Flow

A spiral tube heat exchanger is a coil assembly
fitted in a compact shell that optimizes heat transfer
efficiency and space. Every Sentry spiral coil assembly
has welded tube to manifold joints for durability and
strength. The coil assembly is welded to a head and
fitted in a compact shell. The spaces or gaps between
the coils of the spiral tube bundle become the shell
side flow path.

The spiral shape of the flow for the tubeside and
shellside fluids creates centrifugal force and secondary
circulating flow that enhances the heat transfer on both
sides in a true counterflow arrangement. Since there
are a variety of multiple parallel tube configurations
(diameter, number and length), efficiency is not
compromised by limited shell diameter sizes as it is in
shell and tube designs.
The profile of a spiral is very compact and fits in a
smaller footprint than a shell and tube design. Since
the tube bundle is coiled, space requirements for tube
bundle removal are significantly reduced.
When exotic material is required, a spiral tube heat
exchanger minimizes the material used since manifolds
replace the channels, heads and tubesheets of a
conventional shell and tube design. The shell side
is usually smaller than a comparable shell and tube
design and there are no requirements for tube supports
or pass dividers.
