We offer our customers not only high end, powerful collectors but resistance to hailstorms.
The frequency and intensity of storms increases more and more. Especially storm, heavy rain fall and hail may
cause major damage to houses and installed systems. The collectors have undergone a special stress test by
TÜV Rheinland to make our customers feel more relaxed about the issue of hailstorms. According to this hail
test (hail resistance class 4) the collectors and especially the tubes have been shot with 40 mm ice balls
and a speed of 100 km/h.
So far, the collectors had to withstand 25 mm ice balls and a speed of 83 km/h.
This test was filmed by a high speed camera.
