Heat Transfer Surfaces

LL Finned Tube

Double “L” fin is used on applications requiring additional corrosion protection to the surface of the base tube. It is produced similar to “L” fin but has a wider fin base which is overlapped during the winding process.
Operating temperature is a little higher than for L fin.
A wide range of both tube and fin materials are available.
Heat transfer performance can be enhanced by utilising SHE’s (or TFL’s) unique internal solder bonded or pulled in secondary surface/turbulator system.
Our “LL” fin tube can be incorporated into our own exchangers or alternatively purchased separately from our sister company Tube Fins Ltd.
