Ideal for compact and robust heat exchangers
Excellent bending properties and processability
Availability of various dimensions, internal structures and materials

Materials

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.

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

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.

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.

Our Materials

We offer the widest range of material in the industry and can extend it on request in case of special requirements for heat conductivity, mechanical properties or corrosion resistance. Medium-high finned tubes from Wieland Thermal Solutions are available in copper, copper-nickel, aluminium and carbon steel as well as in stainless steel in limited range.
