Design and Function
Type TANKO-RT has a rotating spray head. The rotational movement of this ball-bearing spray head is
achieved by the flow of the cleaning agent without additional mechanical drive energy. The speed at
which the spray head rotates is regulated by the spray pressure of the cleaning fluid. The cleaning agent
exits the nozzle openings of the spray head, covers the interior surfaces of the container to be cleaned,
thereby enabling the cleaning.
Type TANKO-RTS has a rigid spray head. The rotation or radial movement of the spray head is prevented
by a rail that is welded into the hydraulic pipe and combined with a groove in the centering adapter disk.
