Air Cooled Heat Exchangers are generally arranged as
tube bundles side by side or mounted one over the
other. The principal parts of tube bundles are headers
and finned tubes (which has spiral wound or
fins upon the tubes). The process fluid is circulated inside the tube bundle.
Axial flow fans are employed to move air uniformly
across the tube bundles to cool/condense the process
fluids. The fans principal can be driven by electric motors
either directly or through V belt/HTD belts or
Plenum Chambers distribute the air uniformly over the surface of tube bundle. Supporting structural is
used to mount theprincipal tube bundle assembly.
Platforms, grating and walkways are provided to access
the headers and the tube bundles for
The construction of air fin cooler structures are
completely bolted type, to enable easy erection and
These heat exchangers are usually suitable for outdoor
installation and in some cases they are mounted on
pipe rack to save the floor space requirement.
