Product Overview: 99.5% Oxygen Plant
Our 99.5% Oxygen Plant is an on-site oxygen generation system that produces high purity oxygen gas from ambient air. Using advanced Pressure Swing Adsorption (PSA) technology, this oxygen generator extracts oxygen directly from the atmosphere, eliminating the need for oxygen cylinders or liquid oxygen deliveries. The system continuously separates oxygen from nitrogen and other air components, delivering a steady flow of oxygen at 99.5% purity (medical grade). This on-site oxygen plant is designed for 24/7 continuous operation, with an automatic start/stop feature that adjusts production to demand. It is a complete turnkey system including an air compressor, air dryer, filters, and the PSA oxygen generator unit, all configured for reliable performance. With capacities ranging typically from a few Nm³/h up to hundreds of Nm³/h (customizable), our 99.5% Oxygen Plant is suitable for medical, industrial, and commercial applications requiring a high-volume, high-purity oxygen supply.
How It Works: PSA Oxygen Generation Principle
The 99.5% Oxygen Plant employs Pressure Swing Adsorption (PSA) technology to separate oxygen from air. Here's a simplified breakdown of the process:
1.Air Intake and Compression: Ambient air is drawn in and compressed. The compressed air first passes through filters and a dryer to remove moisture, oil, and dust, ensuring clean input air for the PSA unit.
2.Adsorption (Oxygen Production): The purified, dry air enters one of two adsorption towers packed with zeolite molecular sieve material. At high pressure, the zeolite adsorbs nitrogen and other trace gases, allowing oxygen to pass through. The oxygen that is not adsorbed collects at the outlet of the tower as a high-purity product stream (typically 93–95% oxygen at this stage). A portion of this oxygen can be diverted to purge the other tower (see below).
3.Regeneration: While one tower is producing oxygen, the other tower (which was previously saturated with nitrogen) undergoes regeneration. The system rapidly depressurizes the second tower, causing the adsorbed nitrogen to be released (desorbed) from the zeolite. The released nitrogen (and other gases) are vented out. In some designs, a small flow of oxygen from the producing tower is used to purge residual nitrogen from the regenerating tower, ensuring complete regeneration.
4.Cycle Switching: The PSA process alternates between the two towers. A sophisticated valve system and PLC controller automatically switch the towers' roles every few minutes – one tower adsorbs while the other regenerates, and vice versa. This continuous cycle maintains a steady output of oxygen. The result is a continuous supply of high-purity oxygen gas at the system outlet.
By leveraging the adsorptive properties of zeolite under pressure changes, the 99.5% Oxygen Plant efficiently separates oxygen from air at near-ambient temperature. The oxygen produced is collected in a buffer tank and can be delivered at a controlled pressure for immediate use or storage. This PSA technology is well-proven and widely used for on-site oxygen generation due to its fast response and ability to produce large volumes of oxygen.

Applications of the 99.5% Oxygen Plant
The high-purity oxygen produced by our plant is versatile and used across multiple sectors. Some key applications include:
● Medical & Healthcare: Hospitals, clinics, and healthcare facilities use on-site oxygen generators as a central supply for patient care. Our 99.5% purity oxygen meets medical standards for oxygen therapy, anesthesia, and life support systems. It can be directly piped into hospital wards, ICUs, and operating theaters, ensuring a continuous oxygen supply for patients in need. This is especially crucial for respiratory treatments and emergency care, as it guarantees oxygen availability even during power outages or supply disruptions (when backed up by an auxiliary generator). On-site medical oxygen plants have become a cornerstone of healthcare infrastructure, providing a cost-effective and reliable alternative to cylinder deliveries.
● Industrial Manufacturing: High-purity oxygen is widely used in various industrial processes. In metal fabrication and welding, oxygen is used for cutting, welding, and brazing metals – pure oxygen enhances flame temperature for efficient metal cutting and welding operations. Industries such as steelmaking and foundries use oxygen to increase combustion efficiency and furnace temperatures. Chemical and petrochemical plants utilize oxygen in oxidation reactions, synthesis processes, and as an oxidizer in certain manufacturing steps. The glass industry employs oxygen-enriched combustion to improve melting efficiency and reduce emissions. By having an on-site oxygen plant, these industries ensure a steady supply of oxygen for their processes without interruptions, and they can scale production as needed. The 99.5% purity oxygen is also suitable for use in laser cutting machines, where high purity improves cutting precision and quality.
