Oxygen Generation Units
Cryogenic Oxygen Plants

Cryogenic oxygen plants are technological systems that produce oxygen by condensing and cooling air to cryogenic temperatures. They are widely used in medicine, industry, and scientific research.

Application & Advantages

An oxygen plant is a comprehensive system for oxygen production, cylinder filling (or monoblock filling), and direct supply to end-users. Based on Pressure Swing Adsorption (PSA) technology, it ensures a continuous oxygen supply.

For facilities with high oxygen demand, it significantly reduces costs by minimising transportation and third-party gas procurement.

ONH Systems offers oxygen generation plants designed and manufactured in-house.

  • Capacity: 0.9–90 Nm³/h
  • Purity: 94 % ± 2 % O₂
  • Pressure: 4.5–6 bar
  • Delivery, installation, and commissioning included
  • Standard or custom configurations available
  • Full compliance with the customer’s technical requirements
  • Technical service and maintenance provided

System Components

  • Main Distribution Board (MDB) — receives and distributes power
  • Air compressor — compresses atmospheric air and feeds it into the oxygen generator
  • Cyclone separator — removes water, oil condensate from compressed air for easier drying
  • Refrigeration dryer — dries air by cooling
  • Air receiver — stabilises pressure fluctuations
  • Main air filters — purify the pneumatic flow
  • Oxygen generator — operates using Pressure Swing Adsorption (PSA) technology
  • Oxygen receiver — equalises pressure surges and provides oxygen storage
  • Switching device — ensures uninterrupted gas supply
  • Cylinder filling stations:
    • Cylinder filling manifold — for cylinder refilling
    • Cylinder discharge manifold — for direct gas delivery to consumers

Oxygen Plant Operating Principle

The equipment functions as follows:

  1. The air compressor compresses atmospheric air and directs it into the air receiver, which stabilises pressure fluctuations.
  2. The airflow passes through the treatment system, where it is cleaned of oil vapours, condensate, and solid particles.
  3. The air mixture enters the separation block containing two types of adsorbents: The first absorbs nitrogen and water vapour from the air mixture; The second releases the absorbed nitrogen into the atmosphere.
  4. The cycle repeats continuously. Oxygen from the receiver is then fed to the compressor for cylinder filling.

Oxygen Plant Configurations

  1. Stationary units — mounted on a vibration-dampened frame, fully assembled and ready for operation. Installed at a designated location within the facility.
  2. Modular block units — installed inside an all-metal container, suitable for operation in various climate conditions. With a prepared installation site, commissioning time is minimised.
  3. Mobile units — installed in a container mounted on a wheeled chassis or skids.

Advantages of Oxygen Plants

  • Cost efficiency — minimal oxygen production costs; payback period is approx. 2 years.
  • Low power consumption — only 0.19 kW per 1 m³ of oxygen.
  • Low maintenance — servicing required only for the screw compressor, air dryers, and filters. Adsorbent replacement is needed every 40,000 — 50,000 operating hours.
  • High reliability — equipped with components from leading global and domestic manufacturers. Each unit undergoes multi-stage quality control and testing, ensuring an uninterrupted 24/7 oxygen supply.
  • Full automation — does not require constant operator presence; remote access is available.
  • Optional features — on request: off-spec gas vent valve, oxygen flow meter, dew point sensors for air and oxygen, automatic signalling for peripheral equipment startup.
