CO₂ technology training for Engineers. CO₂ Academy

More and more people are realizing the many benefits of refrigeration units that use CO₂/R744 as a refrigerant. And in many countries, laws are being passed to drive the transition to nature friendly solutions. Those of us who work with the refrigeration industry are currently seeing a technical revolution take place, and it is essential that we have the right skills to keep up with developments. CO₂ Academy is the natural choice for training in transcritical CO₂ technology. As a engineer it is not only essential to understand the technical aspects of CO₂ technology, but also to acquire the relevant communication skills.
