Pressure swing adsorption (PSA) process is made up two vessels filled with molecular sieves and activated alumina. Compressed air is passed through one vessel at 30 degrees C and oxygen is generated as a product gas. Nitrogen is discharged as an exhaust gas back into atmosphere. When the molecular sieve bed is saturated, the process is switched to the other bed by automatic valves for oxygen generation.

It is done while allowing the saturated bed to undergo regeneration by depressurization and purging to atmospheric pressure. Two vessels keep working alternately in oxygen production and regeneration allowing oxygen is available to the process.

Before shipment, our engineer will test and running machine firstly.

The raw material is air, pass through air compressor to precision filter.

Dryer use to remove the content of liquid in the air. Using pressure swing adsorption technology separating the oxygen and nitrogen, waste gas will exhaust back to the air. The purified oxygen support to connect to the breath line or filling into oxygen cylinder via oxygen booster and filling manifold.

A whole complete line of PSA oxygen plant including air compressor, filters, dryer, PSA oxygen generator, booster, filling manifold, etc. The size of our machine is 3/5/10/15/20/25/30/40/50/60Nm3/h, those capacity hot selling in our machine, as well as the same size of containerized PSA oxygen plants, fitted into 20 feet or 40 feet tank.

PSA NITROGEN GENERATOR PSA nitrogen generation adopts carbon molecular sieve as adsorbent whose capacity of adsorbing oxygen is larger than adsorbing nitrogen. The two adsorbers (a&b) alternately adsorbing and regenerating to separate oxygen from nitrogen in air to obtain purified nitrogen by Auto-operated valves controlled by PLC
	LIQUID OXYGEN & NITROGEN GENERATOR Our medium size oxygen/nitrogen plants are designed and manufactured with the latest cryogenic air separation technology, which is trusted as the most efficient technology for high rate of gas generation with high purity. We have world-class engineering expertise enabling us to build industrial gas systems in compliance with internationally approved manufacturing and designing standards.
Cryogenic oxygen production line The first cryogenic 50m3 cryogenic oxygen production equipment in Ethiopia 50 cubic meters of cryogenic oxygen was shipped to Ethiopia in December 2020. The equipment, the first of its kind in Ethiopia, has already arrived in the country. Under construction and installation.
