33m³ 4-140bar Oil-free high-pressure oxygen compressor
This is a well-designed and high-performance oil-free high-pressure oxygen compressor. Utilizing four-stage compression technology, it can stably and efficiently boost inlet oxygen from 0.2-0.45 MPa(G) to ultra-high pressures up to 14.0 MPa(G). Its 100% oil-free design ensures absolute cleanliness of the oxygen medium and ultimate system safety, making it an ideal solution for high-pressure oxygen applications.
This series of industrial oxygen compressors is engineered to deliver high-purity, high-pressure oxygen safely and efficiently. Utilizing a 100% oil-free design and robust multi-stage compression, they are the ideal solution for cylinder filling and demanding industrial processes.
| Feature | Description & Benefit |
|---|---|
| 100% Oil-Free Design | A completely oil-free compression chamber eliminates the risk of oil contamination, ensuring the highest oxygen purity and removing safety hazards associated with oil-oxygen reactions. |
| Four-Stage Compression | A unique four-stage structure progressively increases pressure to 15.2 MPa (150 Psig), controlling the compression ratio at each stage to reduce exhaust temperature and enhance equipment reliability and lifespan. |
| High-Efficiency Cooling | The air-cooling system eliminates the need for complex external water cooling, simplifying installation and reducing operating costs, making it ideal for areas with limited water resources. |
| Intelligent Safety Protection | An integrated automatic control system shuts down the unit in the event of overpressure, providing critical protection for both the compressor and the downstream system. |
