Quick Detail:
Low Finned Tubes add short fin in the tube wall that greatly increase the surface area over smooth tube. The fins are formed into the tube wall so the outside diameter of the fins are not larger than the pre-finned smooth tube.Energy Transfer is solely focused on producing the largest variety and most complete solutions for finned tubing. Low finned tubes can be provided with a smooth or rifled tube inside surface.
