Nitrogen generator–Nitrogen purity: 99.5%

Efficient nitrogen generator providing 99.5% nitrogen purity. Designed for reliable performance in industrial, laboratory, and food packaging applications.

The 99.5% PSA Nitrogen Generator is designed to provide a stable, continuous, and cost-effective nitrogen supply for a wide range of industrial applications. By using Pressure Swing Adsorption (PSA) technology, the system separates nitrogen from compressed air through high-performance carbon molecular sieve (CMS), eliminating the need for traditional nitrogen cylinders or liquid nitrogen delivery.

The generator operates with a dual-tower adsorption system. During operation, compressed air enters one adsorption tower, where oxygen, moisture, and trace gases are selectively adsorbed by the CMS, while nitrogen passes through and is delivered to the outlet. At the same time, the second tower undergoes regeneration. A small portion of the produced nitrogen is used to release the adsorbed oxygen from the saturated CMS, and the exhaust gas is safely discharged into the atmosphere.

A PLC control system automatically switches the two towers every 45–60 seconds, ensuring uninterrupted nitrogen production and stable nitrogen purity at 99.5%. This process provides reliable performance, low energy consumption, fast start-up, and long service life, making it an ideal on-site nitrogen solution for industrial users.

To ensure stable nitrogen purity and efficient long-term operation, the nitrogen generator should be used under the following recommended conditions:

  • Nitrogen purity: 99.5%
  • Inlet pressure: 0.5–0.8 MPa
  • Inlet temperature: ≤ 40°C
  • Nitrogen dew point: ≤ -40°C
  • Ambient temperature: ≤ 40°C
  • Switching cycle: 45–60 seconds
  • Voltage / frequency: 220V / 50Hz
  • Noise level: ≤ 75 dB

For the best performance, the generator should be supplied with clean and stable compressed air. Proper pre-treatment, including air filtration and drying, is recommended to protect the carbon molecular sieve, improve nitrogen generation efficiency, and extend equipment service life.

In the Philippines, where high humidity, warm ambient temperatures, and seasonal heavy rainfall can place greater demands on compressed air pretreatment and gas system stability, the 99.5% PSA Nitrogen Generator is especially suitable for users that require a stable, continuous, and cost-effective on-site nitrogen supply for packaging, inerting, oxidation control, and general industrial protection. With automatic PLC control, fast switching cycles, and reliable PSA separation, the system is well suited for industrial users that want to reduce dependence on nitrogen cylinders or liquid nitrogen while maintaining steady day-to-day production performance.

Recommended applications for the Philippine market include:

  • Food and Beverage Packaging
    Suitable for nitrogen flushing, modified atmosphere packaging, oxidation reduction, and freshness protection in food and beverage packaging lines. This is one of the strongest application directions for the Philippine market because food manufacturing remains a highly relevant local industrial sector.
  • General Manufacturing and Industrial Processing
    Recommended for production lines, protective atmospheres, product handling systems, and general industrial operations that require a continuous and economical nitrogen source. For many routine plant applications, 99.5% nitrogen offers a practical balance between performance and operating cost.
  • Metal Processing and Fabrication
    Applicable to metal fabrication, oxidation reduction, protective atmosphere applications, and related processing environments where on-site nitrogen helps improve process consistency and reduce reliance on delivered gas.
  • Plastics and Injection Molding
    Suitable for molding and plastics production processes where a stable nitrogen supply can support production consistency, gas-assisted operations, and more efficient plant workflow.
  • Electronics Assembly and General Electrical Manufacturing
    Recommended for electronics assembly, oxidation control, and manufacturing support environments where a clean and stable nitrogen source is needed. In the Philippines, electronics-related manufacturing is a particularly relevant direction, but for this 99.5% model the emphasis should be on general electronics assembly and plant support applications, rather than the most purity-sensitive semiconductor process uses.
  • Food Protection and Storage Applications
    Can be used in storage protection, product blanketing, and oxygen reduction applications where nitrogen helps maintain product condition and reduce oxidation exposure during handling or packaging.
  • Chemical Processing and Inert Gas Blanketing
    Suitable for tank blanketing, purging, oxidation prevention, and inert gas protection in chemical and process-related applications where a stable, economical nitrogen source is needed for safer and more controlled operations.
  • Laboratories and Precision Equipment Support
    Applicable to selected laboratory applications, sample handling, general analytical support, and precision equipment that require a stable on-site nitrogen source for routine use. This direction is best presented as general laboratory and equipment support, rather than ultra-high-purity research gas supply.
  • Laser Cutting and Industrial Utility Nitrogen
    Recommended for nitrogen-assisted cutting and other industrial utility uses where users want the convenience of on-site supply and reduced dependence on cylinders, especially for continuous production environments.
  • Factories Seeking Cost-Effective On-Site Nitrogen Supply
    Especially suitable for facilities that want to reduce delivery logistics, improve gas availability, and lower long-term nitrogen supply costs by replacing bottled gas with a stable PSA nitrogen generation system.
  • Coastal and High-Humidity Operating Environments
    For industrial facilities located in coastal Philippine cities or other high-humidity environments, an on-site nitrogen generator can be particularly valuable when paired with proper air filtration and drying, helping maintain nitrogen purity stability and long-term CMS protection under more demanding ambient conditions.
