Thermafin designed and introduced to the solar heating industry a complete new generation of high-frequency, forge welded fintubes for thermal absorbers which increased thermal and mechanical durability, conductivity and the overall efficiency of absorber plates.

This new manufacturing process provides complete and permanent bonding of fin to tube. During production of Thermafin's patented absorber fins we use an EMF (Electro Magnetic Field) welding process fusing the fins and tubes seamlessly together.

While these fins are manufactured in Jacksonville, Florida, producers from all over the world have already successfully used Thermafin products for years.
