60Nm³/hr 99.99% Nitrogen Generator with 16bar Outlet Pressure
This PSA nitrogen generator (Pressure Swing Adsorption nitrogen generator) is specialized industrial gas equipment engineered to produce 99.99% high-purity nitrogen at 16bar outlet pressure—specifically designed for stainless steel cutting processes. Using the Pressure Swing Adsorption principle, it extracts nitrogen from ambient air through selective adsorption of oxygen by carbon molecular sieve (CMS), delivering a continuous supply of dry, contamination-free nitrogen. The core advantage of onsite nitrogen generation eliminates logistical constraints of cylinder nitrogen, ensuring consistent pressure and purity for high-precision cutting.
As a high-purity nitrogen generator with high-pressure output, it optimizes stainless steel cutting quality by preventing oxidation, while its energy-saving nitrogen generator design reduces operational costs. This equipment has become indispensable for metal fabrication facilities seeking efficient, cost-effective cutting solutions.

Working Principle of 16bar High-Pressure PSA Nitrogen Generator
The PSA nitrogen generation system operates through a cyclic adsorption-desorption process optimized for high-pressure, high-purity output. Compressed air first undergoes multi-stage filtration (oil, water, dust, and hydrocarbon removal) to meet Class 2.0 (ISO 8573-1) air quality standards—critical for protecting the CMS and ensuring nitrogen dryness. The purified air is then pressurized to 16bar and directed into dual adsorption towers filled with CMS: oxygen molecules are selectively adsorbed by the sieve, while nitrogen molecules (with weak adsorption affinity) pass through as 99.99% high-purity product gas. When one tower reaches adsorption saturation, the system automatically switches to the second tower for continuous supply, while the saturated tower undergoes depressurization and purge regeneration to release adsorbed oxygen. This fully automated process ensures the PSA nitrogen plant working efficiency remains above 96%, delivering stable 60Nm³/hr flow and 16bar pressure for consistent stainless steel cutting performance.
Why 99.99% Purity and 16bar Pressure Matter for Stainless Steel Cutting
Stainless steel (e.g., 304, 316L) contains chromium and nickel, which are highly prone to oxidation at high temperatures (above 800℃) generated during cutting. Here's why the generator's key specifications are essential:
- 99.99% Purity: Even 0.01% oxygen in nitrogen can cause visible oxide scale on cut edges, compromising corrosion resistance and aesthetic appeal. For applications requiring food-grade or medical-grade stainless steel, 99.99% purity is a minimum standard to meet industry regulations.
- 16bar Pressure: Lower pressure (≤10bar) fails to effectively displace oxygen in the cutting kerf, especially for thick plates. 16bar ensures nitrogen flows evenly across the cut surface, maintaining the inert atmosphere and cooling the workpiece to prevent warping. For high-speed laser cutting, 16bar pressure also helps remove molten metal debris, improving cut precision.
Maintenance & Care for Cutting-Specific PSA Nitrogen Generator
To ensure consistent performance in stainless steel cutting environments (often dusty, high-temperature), follow these maintenance guidelines:
- Filter Replacement: Replace pre-filter elements every 2-3 months (more frequently for dusty workshops) to prevent CMS contamination. Replace the activated carbon filter every 12 months to remove hydrocarbons.
- CMS Maintenance: Monitor nitrogen purity and pressure drop monthly. Replace the CMS every 5-6 years (or if purity drops below 99.98%) to maintain adsorption efficiency.
- High-Pressure Component Inspection: Check high-pressure pipelines, valves, and seals quarterly for leaks. Tighten connections and replace worn seals promptly to avoid pressure loss.
- Control System Calibration: Calibrate the PLC, pressure sensors, and purity analyzer annually to ensure accurate monitoring and control—critical for maintaining 16bar pressure and 99.99% purity.
- Drying System Maintenance: Drain the air dryer's condensate daily. Replace the dryer's desiccant every 2 years to ensure nitrogen dryness (dew point ≤-40℃).
Factors to Consider When Choosing a PSA Nitrogen Generator
Selecting the right PSA nitrogen generator for stainless steel cutting requires evaluating these key factors:
- Purity & Pressure Matching: Ensure the generator delivers 99.99% purity and 16bar pressure (or adjustable to your cutting machine's requirements). Avoid over-purchasing higher purity (e.g., 99.999%) unless required by specific applications.
- Capacity Alignment: 60Nm³/hr is suitable for medium-scale workshops (1-2 cutting machines). For large-scale operations, opt for modular nitrogen generator designs to expand capacity (e.g., combining two 60Nm³/hr units for 120Nm³/hr).
- Energy Efficiency: Prioritize energy-saving nitrogen generator models with power consumption ≤0.7kW/Nm³ to reduce long-term operational costs.
- Durability: Choose a generator with corrosion-resistant materials (e.g., stainless steel casings) to withstand the dusty, high-humidity environment of metal fabrication workshops.
- After-Sales Support: Select a reputable PSA nitrogen plant manufacturer with experience in metal cutting applications. Ensure access to on-site installation, training, and timely spare parts supply.
