Course Details

2 or 4 days

Aeres Tech Training Centre, Zandlaan 27, Ede, Holland. Nearest airport is Schiphol, Amsterdam.

Starting point
The importance of understanding CO₂ refrigeration technology and the essential role of the consultant/engineer in contacts with end users and contractors.

Awareness of the role of the consultant as the linchpin between end users and contractors/suppliers of materials etc.

Learning by doing, learn things today – do things tomorrow, in your own professional situation. 


  1. Explanation of the subject by the instructor.
  2. Discussion and exchange of knowledge and experiences between participants and instructor.
  3. Personal approach – present and wanted/desired.
  4. The participants practise the new behaviour.
  5. Personal action plan for each practised subject. 

Size of the group
7-12 participants