● Water and Wastewater Treatment: Oxygen is increasingly used in water treatment to enhance biological processes. Our on-site oxygen generators supply oxygen for aeration in wastewater treatment plants. By injecting pure oxygen into the treatment basins, the dissolved oxygen levels are raised more efficiently than with air alone, accelerating the breakdown of organic matter by bacteria. This can increase treatment capacity and reduce the size of treatment facilities needed. Oxygen aeration is also used in drinking water treatment for oxidation of contaminants and removal of iron and manganese. Municipalities and industrial water treatment operations benefit from on-site oxygen plants by maintaining optimal oxygen levels in their processes continuously.
● Aquaculture and Fisheries: In fish farming and aquaculture, maintaining adequate dissolved oxygen in water is vital for the health and growth of aquatic life. Our oxygen plant can supply oxygen to fish ponds, aquaculture tanks, and hatcheries to ensure high oxygen levels even at high stocking densities. By using pure oxygen, fish farmers can increase stocking density and fish growth rates while reducing stress on the fish. Oxygen is often delivered via diffusers to create fine bubbles that rapidly dissolve in water. This application is critical in intensive aquaculture operations and can help prevent fish kills due to oxygen depletion. The on-site generator provides a reliable source, especially during hot weather or nighttime when natural oxygen levels drop.
● Other Commercial Uses: There are numerous other applications for high-purity oxygen. In food and beverage processing, oxygen can be used for controlled atmosphere storage or in water treatment for food processing. The pulp and paper industry uses oxygen in bleaching processes to reduce the use of chlorine. Mining operations may use on-site oxygen for underground air supply or for oxidation processes in mineral extraction. Hospitality and wellness sectors sometimes use oxygen for wellness therapy or in high-altitude training facilities. Additionally, our oxygen plants can be configured to fill oxygen cylinders for distribution or backup use, which is useful for medical supply companies or remote locations that need portable oxygen.
Regardless of the industry, the LDH 99.5% Oxygen Plant offers a versatile solution to generate oxygen on-site. Its adaptability and reliability make it a valuable asset in any setting where a continuous supply of high-purity oxygen is required.

Frequently Asked Questions (FAQ)
Q: What is the purity of the oxygen produced?
A: Our 99.5% Oxygen Plant produces oxygen at up to 99.5% purity (medical grade). This meets the requirements for medical use and most industrial applications. In some configurations, especially at very high flow rates, the purity might be slightly lower (around 93–95%), but our standard systems are designed to achieve 99.5% oxygen purity at their rated capacity.
Q: How much oxygen can the plant produce per hour?
A: We offer a range of capacities. Smaller units can produce on the order of a few cubic meters per hour (e.g. 5 Nm³/h), while larger systems can produce hundreds of Nm³/h. We will design a system based on your required flow rate. The plant will continuously produce oxygen up to that rated capacity, and it can modulate output if demand is lower. If your demand varies, the automatic controls will adjust production accordingly.
Q: Is the oxygen dry? Can it be used directly for medical breathing?
A: Yes, the oxygen produced is dry (typically -40°C dew point) and clean. For medical use, it is recommended to humidify the oxygen before it is administered to patients (using a humidifier bottle) to prevent dryness of airways. The oxygen from our plant is medically pure and free of hydrocarbons or other contaminants, meeting pharmacopoeia standards when properly filtered. Hospitals commonly use our oxygen in their pipeline systems with humidifiers at the patient end. We ensure the system includes appropriate filters to remove any trace impurities, so the oxygen is safe for therapeutic use.
Q: What are the utility requirements (electricity, space, etc.)?
A: The main utility needed is electricity to run the air compressor and vacuum pump (if applicable) and controls. A typical 20 Nm³/h unit might consume on the order of 15 kW of power. We will provide the exact power requirement for your system. The plant requires a stable electrical supply (with appropriate voltage and phase as specified) and should ideally be backed up by a generator for critical applications to avoid downtime during power cuts. In terms of space, the equipment is skid-mounted and can be installed outdoors (weather-protected) or in a well-ventilated indoor area. We recommend a level foundation and sufficient clearance around the unit for maintenance access. The footprint will depend on the size of the system – we can provide dimensions once the capacity is finalized.
