AIR-COOLED HEAT EXCHANGERS

12.2.2 High-fin tubing

Finned tubes are almost always used in air-cooled exchangers to compensate for the low air-side. Radial (annular) fins arranged in a helical pattern along the tube are used. The fin heigh is significantly larger than that of the low-fin tubes used in Hence, this type of tubing is referred to as high-fin tubing.

Various types of high-fin tubing are available, including:

Integrally finned

Medium-high finned tubes made of copper and copper alloys


GEWA-D finned tubes made of copper and copper alloys are available in a wide range of sizes and withstand the highest mechanical and thermic stress. They are specially made for the individual geometries of complex heat exchangers. Copper offers the highest heat conductivity of all technical metals. It is superior in processing, hygienic and a corrosion resistant solution.

Medium-high finned tubes made of aluminium


GEWA-D finned tubes made of aluminium are specifically used in light-weight applications. Aluminium combines highest ductility with reasonable heat conductivity.

NEW: Medium-high finned tubes made of carbon steel

GEWA-D finned tubes made of carbon steel can be used in applications such as solid-fuel boilers or storage tanks. The significantly enlarged surface area compared to plain tubes allows compact solutions. Ready to install heat exchangers can be an interesting alternative solution for heat exchangers made of costly materials.

NEW: Medium-high finned tubes made of stainless steel

GEWA-D medium-high finned tubes made of stainless steel can be used for condensing boilers or domestic hot water applications. Due to the enlarged outside heat transfer surface area the required tube length can be reduced and thus costly material can be saved.
