Solar Vacuum Tube:
Feature
1. High thermal efficiency, more durable for low temperature and high temperature.
2. Its membrane layer at bottom is typically made of copper.
3. Absorption layer and antireflective layer is compound of Nitrogen and aluminum, adding some component of stainless steel.
4. Comparing to the general tubes, it maintains more efficient in heat preservation.
5. Meanwhile, the chemical compound in the absorption layer is more pure than normal solar vacuum tube, thus possessing the more efficient absorption rate.