Q: How does the system handle power outages or maintenance downtime?
A: If there is a power outage, the oxygen plant will stop producing oxygen. For critical medical applications, we advise having a backup plan such as an auxiliary generator to power the plant or a reserve of oxygen cylinders to use during short outages. Our plants can be equipped with automatic transfer switches to start backup power and resume operation quickly. In case scheduled maintenance is needed, the plant can be shut down and isolated. Many of our customers have redundant systems or backup cylinders to cover maintenance periods, especially in hospital settings. We design the system to be maintainable with minimal downtime – for example, the PSA towers regenerate alternately, so the process is inherently modular.
Q: What maintenance is required and how often?
A: Regular maintenance is straightforward and minimal. Key tasks include filter changes (air intake filters, oxygen filters) periodically (e.g. every 6–12 months depending on usage and environment), checking and servicing the air compressor (oil changes if it's an oil-injected compressor, filter changes, etc.), and inspecting valves and seals. We provide a maintenance manual with schedules. The molecular sieve in the PSA towers typically lasts many years (5+ years under normal conditions) as long as the air is properly pre-treated; it may need replacement after a long service life or if it gets contaminated. Our team can perform or guide these maintenance activities. We also recommend annual professional servicing to ensure all components are in optimal condition. With proper maintenance, the oxygen plant will operate reliably for a long time.
Q: Can the oxygen plant fill cylinders for use elsewhere?
A: Yes, our oxygen plants can be configured as oxygen generation and filling stations. By adding an oxygen booster compressor and a cylinder filling panel, the system can fill high-pressure oxygen cylinders on-site. This is useful for refilling patient portable cylinders in a hospital or for distributing oxygen to remote locations. We have designs where the oxygen generator runs continuously and the compressor intermittently fills cylinders as needed. The filling system includes safety features like pressure relief and check valves. If cylinder filling is a requirement, we will incorporate the necessary components into the plant design.
Q: Is on-site oxygen generation safe?
A: Yes, on-site PSA oxygen generation is considered safe when proper guidelines are followed. The plant produces oxygen at relatively low pressure (typically <100 psi) and stores only a small volume in the buffer tank, which is much safer than storing many high-pressure cylinders. The system includes multiple safety features: pressure relief valves, temperature sensors, automatic shutdown on fault conditions, and flame arrestors on oxygen lines. Oxygen is a non-flammable gas but supports combustion, so standard precautions apply (keep the area ventilated, away from open flames or sparks, and no smoking). Our installation and operation manual will detail all safety requirements. When installed and used correctly, our oxygen plant is a safe, enclosed system that greatly reduces the risks associated with handling and storing oxygen cylinders.
Q: How does the cost of an on-site plant compare to buying oxygen?
A: Generally, an on-site oxygen plant leads to significant long-term cost savings. While there is an initial investment in the equipment, you eliminate ongoing expenses for delivered oxygen (cylinder rental, delivery fees, and the cost per cubic meter of oxygen). The main recurring cost is electricity to run the plant and routine maintenance. Many of our customers find that the on-site system pays for itself in a couple of years through these savings. Additionally, you gain reliability and independence – no more supply shortages or price hikes affecting you. We can provide a cost comparison analysis for your specific usage to demonstrate the financial benefits.
Q: Can the plant be relocated if our needs change?
A: Yes, the oxygen plant is skid-mounted and can be disassembled and moved to a new location if needed. It's not as simple as moving a single cylinder, but it is feasible – for example, we have helped customers relocate plants when they expanded to a new facility. We recommend involving us in the relocation process to ensure it's done safely and to recalibrate the system if necessary. Some components like the air compressor and dryer may need securing during transit. If you anticipate potential relocation, we can design the system with that in mind (e.g., using flexible connections and labeling components clearly for reassembly). Overall, the modular nature of the PSA oxygen system makes it relatively transportable compared to a large cryogenic oxygen tank, for instance.
