Finned tubes are the main components of heat exchangers. They are a series of tubes where fins have been added on the outside to increase the contact area with the outside fluid, to exchange heat and between the fluid inside the tube and the fluid outside the tube. Finned tubes are elongated aluminium cladded carbon steel flat tubes with brazed aluminium fins.
Multiple types and shapes of finned tubes exist including round tubes, oval tubes, or flat tubes. Flat tubes, made of aluminium clad carbon steel tubes with aluminium brazed fins, so-called SRC©, are the state of the art for power plant air cooled condensers.
The excellent corrosion and freeze resistant SRC® finned tubes are manufactured at SPX Dry Cooling’s fully owned state-of-the-art factories.
