The tube structure is between all-glass evacuated tube and metal-glass evacuated tube with heat pipes.

All-glass Evacuated Solar Collector Tube with Heat Pipe for Solar Collector(Solar water heater)

Features:

1) The tube structure is between all-glass evacuated tube and metal-glass evacuated tube with heat pipes

2) Suitable for frigid zones because there is no water in the tube

3) Designed for pressure system

4) Heat pipe material: TP2 copper

5) The heat collecting part is a vacuum glass tube that lowers heat loss

6) Stable solar conversion throughout the day, with the round shaped tube allowing solar penetration from all angles
