SIAD Carbon Dioxide Compressors

Wet CO2 and its recovery will put any compression system under stress; the problems arising due to the presence of water need to be addressed in a specific way in order to avoid risks of corrosion or wear. For this reason, thanks to its long experience, SIAD Macchine Impianti has developed a new CO2 piston compressor for the food industry that ensures all the quality standards of the gas, while maintaining high performance.

Performance and Benefits

Food-grade CO2

Completely oil-free operation results in a significant improvement in the purity of the gas, thanks to the design of the distance piece and the use of specific materials for food-grade CO2 application.

  • Standard-type cylinders with special coating for wet CO2 application with wide dimensioned cooling water and gas chambers for low velocities out of the gas chamber, little pulsation, and constant cooling.
  • Separator made of stainless steel to drain off the accumulating condensate more efficiently and well-selected materials for dynamically and statically stressed parts.
  • Oil wiper packing, extra-long distance piece, and oil scraper ring mounted on piston rod for an absolutely oil-free compression.
  • Force-feed lubrication for a sufficient oil supply of the points to be lubricated within the driving mechanism.
  • Piston rod in stainless steel with add of special treatment and/or materials suitable to achieve the maximal hardness for its longest life.
  • Liner in Ni-resist cast iron and nickel plated cylinder in cast iron to prevent corrosion inside the cylinder.
