Oil-Free CO2 Compressor: High-Efficiency, Contamination-Free Solution for Critical Applications

The Oil-Free CO2 Compressor is a high-performance, energy-efficient solution engineered for handling carbon dioxide (CO2) in demanding industrial and environmental applications. It is ideally suited for CO2 gas recovery, supercritical fluid extraction, carbon capture and storage (CCS), and beverage carbonation systems. Featuring a robust crankcase capable of operating under both negative and positive intake pressure conditions, this compressor delivers reliable performance with flow rates ranging from 30-80 Nm³/h and discharge pressures up to 20-30 bar.

Designed for versatility, the unit is offered in skid-mounted and air-cooled configurations, incorporating three compression stages and four gas cylinders for optimal efficiency. Critical wear parts are constructed from durable, corrosion-resistant materials—including stainless steel gas valves and piping, cast iron casing and crankshaft, and PTFE-filled piston and guide rings—ensuring long-term reliability even in harsh operating environments. The complete system includes the compressor main unit, electric motor, intercooler, start-up cabinet, and all necessary accessories for turnkey operation.


Oil-Free CO2 Compressor

Key Advantages:

  • 100% Oil-Free & Contamination-Free Operation
    Utilizes PTFE-filled piston rings and sealed design to guarantee oil-free CO2 compression, eliminating risks of hydrocarbon contamination—essential for food-grade CO2, beverage carbonation, and high-purity laboratory applications.

  • High Efficiency & Energy Saving
    Engineered with an optimized flow path and multi-stage compression, it achieves low energy consumption and a superior performance-to-power ratio, reducing operational costs in continuous-duty settings such as CO2 recovery systems and industrial gas compression.

  • Robust & Corrosion-Resistant Construction
    Critical components such as valves, cylinders, and pipelines are made of stainless steel, offering excellent resistance to moisture and acidic conditions commonly encountered in CO2 liquefaction and CCS applications.

  • Compact & Skid-Mounted Design
    Pre-assembled on a rigid, compact chassis for easy installation, mobility, and relocation. Minimizes footprint and reduces on-site preparation time and cost—ideal for portable CO2 booster systems and modular gas plants.

  • Maintenance-Friendly & Reliable
    Simplified structural design paired with an efficient air-cooling system reduces maintenance frequency and simplifies serviceability, supporting 24/7 continuous operation in settings like power plants and geological storage facilities.
