Efficient solar energy absorbers begin with high thermal conductivity between the fin and tube. The Thermafin welding process actually makes the tube one with the fin and creates a joint at least two times wider than the thickness of the copper fin, resulting in a clean, uninterrupted heat path unlike any other.
Thermafin absorbers have no soldered or crimped seam joints to weaken or fail. The forge welding actually strengthens the joint area, unlike other welding processes, such as ultrasonics, which causes a weakening of the fin around the joint area. Thermafin uses the world's finest solar selective coating on their absorbers. The revolutionary Crystal Clear™ coating was developed by AET/Thermafin as a collaborative effort working with Coating Industry Professionals from broad based backgrounds.
Crystal Clear™ is environmentally benign and boasts an emissivity of approximately 0.10 and absorptivity of approximately 0.95 !!!
