High-purity oxygen and nitrogen generator NITROBERG® / OXYBERG®

UHPultra high-purityfor the electronics industry

Overview
BERG configures PSA nitrogen, membrane nitrogen and PSA oxygen systems around the purity, flow, pressure and operating profile of a process. The generator is engineered together with compressed-air treatment, buffer storage and downstream equipment. BERG manufactures, integrates and executes the complete project. Compare the separation routes and choose technology matched to the required purity, capacity and installation format.

Technology selection
Choose separation technology based on gas, required purity, flow pattern, pressure and lifecycle cost. PSA covers the full NITROBERG® purity range from 97% to 99.999% and is preferred when the process needs low residual oxygen, stable high purity and engineered capacity. Membrane modules are compact and typically suitable up to about 99.5% for inerting and blanketing; they suit continuous, moderate‑purity duties. Selection boundary guidance: above roughly 99.5–99.9% PSA generally becomes the technically and economically preferred option.

99% | 2.6 | Moderate increase in air demand
99.5% | 2.9 | Key membrane/PSA selection region
99.9% | 3.4 | PSA preference becomes clearer
99.99% | 4.6 | Compressor sizing rises materially
99.995% | 5.2 | High‑purity PSA duty
99.999% | 6.4 | Highest verified portfolio purity

System configurations

• N₂ plug‑and‑play skid: coordinated skid grouping generator, air treatment, vessels, valves, instrumentation and control interfaces for compact indoor installation and defined system interface.
• O₂ plug‑and‑play skid: pre‑engineered oxygen skid integrating generator, treatment, storage, valves and controls for reduced on‑site work.
• Containerised plant (N₂ or O₂): the complete generation chain installed inside an engineered enclosure for outdoor or remote projects where a protected, transportable and pre‑integrated installation is required.

Technical FAQ (selection)

• Should I specify nitrogen purity or residual oxygen? — Specify the process limit that matters. The NITROBERG® range of 97–99.999% nitrogen corresponds to residual oxygen from 3% down to 10 ppm. Avoid selecting a higher purity unless the process requires it.
• When should I choose PSA instead of a membrane for nitrogen? — Membrane is typically suitable up to about 99.5% for inerting and blanketing. Above roughly 99.5–99.9% PSA generally becomes preferred because membrane air demand rises with higher purity.
• Why does nitrogen purity change compressor sizing? — Verified compressed‑air factor rises significantly with higher purity (e.g., 2.9 at 99.5% to 6.4 at 99.999%), so higher purity needs substantially more compressed air per Nm³ of nitrogen.
