Three- Target Solar Vacuum Tube/single target solar tubes

High Quality Solar vacuumr Tube:
1.high-activity.
2.high heat conductivity.
3.high vacuum
High Quality Solar vacuum Tube:
1.high-activity: solar spectral absoprtion increased 14%,reflectance reduced by 30-40%
2.high heat conductivity:Heat-resistant 200°C or so, anti-Alpine, minus 3 °C can keep heating.
3.high vacuum:Vacuum maintained against decay, improve performance and stability,and long time warranty to 15years.
