Product Features
Carbon dioxide compressors (CO₂ compressors) are core equipment specifically developed for pressurizing and efficiently transporting carbon dioxide gas. These products combine safety, reliability, energy efficiency, environmental friendliness, wide operating range, and high efficiency. With their superior quality and stable performance, they have broad application prospects in numerous fields such as petrochemicals, industrial production, automotive manufacturing, pharmaceutical extraction, and food processing. Whether for continuous industrial production or intermittent process requirements, our compressors can handle them with ease.
Core Components
This equipment consists of a compressor air end, intelligent control system, expansion joint, drive motor, circulating cooling system, forced lubrication system, exhaust valve assembly, pistons, and cylinders, working together as a whole. Among these, the compressor main unit, as the core of the entire system, directly undertakes the task of compressing carbon dioxide gas. Its design level and manufacturing precision play a decisive role in the overall working efficiency and gas compression ratio. Leveraging our mature technological accumulation, we ensure optimal matching between the main unit and all auxiliary components, fully maximizing the system's comprehensive performance.

FAQs
Q1: What are the requirements for the quality of the intake gas for the CO2 compressor?
The CO2 gas entering the compressor should be as dry and clean as possible. If the gas contains significant moisture or impurities, it may lead to the following risks:
- Accelerated corrosion or wear of cylinders and valves;
- Reduced service life of piston rings and seals;
- Decreased heat transfer efficiency in the cooling system;
- Potential for liquid hammer incidents caused by liquid water during the compression process.
It is recommended to install a gas-liquid separator and a precision filter upstream of the compressor to ensure the intake gas quality meets equipment specifications.
Q2: What are the differences between a carbon dioxide compressor and a standard air compressor?
Although they share similar operating principles, there are significant differences in design and material selection:
- Differences in medium characteristics: Carbon dioxide liquefies more easily during compression and is sensitive to moisture; discharge temperature must be carefully controlled to prevent liquid formation;
- Different lubrication requirements: CO₂ can chemically react with certain lubricants or dilute the oil film, necessitating the use of specialized CO₂-compatible lubricants;
- Stricter sealing requirements: CO₂ molecules are small and highly permeable, imposing rigorous demands on the materials and design of piston rings and packing seals;
- Corrosion considerations: CO₂ becomes weakly acidic when dissolved in water, so wetted parts must be corrosion-resistant. Therefore, a standard air compressor cannot simply be used for CO₂ boosting.
Q3: What precautions should be taken when the compressor is shut down for an extended period?
If the equipment is scheduled to be shut down for more than one month, the following protective measures are recommended:
- Thoroughly drain residual water from the cylinders and cooling system to prevent freeze damage or internal corrosion during winter;
- Close the inlet and discharge valves, and purge the unit with nitrogen or dry air for protection;
- Disconnect the main power supply and cover the control cabinet to protect against moisture and dust;
- Manually rotate the shaft a few turns every two weeks to prevent the piston rings from sticking to the cylinder walls;
- Before restarting, inspect the lubricating oil for deterioration and check seals for aging or hardening; also, perform a comprehensive pre-start inspection as required.
Q4: Do you offer customized design services?
Yes. We possess mature capabilities for non-standard, customized design. We can provide end-to-end customization services-ranging from conceptual design, engineering calculations, and equipment manufacturing to on-site commissioning-tailored to the user's specific operating conditions and process requirements.
