Low Finned Tubes Production

Production - Low Finned Tubes

Low Finned tube is a finned tube obtained through plastic cold deformation.
The method consists in realizing, from a smooth tube, fins with a particular geometric form without removing material; this plastic deformation causes an increment of heat exchange efficiency, and allows to reduce the heat exchanger size.
