Generally, a PSA system includes multiple components, such as compressors, air dryers, adsorption towers, control panels, and nitrogen storage tanks. Sufficient space should be left for each component to facilitate routine maintenance and inspections.
• Ventilation and Temperature: The installation location should provide good ventilation to avoid system overheating. PSA nitrogen generators typically operate best in an environment with temperatures ranging from 15°C to 35°C, avoiding extreme temperatures that could negatively affect system performance.
• Dry and Clean Environment: The installation environment should be kept dry to prevent moisture from affecting the system’s internal electronic components and the performance of the adsorption towers. The area around the equipment should be clean to prevent dust from entering the system, especially in compressed air pipelines and adsorption towers.

1.2 Electrical and Air Supply Preparation

PSA nitrogen generators require reliable electrical and compressed air supplies. Ensure the following equipment meets system requirements:

• Electrical Supply: Based on the power requirements of the equipment, confirm that the power voltage, current, and grounding system meet the equipment’s specifications. Typically, PSA nitrogen generators use a 380V or 480V three-phase power supply. Refer to the equipment’s technical manual for specific requirements.
• Compressed Air Supply: The main operating principle of PSA nitrogen generators is to use compressed air for nitrogen separation. Ensure the connected air compressor can provide the required airflow and pressure. The required compressed air flow is typically between 10 and 100 cubic meters per minute, with a pressure range of 6 to 8 bar.
• Air Drying: To ensure the proper operation of the adsorption tower, the system requires dry and clean compressed air. It is recommended to use a high-efficiency air dryer to prevent moisture from entering the system.

1.3 Safety and Regulatory Requirements

Safety is always the most important consideration during installation. Installation should comply with the relevant national or regional regulations, and the following requirements should be met:

• Electrical Safety: During installation, ensure that the electrical system and equipment are properly grounded to prevent electrical fires or shocks.
• Gas Leak Detection: During installation, check all connection points to ensure there are no gas leaks in the pipeline. Use appropriate gas detection instruments to detect leaks of nitrogen or compressed air.
• Fire Safety Equipment: Fire extinguishers and other fire safety equipment should be placed near the installation area to ensure that any potential fire hazards can be addressed promptly.

II. System Components and Functions of PSA Nitrogen Generators

A PSA nitrogen generator system typically consists of several key components, each with a specific function. Understanding the role of these components will help ensure that each part is properly installed and calibrated during the installation process.

2.1 Adsorption Tower

The adsorption tower is one of the core components of the PSA nitrogen generator. Its main function is to adsorb oxygen, water vapor, and carbon dioxide from the air using molecular sieve media, releasing pure nitrogen. PSA nitrogen generators typically use two or more adsorption towers to operate alternately, ensuring a continuous supply of nitrogen.

• Installation Requirements: The adsorption tower should be installed on a firm, stable foundation and should be protected from long-term exposure to moist environments to prevent the molecular sieve from being affected by moisture.

2.2 Air Compressor

The air compressor provides the compressed air required for the PSA system. Compressed air typically comes from the factory’s compressed air system but can also be supplied by a dedicated air compressor.

• Installation Requirements: Ensure that the air compressor’s flow rate and pressure meet the PSA nitrogen generator’s needs, and that the air entering the compressor has been processed by an efficient air dryer to minimize moisture content.

2.3 Air Dryer

The air dryer’s primary role is to remove moisture from the compressed air, preventing water from entering the adsorption tower and ensuring long-term, efficient operation of the molecular sieve.

• Installation Requirements: Ensure that the air dryer is tightly connected to the outlet of the compressor, and regularly clean the filters as needed.

2.4 Control Panel

The control panel is the “brain” of the PSA nitrogen generator, responsible for monitoring and controlling the system’s operation. It adjusts nitrogen purity, flow rates, and other parameters in real-time to ensure stable system operation.

• Installation Requirements: The control panel should be installed in a location that is convenient for operation and monitoring. Ensure correct cable connections and avoid long-term exposure to high temperatures or moisture.

2.5 Nitrogen Storage Tank

The nitrogen storage tank stores the nitrogen produced and supplies it to downstream pipeline systems through a pressure reduction device. The tank’s capacity should be selected based on the required nitrogen demand.

• Installation Requirements: The storage tank should be placed on stable ground and should not be exposed to direct sunlight or high-temperature environments for long periods.
