Health care industry in India is rapidly expanding and to meet increasing requirement of oxygen especially in far flung areas, medical PSA oxygen plants presents an economical and reliable solution. The medical PSA oxygen plant from Airgases Projects in collaboration with Oxymat Denmark offers the state-of-the-art design which ensures reliable oxygen supply to the hospital which is such a critical requirement to them. Airgases Projects with close collaboration with Oxymat Denmark, who are one of world’s most reputed medical PSA technology supplier offers a well proven technology to Indian health care industry. The execution philosophy is based on the core PSA unit with control unit being imported from the technology provider and air supply system sourced in India but from international vendors. This strategy ensures that after sales service for moving machinery is available from within India and directly from OEM in all geographies of the country. The storage vessels are built in Airgases Projects own state of art vessel manufacturing unit. The plants offered by Airgases Projects are of modular design, which can be easily installed and integrated with any existing oxygen supply system, be it from cylinder bank or a cryogenic storage tank or even another PSA system. The advanced central control system of these plants ensures reliable operation.
Special features of our medical PSA plant include:
This Oxymat oxygen generating system is an on-site oxygen production facility. The system includes air compressor, refrigeration air dryer, filtration system,air buffer, oxygen generator and oxygen buffer. The system takes air from atmosphere and separates the oxygen from other gases. This system operates on Pressure swing adsorption (PSA) technology for separating air into its components.
The PSA process is based on the principle that under high pressure, gases tend to be attracted selectively to solid surfaces, or "adsorbed". The higher the pressure, the more gas is adsorbed and conversely when the pressure is reduced, the gas is released, or desorbed.Based on this fundamental principle, gas mixtures such as air are separated.
Ambient air is compressed in a screw compressor to a pressure required for efficient adsorption. Air is first treated to remove oil & dust in series of filters and then moisture is removed through cooling in refrigeration dryer unit. An air buffer is provided to avoid fluctuation in air supply to PSA unit.
As compressed air enters PSA unit, Oxygen is allowed to pass through molecular sieve, while nitrogen is retained. Adsorption occurs at high pressure and desorption at lower pressure. Two adsorber columns with molecular sieve (Zeolite) are utilized and these columns work in alternating operation mode through switching valves operated through PLC i.e. when one column delivers oxygen product the other column is regenerated.
Oxymat oxygen generators are produced in accordance with-
