SelfChill Trainings

Theory Without Practice Is Empty        –        Practice Without Theory Is Blind

This is our approach: Knowhow and materials to apply it!

To be an expert on solar energy and refrigeration is not common but necessary to find the optimal design of every solar cooling solution. In the frame of our trainings, you are welcome to learn most important basic knowledge on PV-systems, refrigeration machines and get familiar with all necessary components. At the end of the training, you will be able to design, construct and maintain your own solar cooling solution!

What is the objective of a SelfChill training?  

If your business runs well, our business runs well too! This means, it is very important for us to share with you technical knowledge and insights of the cooling solutions you are most interested in. The best way to start is by participating in one of our trainings or by testing a SelfChill finalized system, which includes personalized engineering support. You decide!

 

Last but not least: It is not just about technology, but also about how to generate income by using the SelfChill systems in different agricultural value chains!
