Harsiddhi Air Solution is an expert in designing and building PSA (Nitrogen) Plants which are on-site gas generation systems that produce high-purity nitrogen on or near your premises. Our systems are designed for industrial and medical processes while ensuring reliability, energy-saving, and low operating costs.
So what is a PSA Nitrogen Plant?
A PSA Nitrogen Plant separates nitrogen from compressed air using Pressure Swing Adsorption (PSA) technology. It works by selectively adsorbing oxygen and other trace gases.
In other words PSA Nitrogen Plant is
- Ambient air is compressed, filtered, and dried.
- The clean compressed air is passed into the adsorption towers which contain Carbon Molecular Sieve (CMS).
- The CMS adsorbs oxygen and other impurities and nitrogen passes through as the product gas.
- The system consists of two adsorption towers which operate alternately. While one adsorption tower is producing nitrogen, the other is regenerating (desorbing the adsorbed oxygen) to ready for the next cycle.
- Basically, this cycle allows for a continual supply of nitrogen at the required purity and flow.
Advantages of using PSA Nitrogen Plant
High Purity & Reliable Quality
- Our PSA Nitrogen Plants provide nitrogen with high purity (up to 99.999%, depending on application) with consistent pressure and flow stability.
Economical & On-Demand
- Producing nitrogen at your site means you pay for the nitrogen once and don’t incur any repetitive paybacks for gas cylinders, logistic or storage. The overall operational cost is considerably lower than purchasing bottled or liquid nitrogen.
Energy Savings & Maintenance Free
- The design priority of less moving parts, efficient adsorbent media and automated switching means less downtime and, therefore, less maintenance.
Flexible Installation & Operation
- Applicable in a range of industries — food and beverage, pharmaceuticals, electronics, metal processing and chemical plants. The system is customizable to your flow, purity and pressure needs.
Uses of PSA Nitrogen Plants
- Food & Beverage: Nitrogen blanketing, packaging and shelf life improvement.
- Pharmaceutical & Laboratory: Inerting atmosphere generation and product protection.
- Electronics and Semi-Conductors Manufacturing: Manufacturing in moisture-free and oxygen-reduced environments.
- Metal & Heat Treatment: Processing in inert gas during annealing, sintering.
- Chemical & Petro-Chemicals: Purging, inerting, line blanketing.
(And many other industrial usages too.)
How PSA Nitrogen Plants Functions — Step by Step
- Air Compression & Pretreatment – An air compressor compresses ambient air. The result air is dried and filtered to eliminate moisture, oil and particulate contamination.
- Adsorption Phase – The pre-treated compressed air enters the first adsorption tower, which includes CMS. The system adsorbs unwanted gases and oxygen; nitrogen flows through to the receiver tank.
- Switch & Regeneration – After the adsorbent CMS in the first tower has become saturated, the system will switch to the second tower for adsorbing. The first tower is desorbed (depressurized) to regenerate CMS for the next cycle.
- Nitrogen Storage & Distribution – The nitrogen generated will be stored in a buffer tank/receiver and distributed to your process at the required pressure.
- Control & Monitoring – Newer systems will use PLC/SCADA for automation, remote monitoring, alarms, and optimized functionality.

Technical Specifications for PSA Nitrogen Plant
- Flow Rate: Varies by model (e.g. from 5 Nm³/h to several thousand Nm³/h )
- Purity: 95% to 99.999% (relative to application & specification)
- Pressure: Typically around 0.6-1.0 MPa or as required by application
- Dew Point: As required to protect CMS, generally –40 °C or better to upstream pre-dryer.
- Automation: PLC control, remote monitoring, automatic switching of towers.
Installation, Maintenance & Life Span of Your PSA Nitrogen Plants
- Installation: Fast, modular skid-mounted systems reduces installation time and site disturbance
- Maintenance: Routine filter changes, monitoring activated carbon condition, and checks at intervals. If well maintained, the CMS bed should last several years.
- Life Span: With correct application many systems will provide 10 + years with little service intervention while following best practices.
Frequently Asked Questions About PSA Nitrogen Plants
Q: How pure will the nitrogen produced by a PSA Nitrogen Plant be?
A: Depending upon design and requirements, purity will range from 95% up to 99.999% nitrogen.
Q: Is generating nitrogen on-site better than cylinders?
A: Most definitely — on-site nitrogen generation is consistent, efficient for cost savings, and you won’t have to think about cylinder logistics or deliveries.
Q: Can a PSA Nitrogen Plant run continuously?
A: Absolutely — modern PSA plants are built to run 24/7 with minimal supervision.
Q: What industries are your PSA Nitrogen Plants used most?
A: Industries like Food & Beverage, Pharmaceuticals, Electronics, Metals, Chemical Processing, and Research/Labs.
Q: What will I need to know before selecting a plant size?
A: You need to know the nitrogen flow requirement (Nm³/h), purity, pressure, and where the unit will be located, and we will customize accordingly.
