The invention provides a cooler apparatus and a method use. The cooler apparatus has at least one heat exchange conduit passing through a cooling medium. The method comprises flowing a fluid to be cooled through the at least one heat exchange conduit from a first cooler inlet to a first cooler outlet, to cool the fluid from an inflow temperature to an exit temperature by heat exchange with the cooling medium. In an aspect of the invention, the flow of the fluid through the at least one heat exchange conduit and the flow of the cooling medium are controlled to cause a local increase in a temperature in a selected portion of the at least one heat exchange conduit. This causes deposits of solids to be released from an inner surface of the selected portion of the at least one heat exchange conduit into the flowing fluid. The method may comprise restricting or containing the cooling medium around the selected portion of the at least one heat exchange conduit, and/or controlling the flow of the fluid to be cooled by re-routing the flow path of the fluid through a selected inlet of the at least one heat exchange conduit.
