Bio-CO2 production

An advantage of our CO2 liquefaction technology, is the production of liquid bio-CO2 with consistent quality while simultaneously creating additional revenue. Additionally, CO2 recovery and liquefaction technology contributes to reducing carbon emissions. This technology is an essential add-on for biogas upgraders and carbon capture systems. As it enhances the efficiency of the biogas upgrading plant and the applications of the captured gaseous CO2.

CO2 purification

The CO2 liquefaction technology is unique by using clean circular cooling with CO2 as a refrigerant, instead of Freon or Ammonia. Our CO2 liquefier system has a containerized design for plug-and-play installation on-site with a quick start-up.  Purification and liquefaction of the CO2 enables sustainability, by serving as a responsible substitute for CO2 obtained from natural gas. Additionally, liquid (bio)CO2 has numerous applications in many industries, such as the horticulture-, food- and refrigeration industry.
