High-concentration oxygen generator OXYBERG® 500

for water treatmentmedicalfor aquaculture

Overview
Generate oxygen on site with selectable purity from 90–95% and capacities from 1.5 to 197.4 Nm³/h. OXYBERG® PSA oxygen generators separate oxygen from compressed ambient air using Pressure Swing Adsorption. BERG GaseTech supplies the generator technology and BERG Kompressoren supplies complete engineered packages including compressed-air treatment, buffer storage, control and monitoring, with optional skid or container integration.

How PSA oxygen generation works

• Compressed-air preparation — Ambient air is compressed, dried and filtered to protect the adsorbent beds.
• Nitrogen adsorption — A CWK zeolite molecular sieve adsorbs nitrogen preferentially under pressure.
• Oxygen production — Oxygen-enriched product gas is collected and supplied to the process.
• Automatic regeneration — Alternating vessels regenerate while the controller maintains continuous production.

Notes
Approx. 11 Nm³ of compressed air is required to generate 1 Nm³ of oxygen (ratio broadly consistent across 90–95% purity). Matrix values are for preliminary selection; final sizing must consider ambient conditions, altitude and operating parameters.
