The Challenge

As Harsco was using smelting process to extract base metal by applying heat to the ore so the hot slag which is a by-product of smelting has a very high temperature which has to carried out by the loader machine and it makes impossible for the operator to sit in the driver’s cabin. So the task assigned to us was to cool down the temperature of Slag Transporting Vehicle from 250°C to 50-60°C each time it came out with the hot slag.


Our team visited the site at Dolvi and after proper analysis we gave complete solution of High static unit of 20000 CFM capacity having top discharge with well-designed form of duct & plenum with grills to cool their machines and there is no other way to run the duct as it is open area.


Their Management is highly satisfied with the performance of cooling as evapoler team got successful in achieving the desirable temperature and provided the best possible solution.
