The finned tube bundles are of modular construction,
which facilitate isolation of sections for part load operations.
Tube bundles are rigid, self-contained and designed
for handling as a complete assembly. Lifting lugs are provided on each side frame of tube bundles. The
framework of the tube bundles is usually of galvanized steel.
The finned tubes are supported at regular intervals to
prevent sagging and meshing or deformation of fins.
