1. A device for reducing fouling in a heat exchanger tube, comprising:
(a) an elongated displacement body configured to be inserted in a heat exchanger tube to reduce the flow cross-sectional area in a portion of the tube, wherein the displacement body is a hollow body having a closed shell, which defines the outer contours and shape of the displacement body and encloses an inner void space, and
(b) a mount connected to the elongated displacement body for attaching the device to an end of the heat exchanger tube, the mount being configured to hold the displacement body, when inserted into the tube, in a spaced relationship to the inner surface of the tube, wherein the mount comprises a plurality of support members radially extending from the surface of the displacement body, wherein the support members each have a recess at the side which is to face the heat exchanger tube, the recesses being configured to mate with the wall of the heat exchanger tube.
