Heat Transfer Surfaces

G Finned Tube

High conductivity fin tube ideal for elevated temperature applications.
“G” fin have a helical groove formed in the tube surface with an uplift of metal each side which, when peened back into the fin, grips it securely. This ensures high heat transfer as well as producing a secure mechanical bond.
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 “G” fin tube can be incorporated into our own exchangers or alternatively purchased separately from our sister company Tube Fins Ltd.
