high efficiency three target solar vacuum tube
Heat pipe solar vacuum tube
Primary advantage: 1) Competitive price on same quality level2) Prompt delivery 3) Environmental protection
Features:
1) Super conductive liquid in copper heated pipe
2) Widely used for pressurized solar water heaters and solar projects
3) Can be used in cold weather of -40°C
4) When one vacuum tube is broken, the system still can work as normal.This doesn't effect the whole system.
Components:
all-glass double-tube co-axial vacuum tube, alluminum fins, silicon gasket, copper heat pipe
