A control installation for solid cleaning members circulating in a heat exchanger includes interception arrangements interposed on the heat exchanger outlet pipe, a return pipe which recycles toward the inlet pipe a return flow containing the solid cleaning members, and a control device for the solid cleaning members. Between the interception arrangements and the control device there is a concentration device dividing the return flow into two parts. The return pipe is part of circulation arrangements which generate a counter-current flow through the interception arrangements and which include suction arrangements in line with the interception device to take up the solid cleaning members retained thereby.
