Dreosti Memorial Lecture 2019

The prestigious SAIRAC Dreosti Memorial lectures will take place in June across the country, where a special international guest speaker will look at R290 and the application pertaining to refrigeration. 

By Grant Laidlaw of SAIRAC

At the inaugural South African Institute of Refrigeration and Air Conditioning (SAIRAC) meeting held in Cape Town on the 17 July 1951, Dr Dreosti was elected the founding president of the association.

Dr Dreosti published over 300 papers in the fields of refrigeration, dehydration, canning and so on. He made a lasting and valuable impact on mankind and indeed made the world a better place.

SAIRAC launched the Dreosti Lecture in 1998, a year after Dr Dreosti’s death in 1997. The Dreosti lecture exemplifies the objectives of SAIRAC to promote the unrestricted dissemination of knowledge and information.

Expert speaker

The 2019 SAIRAC Dreosti lecture is to be delivered by Dr Volkmar Hasse. Dr Hasse was the programme director for ProKlima - GTZ and has vast knowledge and experience relating to all aspects around R290 and the application thereof pertaining to refrigeration. As an imminent authority on the subject, he was an easy choice to make.
