Portable Oxygen Concentrator 10 LPM, purity proven to 93% ±3%.

Why onsite PSA oxygen generation matters

Neometrix has expertise in various engineering domains including Oxygen Generation Plants, complete PC-based automation solutions, controlled monitoring and simulation design architecture, electronics/electrical test benches, fluid systems, chemical processes and chemical engineering, hydraulics, ATF, mechanical, pneumatic, and oxygen/helium (high purity gases).

Amid surge medical-oxygen demand, planning the management of oxygen generation with the right equipment at the right time is vital to a hospital or alternate medical care application. To avoid dependency on oxygen cylinders sourced from outside, healthcare facilities worldwide look to onsite oxygen generation and have implemented the change to produce their own medical oxygen onsite. Medical Oxygen Generators produce gaseous oxygen from compressed air onsite and offer a cost-effective, reliable and safe alternative to traditional oxygen gas supplies such as cylinders or cryogenic liquid.

India's oxygen industry, worth over $2 billion, produces nearly 7,800 MTPD of oxygen, while demand has risen to 5,500–5,800 MTPD. Traditionally, medical oxygen has been supplied from cylinders or liquid tanks — and the biggest problem with gases such as oxygen is transportation. Since 1970, PSA oxygen generators have come into use for medical oxygen gas. These greatly reduce capital cost and offer mobility for the needs of hospitals and the healthcare sector.

Because oxygen has traditionally been delivered from cryogenic sources, medical oxygen specifications required purity greater than 99%. However, extensive clinical trials concluded that 93% ±3% oxygen from a PSA oxygen generator presents no physiological effect on patients — and oxygen generated by PSA generators is therefore acceptable for use and is recognized and permitted by the United States, European and Indian Pharmacopeia.

Technical specifications

System components & their functions

The Portable Oxygen Concentrator 10 LPM consists of the following key components:

• Air compressor: Draws and compresses ambient air as the process feed.
• Cooling coil: Cools compressed air ahead of adsorption, aiding moisture removal.
• Solenoid valve: Switches airflow between the twin PSA towers on a timed cycle.
• Pressure transmitter: Monitors system pressure and reports to the control electronics.
• Oxygen sensor: Measures product-gas oxygen concentration for the digital readout.
• PSA tower (twin): Adsorption columns that selectively remove nitrogen, concentrating oxygen in the product stream.
• Water separators: Remove condensed moisture from the compressed air line.
• Air filter: Removes dust and particulate contamination from the intake air.
• Back pressure valve: Maintains stable outlet pressure to the delivery point.
• Reservoir: Buffers generated oxygen to smooth delivery flow between adsorption cycles.

Applications

The Portable Oxygen Concentrator 10 LPM is intended for medical oxygen supply for patients and other medical needs such as ICU and general oxygen wards, including surge demand scenarios.

• Hospitals & ICUs: Continuous onsite medical oxygen supply for ICU and general ward patients.
• Surge demand support: Reduces dependency on external cylinder supply during periods of elevated oxygen demand.
• Alternate medical care: Portable format suits field hospitals and alternate care facilities.
• Higher-altitude facilities: Rated for reliable operation up to 5000m altitude.

Conclusion

The Neometrix Portable Oxygen Concentrator 10 LPM is a cost-effective, reliable, and low-maintenance solution for facilities requiring onsite medical oxygen. With microprocessor-based control, digital purity and pressure readouts, and a portable, light-weight build rated for higher-altitude operation, it is a robust alternative to cylinder and cryogenic oxygen supply chains.
