Oil-free compressed air systems
BERG offers integrated compressed air packages combining KOMPBERG compressors, DRYBERG dryers and PUREBERG multi-stage filtration to deliver clean, dry and reliable compressed air for cleanroom and electronics applications.

• KOMPBERG — Oil-free rotary screw compressors (ISO 8573-1 Class 0) for contamination-free compressed air
• DRYBERG — Refrigerant and desiccant air dryers to achieve required dewpoints for sensitive electronics processes
• PUREBERG — Filtration systems removing particulates, oil aerosols and odours to support ISO 8573-1 Class 1 performance

On-site nitrogen generation — NITROBERG (PSA technology)
PSA nitrogen generators eliminate cylinder dependency and deliver consistent high-purity N₂ at the purity your process requires. NITROBERG supports SMT assembly, wave soldering, selective soldering, nitrogen blanketing and component storage with cost reductions versus cylinders of up to 80% in continuous operations.

NITROBERG specification table
Technology: PSA (Pressure Swing Adsorption)
N₂ Purity Range: 99.9% – 99.999%
Flow Range: 1 – 500 Nm³/h
Feed Gas: Compressed Air
Outlet Pressure: 5 – 10 bar

Applications across electronics manufacturing

• SMT reflow soldering — nitrogen to prevent oxide formation and improve wetting and joint quality
• Wave soldering — N₂ blanketing to reduce dross, improve wetting and extend solder pot life
• Selective soldering — inert atmosphere at the nozzle for reliable through-hole joints
• Component & PCB storage — nitrogen cabinets and chambers for moisture-sensitive and oxidation-sensitive devices
• Laser cutting & marking — nitrogen as cutting assist gas for clean, oxide-free edges; compressed air for beam path purging and pneumatics
• Cleanroom compressed air — ultra-clean, dry, oil-free air for pneumatic tools, pick-and-place machines, test equipment and automation

Why switch from cylinders to on-site N₂ generation

• Cost reduction: typical gas cost savings of 60–80% for continuous operations
• Purity control: configure N₂ purity precisely to your process (avoid over-specification)
• Uninterrupted supply: 24/7 on-demand production from existing compressed air
• Scalability: modular systems that grow with production
