Overview

Onsite oxygen, not cylinder logistics.

Cylinder-based oxygen supply means storage, transport, refilling schedules, and the risk of running out at the worst possible time. A PSA oxygen generation plant removes that dependency by producing medical-grade oxygen from ambient air, onsite, continuously.

The Neometrix PSA Oxygen Generation Plant‑200 LPM is a fully automated, energy-efficient system that produces 93±3 percent pure medical oxygen onsite at 200 litres per minute using Pressure Swing Adsorption (PSA) technology. It eliminates the need for oxygen cylinders, ensuring a continuous and cost-effective supply for hospitals, ICUs, and oxygen therapy units.

The standard skid is built around a screw-type air compressor, a twin-tower PSA unit with Zeolite Molecular Sieves, multi-stage filtration, and a PLC control panel — marked NAMO™‑200 on the unit shown here — running an HMI touchscreen interface. It offers low maintenance, real-time monitoring, and quick installation, and is designed to meet Global Medical Standards, ISO 8573 Class 4 compressed-air quality norms, and applicable safety regulations.

A twin-tower PSA plant that never has to wait for a cylinder delivery.

As a compact, skid-mounted system, the 200 LPM plant functions as an on-site PSA oxygen system, a compact oxygen generator for hospitals, and, in its transportable form, a skid mounted PSA oxygen plant or portable PSA oxygen skid — suited equally to permanent hospital installations and to PSA oxygen plant for emergency use deployments where oxygen has to be available fast, without waiting on cylinder logistics.

Working Principle

PSA technology, four steps, on repeat.

The plant separates oxygen from ambient air using Zeolite Molecular Sieves in a continuous adsorption-and-regeneration cycle — no cryogenics, no bottled supply, no external gas vendor.

Step · 01

Compressed Air Supply

Ambient air is compressed, dried, and filtered to remove moisture, oil, and dust particles via the screw-type air compressor, air receiver, and multi-stage filtration train.

Step · 02

PSA Oxygen Separation

Clean compressed air passes through Zeolite Molecular Sieves, which adsorb nitrogen and let oxygen pass through into the oxygen buffer tank.

Step · 03

Regeneration Cycle

When the first PSA tower reaches nitrogen saturation, the system automatically switches to the second tower, while the first tower vents nitrogen to atmosphere and regenerates.

Step · 04

Continuous Oxygen Flow

The twin-tower cycle repeats without interruption, delivering a continuous supply of medical-grade oxygen at the full 200 LPM capacity.

System Architecture

Three subsystems, one skid.

Air compression, PSA separation, and control & monitoring are handled by three discrete subsystems, integrated onto a single skid and run from one control panel.

SYS · 01

Air Compression & Purification

Screw-type air compressor, air receiver tank, pre-filters and micron filters, refrigerated air dryer, and activated carbon filter remove dust, oil mist, and moisture before the air reaches the PSA towers.

Why onsite PSA oxygen generation matters

The 200 LPM PSA Oxygen Generation Plant is a fully automated, energy-efficient system that produces 93±3 percent pure medical oxygen onsite using Pressure Swing Adsorption (PSA) technology. It eliminates the need for oxygen cylinders, ensuring a continuous and cost-effective supply for hospitals, ICUs, and oxygen therapy units. Equipped with a screw-type air compressor, twin-tower PSA unit, multi-stage filtration, and PLC-based automation, it offers low maintenance, real-time monitoring, and quick installation. The system meets Global Medical Standards, ISO 8573 Class 4 norms, and global safety regulations.

1. Working principle — PSA technology

The 200 LPM PSA Oxygen Generation Plant functions using Pressure Swing Adsorption (PSA), a method that selectively separates oxygen from nitrogen using Zeolite Molecular Sieves. The plant operates through a continuous adsorption and regeneration cycle:

Compressed air supply: Ambient air is compressed, dried, and filtered to remove moisture, oil, and dust particles.
PSA oxygen separation: The clean compressed air is passed through Zeolite Molecular Sieves, which adsorb nitrogen, allowing oxygen to pass through.
Regeneration cycle: When the first PSA tower reaches nitrogen saturation, the system automatically switches to the second tower, while the first tower releases nitrogen into the atmosphere and regenerates.
Continuous oxygen flow: The system operates in a cyclic manner, ensuring an uninterrupted supply of medical-grade oxygen at 200 LPM capacity.

2. Key features & advantages

High-purity medical-grade oxygen production

Generates 200 LPM of 93±3% pure oxygen, suitable for hospitals, clinics, and emergency healthcare units, providing a consistent and reliable oxygen supply without dependence on external vendors or supply chains.

Fully automated system with intelligent PLC control

An advanced PLC with HMI touchscreen gives real-time monitoring; the smart automation system regulates oxygen purity, flow rate, and pressure levels, and safety alerts notify operators of low oxygen purity, power fluctuations, or system malfunctions.

Compact & energy-efficient design

Optimized power consumption keeps operational costs low. The modular, space-saving design is ideal for small and mid-sized hospitals, with self-cleaning filters and an automatic drainage system that minimise maintenance effort.

Robust & reliable industrial-grade components

A screw-type air compressor ensures steady compressed-air supply; a medical-grade air receiver tank stores compressed air for stable airflow; a multi-stage filtration system removes dust, oil, and moisture; and the twin-tower PSA system enables uninterrupted oxygen generation with automatic adsorption-regeneration switching.

Safety & compliance with medical standards

Built-in oxygen purity sensors, pressure regulators, and emergency stop functions are standard. Overpressure protection mechanisms prevent pipeline overloads, a Servo Voltage Stabilizer protects against power fluctuations, and the exhaust gas system safely vents separated nitrogen to prevent contamination.

Quick installation & easy integration

Pre-assembled and tested before delivery, reducing installation time. The plant can be directly connected to hospital oxygen pipelines or cylinder-filling stations.
