High-purity industrial PSA nitrogen production equipment used in the chemical industry

Features and Advantages

1. High Air Source Quality Requirements

Oil-free or completely oil-free compressed air (typically Class T or Class 0 oil-free certification) must be provided 

to prevent oil contamination of the carbon molecular sieve, which could cause failure.

The purity of the compressed air directly determines the purity and quality of the resulting nitrogen.

2. Extremely High Operational Stability Requirements

PSA nitrogen production is a continuous, uninterrupted process, requiring the compressor to operate reliably 24/7 

with an extremely low failure rate.

3. Energy-Saving and Highly Efficient

Nitrogen production is a significant energy consumer. The accompanying compressor typically utilizes permanent 

magnet variable frequency technology, automatically adjusting production based on demand, significantly reducing 

energy consumption and serving as a core energy-saving component of the system.

4. Stable Pressure

The system provides compressed air at a stable pressure, ensuring that the PSA adsorption tower can switch between 

adsorption and desorption at the operating pressure (typically 7-10 bar), ensuring stable nitrogen production and purity.

5. Reduced Overall Costs

While the initial investment may be higher, its low failure rate, low maintenance costs (the oil-free design eliminates the 

cost of subsequent oil removal filters), and high energy efficiency provide users with lower overall lifecycle costs.
