Address:2 Fl, Sci & Tech Building, No. 168, Xueqian Road, Wuxi, Jiangsu, China Zip:214001
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.
