Type:Metal Glass Solar Heat Tube
Structurer:Single glass tube vacuum inside
Working angle against sun:27~38 Deg.
Working pressure:6.0 bar
1).This is Full Vacuum Tube with Direct Flow Pipe.
2).High heat efficiency, 15% higher efficiency than normal vacuum tube.
3).The direct flow pipe is made up by two concentric single-wall-tubes.
4).Cold water follows through the inner tube from upside down and flows out to the collector from the bottom through the space between the inner & outer tube,
taking the heat made by the absorber
5).It could be installed at any angle, even horizontally, while normally heat pipe tube should be installed at 30°-90°
