ABSTRACT:
A heat exchanger is retrofitted by removing old heat exchange tubes. If there is no access passage into the shell, an access hole is cut in a wall of the shell. Modules preformed from zig-zag elements are introduced through the access passage and assembled into a tube support panel within the shell between adjacent support plates. The heat exchanger is retubed so as to support the new tubes by the existing support plates and by said panels.
