Solar vacuum tube / solar glass tube the perfect combination of the glass vacuum tube and the copper heat pipe makes the longue solar Heat-pipe Vacuum Tube.
1. Higher heat efficiency: advanced heat transferring style of the heat pipe, excellent selective absorb coating and reliable vacuum heat preservation make it of higher heat output performance.
2. Wide applicable range: as the heat pipe has less heat capacity, it can be started quickly even under cloudy day and collect heat effectively. It can work normally even -30 below degree. As no water in the vacuum tube, it can effectively prevent from frost cracking or scaling.
3. Each individual tube can work independently, and the whole machine could still work even if one tube were damaged. The service life of the heat pipe can be longer than 15 years.
The unique connection between the heat pipe and the vacuum tube ensures both sealing and replacement of the damaged glass vacuum tubes.
