1.1 oxygen generation system working flow
1.2 ETR Oxygen Generator Discription
With PSA principles,
ETR medical PSA oxygen generator can
produce 93%±3% purity oxygen gas directly from compressed air. Compared with traditional Bulk liquid oxygen and cylinders oxygen,
ETR on-site PSA oxygen generator can
reduce cost down to 50 percentages.
Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.

2. Medical oxygen filling system
2.1 Oxygen Filling system Working Flow
2.2 Oxygen filling system description
Eter oxygen cylinder filling plant is consisted of screw air compressor, refrigerant dryer and filters, air buffer tank, Eter PSA oxygen generator, oxygen buffer tank, oxygen booster and cylinder filling station. It can
produce oxygen with 93±3% purity and fill in cylinders. As a complete system, Eter oxygen cylinder filling plant can be widely used for oxygen gas station and hospitals.
Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with
PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%-95% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4 bar pressure, and with a oxygen booster, the delivery pressure can up to 150 bar.

3. medical compressed air system
3.1 ETR Medical Compressed Air System Working Flow
3.1 ETR Medical Compressed Air System Description
The medical compressed air system consists of the air compressor, general filter, aftercooler, precision filter, desiccant air dryer, air buffer tank, activated carbon filter, compressed air quality monitor, decompressor, valve, pipeline and terminal. The system generates compressed air through an air compressor, removes the impurities, oil mist and moisture in the compressed air through an adsorption dryer filter unit, delivers the air to the air storage tank and supplies it through a pipeline to the terminal equipment in the operating room, ICU and other inpatient wards after decompression.
4. Medical Negative Pressure system
4.1 Working Principle
4.2 Suction unit description
ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system. It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.
