Vorteil des Rohrwärmetauschers liegt darin, dass dieser (drei) lösbare Abschnitte (erster und/oder zweiter Abschnitt I 0, 20 und gebogener Abschnitt 6) aufweist, die den Transport zum Montageort und die Montage an einer Einrichtung aufgrund einer Gewichtsreduzierung und besserer Handhabbarkeit der einzelnen Abschnitte erleichtern Advantage of the tube heat exchanger is that this (three) detachable sections (first and / or second section I 0, 20 and bent section 6), which transport to the installation site and mounting on a device due to a reduction in weight and better handling of the individual Facilitate sections

Ein weiterer Vorteil liegt darin, dass die über die gebogenen Rohrstücke 25 geschaffene Fluid- verbindung im montierten Zustand außerhalb des Rohrwärmetauschers verläuft, da somit eine sichere Funktions- und Arbeitsweise des Rohrwärmetauschers gegeben ist.  A further advantage resides in the fact that the fluid connection created via the bent pipe sections 25 runs outside the tube heat exchanger in the mounted state, since thus a reliable function and operation of the tube heat exchanger is provided.
