Oil-Free Carbon Dioxide Compression for Gas Recovery
The PUFCO oil-free CO₂ compressor pressurizes carbon dioxide gas for recovery, transfer and process use. It provides the compression step needed to move recovered CO₂ from the available source pressure to the receiving system.
CW-Series Models for Different Process Requirements
The CW series includes models with different flow rates, discharge pressures and motor ratings. Model selection should match the gas inlet conditions and the required delivery duty. The technical table lists individual model specifications, electrical supply options, connections, weights and installation dimensions.
CO₂ recovery applications include recovery of used gas from liquid CO₂ extraction processes. Larger CO₂ compression systems are also used in urea synthesis; contact our team to discuss the equipment and operating conditions for your project.

PUFCO oil-free CO₂ compressors are used to pressurize carbon dioxide gas for recovery and transfer, including recovery of used CO₂ gas from liquid CO₂ extraction processes. Larger carbon dioxide compression systems also serve urea synthesis installations. The appropriate compressor should be selected for the gas inlet conditions, required flow and delivery pressure of the individual process.
Frequently Asked Questions
Q1: What is an oil-free CO₂ compressor used for?
▼A1: It pressurizes carbon dioxide gas for recovery, transfer and process use. The compressor is selected to raise the available gas pressure to the level required by the receiving system.
