Product Description

Product Description

The evacuated tubes consists of two concentric glass tubes which are sealed in a semi-circular shape on one side and are joined to one another on the other side. The space between the tubes is evacuated and hermetically sealed (evacuated insulation). To use solar energy, the internal glass tube is coated with an environmentally friendly, highly selective layer on the outside, thus turning it into an absorber. The selective coating is protected in the evacuated space. The aluminum nitride sputter coating used is characterized by an extremely low emission and a high absorption rate.
