Welcome To



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, this legacy continues under the leadership of Isolde Döbelin and a highly qualified professional training team. All members of the training team are exceptionally knowledgeable professionals and have extensive local and international practical experience of the industry and its technology. Together, the staff take pride in the company philosophy of training excellence, and have tailored the courses to cover the entire spectrum of technical, theoretical and practical knowledge.

OTTC believes the quality of training must be relevant, and prepare the learner for all kinds of situations encountered in the workplace. As a result of this, the courses are not structured to purposely cover a prescribed curriculum, nor does OTTC deliberately train to prepare candidates for examinations. At the same time, the company has the advantage of not limiting its training to conform, but enjoys the freedom to include technical expertise, and skills beyond the prescribed scope, and ensures that all training aspects are fulfilled to the latest, state-of-the-art requiements.

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

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 thank you for your generous sponsorships  building a German-standard CO2 refrigeration training plant. With your contribution and Christian Richter’s expertise we can now transfer German-standard technology to our students. This has brought the OTTC training to the next level. Thank you.
