    This is new improved method of triple ultrasonic welding. Main point is to increase contact area between cooper tubes and absorber and get better solar efficiency, as final result.

Thermal loses are also reduced to maximum. We use double chamber profile for body of the Werner solar collector, filled with polyurethane.

Collector body is two chamber Aluminum profile , filled with polyurethane. Back thermal isolation is stone wool density 40 kg /m3

Werner collector has very small thermal loses.
