High-concentration oxygen generator OXYBERG®

dryfor biogas plantindustrial

Overview
Skid-mounted, pre-engineered OXYBERG® PSA oxygen generator packages for on-site oxygen production. Systems integrate PSA oxygen generation, compressed-air treatment, buffer storage, monitoring, piping and electrical wiring on a common metal skid to simplify installation and commissioning.

Typical package contents

• OXYBERG® PSA oxygen generator (model-dependent)
• Oxygen purity and pressure sensors
• Compressed-air treatment: filtration, water separator, adsorption dryer
• Air receiver and oxygen buffer receivers (volume per model)
• Oxygen vessels and accessories
• Pre-installed piping and electrical wiring on skid frame
• Documentation: assembly layout, P&ID/R&I, plant description, electrical consumer list, O&M manual, spare/wear parts list, wiring and terminal diagrams, material evidence
• Optional integrated air compressor or configuration for external compressed-air supply

How the skid-mounted system works

• Compressed air preparation: Ambient air is compressed, dried and filtered
• PSA oxygen generation: Molecular sieve separates nitrogen, producing enriched oxygen
• Oxygen buffer storage: Produced oxygen is collected and stabilised in receivers
• Controlled supply: Monitoring maintains target purity and delivery pressure

Design features and system advantages

• Siemens PLC and HMI process control
• Continuous oxygen purity and pressure monitoring
• Integrated adsorption dryer and compressed-air filtration
• Pre‑installed piping and electrical wiring for faster on-site integration
• Designed for continuous-duty operation
• Options for booster, high-pressure storage and cylinder filling

Integration and optional items

• Optional integrated air compressor or connection to site air
• Sized oxygen buffer storage and surge capacity
• Remote monitoring and alarm integration
• Oxygen booster and high-pressure storage integration
• Skid or containerised configurations
• Commissioning, validation and technical support services

Applications (examples)

• Medical oxygen supply (project-specific validation and approvals required)
• Water and wastewater treatment: oxygen enrichment for biological processes
• Aquaculture: dissolved-oxygen control
• Glass and combustion industries: oxy-fuel processes and melting
• Metals industry: cutting, welding and process oxidation
• Biogas plants: micro-oxygen dosing for desulphurisation
• Mining and leaching processes requiring controlled oxidation

Data typically required for an engineered proposal

• Required oxygen flow (Nm³/h)
• Target oxygen purity and outlet pressure
• Daily operating hours and load profile
• Installation country, altitude and ambient temperature
• Application, applicable standards and approvals
• Required redundancy or backup supply
• Preferred installation: indoor, skid-mounted or containerised

FAQ — selected answers

• What is included in an oxygen generator skid? Depending on the package: OXYBERG® PSA generator, air treatment components, receivers, monitoring, piping, wiring and optional compressor.
• Is the compressor included? The compressor is optional; BERG can integrate a correctly sized compressor or configure the skid for an external compressed-air supply.
• What oxygen purity can the skid produce? Configurable typically between 90% and 95% oxygen; available output depends on model and site conditions.
• Is the system plug-and-play? The skid is substantially pre‑assembled; site foundations, ventilation, utilities, installation checks and commissioning are required.
• Can a booster and cylinder filling be integrated? Yes — boosting, high-pressure storage and filling stations can be integrated per project requirements and regulations.
• Can the skid be used for medical oxygen? OXYBERG® technology can be part of a medical oxygen solution, but full system validation and approval are required for medical use.
