Tried and tested technology
Even the smallest ray of sunlight reaches the absorber via the mirrors behind the tubes. Therefore even when diagonal radiation occurs, the vacuum collector still achieves constantly high solar earnings and energy yields.
auroTHERM exclusive collectors are manufactured using toughened glass and have a glass vacuum seal for longevity. The tubes are internally coated with an aluminium nitride absorber for maximum solar efficiency.
Each collectors is delivered with 6 (VTK 570) or 12 (VTK 1140) tubes per collector. They can easily be fitted in series if required to maximum 7 VTK 1140 in one row. The appealing design of the Vaillant mounting brackets create a neat and attractive installation.
