Description
Static medical oxygen plants are permanent installations designed to deliver continuous, high-purity oxygen directly to healthcare facilities. These robust systems are ideal for hospitals requiring a dependable, long-term oxygen solution with higher capacity and lower operational costs.
Engineered for efficiency and safety, static plants feature advanced automation, quality controls, and minimal maintenance. They ensure uninterrupted oxygen supply for critical care areas and meet global medical standards for performance and reliability.
Technical Specifications
- Oxygen generation capacity : 40 NM3/hr Medical Oxygen (It will fill 48-cylinders in 8-hrs working)
- Oxygen Purity : 93% ± 3%
- Oxygen pressure from gas generator : 4.5 Kg/cm 2 g
- Oxygen Cylinder filling pressure by booster compressor : 150 Kg/cm 2
Cost Economics
- Cost of Oxygen generation is very less. This is very economical as compared to using liquid Oxygen tanks.
- Due to big cost difference, you will get enormous cost saving which will give you payback in around 1-year time.
- The only running cost in this Oxygen plant is of Electrical power.
Salient Features
- Start-up time is only 5-minutes to start getting Oxygen.
- Automatic pressure switch on storage tank Switches OFF & Switches ON Oxygen plant automatically as per your Oxygen consumption and Oxygen demand.
- It is fully automatic unit, so no operator required.
- Maintenance is negligible. Only running machine is Air compressor.
- Life of Molecular Sieves is around 10-years. So for whole life time of Oxygen plant there is no cost of Molecular Sieves replacement
Equipment Description
The Gas generator has following main equipment :
- One Screw type Air compressor.
- Refrigeration Air dryer.
- Oxygen Generator with molecular sieves.
- PLC Control Panel.
- Oxygen purity analyzer.
- High Pressure Oxygen compressor with cylinders filling station.
- Oxygen cylinder manifold for cylinder filling.
Air Compressor & Refrigeration Air Dyer
- Maintenance free lubricated Screw compressor is provided which supplies compressed air for Oxygen generation. Filters are provided in Air delivery line.
- It has Air cooled after cooled after cooler so no cooling water required.
- It has air receiver with automatic drain value.
- A Refrigeration Air Dryer is provided to dry the compressed air.
Oxygen Generator
In Oxygen generator unit, Molecular Sieve adsorbs Nitrogen from Air, so Oxygen comes out as product gas. In this process, ambient air is compressed, conditioned and filtered through synthetic minerals (zeolites) under pressure, when Nitrogen is selectively adsorbed while oxygen pass through the zeolites and comes out as a product gas.
Oxygen Booster Compressor
- This is of 40M 3/hr capacity for filling 48 cylinders in 8 hour working.
- Oxygen is produced at 4.5 kg/cm2g pressure from oxygen generator and it will be boosted to 150 kg/cm2g pressure for automatic cylinder filling application. For this, we have included one oil free oxygen booster compressor in our supply. It is air cooled compressor. This is Imported Compressor.
Oxygen Analyzer
We provide an ON-LINE digital oxygen analyzer with alarm system. It has adjustable set point and alarm system. It continuously shows O2 purity on control panel with digital indication. Its chemical sensor is of Citi-UK . Its range is up to 100% Oxygen.
PLC Control Panel
For automatic control of Oxygen generator a PLC control panel is included in our supply.
Cylinder Manifold
We supply a cylinder manifold of 12-cylinders (6 + 6) that are filled at high pressure from the oxygen booster compressor.
Scope of Supply
- One Screw type Air compressor with Air Dryer.
- Multistage oil filters in air line.
- Air receiver with Instruments.
- Oxygen unit with valves, molecular sieves and Activated Alumina.
- Digital Oxygen Analyzer.
- Oxygen flowmeter.
- One Oxygen buffer vessel.
- Dust and Bacteria filter in outlet line.
- One Oxygen Booster compressor for cylinder filling.
- Oxygen cylinders manifold.
- Electrical Control Panel with PLC.
- All interconnected piping & cabling within Oxygen plant.
- Supervision of erection and commissioning at site.
- Assembly of Oxygen generator in 20-ft. size container.
Automation and Interlocks
The Gas generator is fully automatic . Upon starting, Oxygen becomes available within 5-minutes . No continuous supervision is needed. You will get alarm on Control panel in case of following abnormalities:
- Low Compressed air supply pressure.
- High Oxygen pressure at booster discharge.
- Low oxygen purity.
