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 Malaysia’s hot and humid climate, industrial processes are more vulnerable to oxidation, moisture-related instability, and inconsistent gas supply when relying on traditional nitrogen cylinders.

The 99.5% PSA Nitrogen Generator provides a cost-effective and continuous on-site nitrogen solution, making it ideal for applications that require stable nitrogen supply for oxidation prevention, product protection, and general industrial use without the need for ultra-high purity.

The 99.5% PSA Nitrogen Generator is suitable for applications in Malaysia such as:

  • General Manufacturing and Industrial Processing – Provide a stable and continuous nitrogen supply for production lines, pneumatic systems, and protective atmospheres, especially in small to medium industrial facilities.
  • Metal Processing and Fabrication – Reduce oxidation during cutting, welding support processes, and general metal handling, improving surface quality and process consistency.
  • Plastics and Injection Molding – Supply nitrogen for molding, foaming, and processing applications where stable gas flow helps improve product quality and reduce defects.
  • Electrical and Electronics Assembly – Provide nitrogen for assembly processes where moderate purity is sufficient to control oxidation and improve reliability in humid environments.
  • Food and Beverage Packaging (General MAP) – Suitable for nitrogen flushing and packaging applications where cost-effective oxygen reduction is required to extend shelf life and maintain product quality.
  • Chemical and Petrochemical Processing – Used for nitrogen blanketing, purging, and general inerting applications where ultra-high purity is not required but stable supply is essential.
  • Rubber and Polymer Manufacturing – Support nitrogen applications in Malaysia’s strong rubber and plastics industries, improving production stability and reducing oxidation effects.
  • Powder Processing and General Controlled Atmosphere Applications – Suitable for processes that require basic oxygen reduction and stable gas environments.
  • Laboratories and Utility Nitrogen Supply – Provide an economical nitrogen source for non-critical lab use, equipment support, and general plant nitrogen networks.
