Air separation - the process of isolating atmospheric gases such as oxygen, nitrogen, and argon - relies on technologies like cryogenic distillation, membrane separation, pressure swing adsorption (PSA), and chemical absorption. Ambient air, composed of roughly 78% nitrogen, 21% oxygen, and 1% argon, CO₂, and trace gases, is first compressed, then cooled in a “cold box” where individual components liquefy at different temperatures and are drawn off under controlled conditions. Once separated, these gases are recompressed for storage, transportation, or further on-site use.

The purity and reliability of filtered air are critical: hydrocarbon vapors and lubricant carry-over in feed air can foul molecular sieves, causing blockages and performance loss. Conventional filters - coalescing oil separators combined with activated-carbon beds - gradually saturate, risking breakthrough contamination that jeopardizes both process uptime and product quality.

As the cornerstone of any air separation unit (ASU), the compressor’s performance dictates overall plant efficiency and stability. ADEKOM brings over 20 years of dedicated experience in designing oil-free and oil-lubricated compressor packages, as well as turnkey purification systems, to ensure an uninterrupted supply of ISO 8573-1 Class 0 oil-free air. Our solutions have been deployed in hundreds of ASU projects worldwide, delivering high-purity gas for applications across metallurgy, petrochemicals, chemicals, machinery, electronics, and aerospace.

• Oil-Free Design: German-engineered supercoated rotors and housings eliminate any risk of lubricant carry-over, guaranteeing ISO 8573-1 Class 0 purity.
• Two-Stage Compression: Ensures stable discharge pressures, with minimal internal leakage and reduced wear parts for long maintenance intervals.
• Wide Power Range: 7.5 kW to 400 kW models to match feed-air requirements in ASUs of all sizes.
• Low Noise & Vibration: Direct-drive configuration minimizes mechanical losses and foundation requirements.

• Patented Oil-free Converter: Transforms any trace oil in the airstream into harmless water and carbon dioxide, certified to achieve a residual oil concentration one-fifth of the ISO 8573-1 Class 0 limit.
• Maintenance-Free Module: The conversion system requires no cartridge changes, extends the life of downstream high-efficiency and sterilizing filters, and eliminates the unpredictability of coalescer saturation.
• Cost Savings & Risk Reduction: Avoids recurring filter replacements and minimizes the risk of contamination incidents, protecting product integrity and corporate reputation.

• Modular Upgrades: Retrofit existing oil-lubricated screw compressors or targeted plant air points to full oil-free performance.
• Flexible Deployment: Skid-mounted or panel-mounted solutions integrate seamlessly with current installations, reducing capital expenditure and downtime.

Beyond compressors, ADEKOM provides complete ASU support equipment - including booster compressors for high-pressure oxygen or nitrogen circuits, nitrogen recirculation compressors, and, where required, argon compression units. We engineer twin-process packages (e.g., primary N₂ feed plus N₂ recycle) and supply all ancillary systems such as inlet filtration, aftercoolers, and instrumentation. With our extensive compressor portfolio and deep air-separation expertise, ADEKOM delivers turnkey, high-purity gas solutions that optimize performance, reliability, and lifecycle value in every air-separation application.
