Vacuum tube

The evacuated tube is a product with improved geometry and performance. Two concentric glass tubes are closed on one side, forming a hemisphere, and fused and hermetically sealed with each other on the other side (evacuated insulation).

To use solar energy, the internal glass tube is coated with an environmentally friendly, highly absorbing layer on the outside, thus turning it into an absorber. The coating is protected in the evacuated space. The aluminium nitrite sputter coating used is characterized by extremely low emission and excellent absorption.
