Nitrogen generator–Nitrogen purity: 99.99%

Nitrogen generator with 99.99% purity—reliable, efficient, and built for demanding industrial applications.

The PSA Nitrogen Generator uses Pressure Swing Adsorption (PSA) technology to separate nitrogen from compressed air and provide a stable, on-site nitrogen supply with purity up to 99.99%. It is designed for users who need continuous nitrogen production without depending on gas cylinders or liquid nitrogen.

The system operates with a dual-tower structure filled with high-performance carbon molecular sieve (CMS). When compressed air enters one tower, oxygen is selectively adsorbed by the CMS, while nitrogen passes through and is delivered to the application point. At the same time, the other tower is regenerated by releasing the adsorbed oxygen into the atmosphere.

Once the first tower reaches saturation, the system automatically switches to the second tower for adsorption, while the first tower begins regeneration. This alternating cycle ensures continuous nitrogen production, stable purity, and reliable long-term operation. With PLC automatic control and optimized switching cycles, the generator offers efficient nitrogen separation and reduced compressed air consumption.

To ensure stable nitrogen purity and reliable system performance, the PSA nitrogen generator should operate under the following recommended conditions:

  • Nitrogen purity: up to 99.99%
  • Inlet pressure: 0.5 – 0.8 MPa
  • Inlet temperature: ≤ 40℃
  • Nitrogen dew point: ≤ -40℃
  • Switching cycle: 45 – 60 seconds
  • Ambient temperature: ≤ 40℃
  • Voltage / frequency: 220V / 50Hz
  • Noise level: ≤ 75 dB

For the best operating result, the generator should be supplied with clean and stable compressed air. Proper pre-treatment, including filtration and air drying, is recommended to protect the carbon molecular sieve, maintain nitrogen purity, 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 PSA Nitrogen Generator is especially suitable for users that require a continuous, on-site nitrogen supply without relying on cylinders or liquid nitrogen. With nitrogen purity up to 99.99%, automatic PLC control, and a stable dual-tower PSA process, the system is well suited for industrial users that need reliable nitrogen generation for packaging, inerting, purging, testing, and moisture-sensitive production environments.

Recommended applications for the Philippine market include:

  • Food and Beverage Packaging
    Suitable for nitrogen flushing, modified atmosphere packaging, product preservation, and oxidation control in food and beverage packaging lines. In the Philippines, food manufacturing remains an important industrial sector, making this one of the strongest localized application directions for an on-site nitrogen generator.
  • Electronics and Electrical Manufacturing
    Recommended for soldering support, reflow-related processes, electronics assembly, dry process support, and moisture-sensitive production environments. Electronics remain the country’s top export category, so this is one of the most relevant application directions for the Philippine market.
  • Pharmaceutical Production and Clean Packaging
    Applicable to pharmaceutical production support, packaging, storage protection, and controlled manufacturing environments where a stable on-site nitrogen supply helps support product quality and process consistency.
  • Chemical Processing and Inert Gas Blanketing
    Suitable for inerting, purging, tank blanketing, oxidation prevention, and pipeline protection in chemical and process-related applications where nitrogen is used to reduce oxygen exposure and improve process safety.
  • Laboratory and Research Use
    Well suited for laboratory instruments, sample handling, analytical testing, and research environments that need a convenient, stable, and on-site nitrogen source without dependence on bottled gas.
  • Laser Cutting and Metal Fabrication
    Recommended for nitrogen-assisted laser cutting, oxidation reduction, and cleaner cutting performance in metal fabrication applications. This is a practical direction for industrial users that want to improve cut quality while avoiding the logistics of bulk bottled nitrogen.
  • Tire Inflation and Service Applications
    Applicable to industrial tire inflation systems, fleet maintenance environments, and service applications where a stable nitrogen source is preferred for controlled inflation performance.
  • General Industrial Inerting and Protection Systems
    Suitable for plants that require nitrogen for oxidation control, moisture-sensitive storage, product protection, or controlled atmosphere applications across multiple departments or production zones.
  • Factories Requiring Continuous On-Site Gas Supply
    Especially suitable for facilities that want to reduce dependence on cylinder delivery schedules, improve gas supply continuity, and gain more stable long-term nitrogen availability through on-site generation.
  • Coastal and High-Humidity Operating Environments
    For industrial facilities located in coastal Philippine cities or other high-humidity environments, an on-site nitrogen generation system can be especially valuable when paired with proper compressed air pretreatment, helping maintain more stable nitrogen purity and long-term operating reliability.
