Specification

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

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

4)Heat pipe material: TP2 copper.

3)Designed for pressure system.

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.

Features

This type of tube has good reputation in Europe and Asia countries.
