Citrique Belge in Tienen is one of the largest citric acid producers in the world. As a part of their Triple P programme, Citrique Belge also devotes extra attention to the relationship with the environment. When a small number of people living in the vicinity pointed out an annoying noise that was sometimes produced by a number of cooling towers, Citrique Belge decided to investigate how this situation could be rectified.
An oil refinery from the Port of Antwerp asked us if it would be possible to adapt their counterflow cooling tower with axial suction fans so it could still cool the same water flow rate, but to a lower cold water temperature. The cooling tower consists of six cells.
