Open Trade Training Centre
Open Trade Training Centre (OTTC) is a leading training provider of commercial and industrial refrigeration and air-conditioning in South Africa.
The OTTC was founded in 1992 by Peter and Isolde Döbelin.
Their dream was to address the shortage of vocational skills training in the South African refrigeration and air-conditioning industry.
Therefore OTTC’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 also in the neighbouring countries.
Close to five thousand participants have attended the popular industrial refrigeration and air-conditioning training courses at OTTC in Springs, Gauteng, South Africa.
For many years now German international standards are renowned to be of the highest in the world.
We at OTTC have chosen to support these values and standards and to implement them into our curriculum.
The OTTC team lead by Isolde Döbelin would like to say thank you for your generous sponsorships.
With your contribution we have built a German-standard CO2 refrigeration training plant.
