OTTC

Open Trade Training Centre

Open Trade Training Centre (OTTC) is a leading training provider of commercial and industrial refrigeration, and air-conditioning training in South Africa. Founded in 1992 by Peter and Isolde Döbelin to address the shortage of vocational skill training in the South African refrigeration and air-conditioning industry, the company’s mission is to transfer relevant technical knowledge and work skills to workers, practitioners, entrepreneurs and employers alike.

Today OTTC is renowned for its training excellence locally, internationally and in the neighboring countries. Close to five thousand participants have attended the popular industrial refrigeration training courses at OTTC in Springs, South Africa.

For many years now the German international standards have been found renowned as some of the highest in the world. We at OTTC have chosen to support these values and standards and implement them into our curriculum.



The OTTC team and Isolde Döbelin would like to say thank you for your generous sponsorships to build a German-standard CO2 refrigeration training plant. With your contribution and Christian Richter’s expertise we can transfer German-standard technology to our students. This has brought the OTTC training centre to the next level. Thank you.
