Product Description
A fin tube is a tube that has lots of fins around the outside surface.
These fins act as a filter and a mechanism to transfer heat from the
material inside the tube to the outside space or vice versa.
Fin tubes are used in applications that require a transfer of heat
from a hot fluid to a colder fluid through the tube's wall.
