Eltherm SA takes the concept of ‘heat tracing’ and uses it to improve client products, increase their energy efficiency and minimise break-downs on their production lines. Zweli Dladla and his company Eltherm SA was built on the opportunity that he and his partners recognised for bringing heat tracing to SA. Heat tracing is a technology that enables manufacturers of products like bitumen and chemicals and in industries like food processing, to maintain heat during the production process.
