted operation, improved machine utilization, and greater predictability in daily production planning.

Integration into Laser Cutting Facilities

Oxywise Lasergas generators are designed for straightforward integration into existing laser cutting infrastructure. The system can be connected directly to laser machines or centralized gas distribution networks used within the facility.

This allows manufacturers to upgrade their nitrogen supply strategy without disrupting established production layouts or workflows.

Supporting Cost Control in Laser Operations

Nitrogen consumption in laser cutting can be significant, especially in facilities operating multiple machines or high‑power lasers. By generating nitrogen on site, a laser gas generator helps stabilize operating costs and reduces exposure to market fluctuations associated with bulk or cylinder nitrogen supply.

Over time, this contributes to improved cost transparency and long‑term financial efficiency in laser processing operations.

Nitrogen generators

Nitrogen generators produce nitrogen gas from compressed air and offer a cost-effective, reliable and safe alternative to traditional nitrogen gas supplies such as cylinder or liquid.

Nitrogen generators are available in 8 standard models with capacity in the range from 13 - 90 m3/hour from 95% to 99.9995% purity. Oxywise PSA generators are designed for 24/7 operation. The touchscreen control has user friendly interface with automatic start/stop function based on gas consumption.


PSA Technology

A PSA Nitrogen Generator consists of two columns filled with a carbon molecular sieve (CMS). Pre-treated compressed air enters the active column and flows up through the CMS. Oxygen and other unwanted gases are adsorbed while the nitrogen passes through. The active column then becomes fully pressurized. When this pressure is released, the column becomes inactive and completely regenerates during the depressurization. In order to secure a steady flow of nitrogen each generator is built from two columns; one is active while the other is inactive. At the end of each column’s cycle, they switch roles.
