Product Description

1.twin-glass evacuated tubes：Reliable, efficient, High temperature resistant
anti-freezing.
2.There is no water in the vacuum tube, it can still work even one tube is broken.
3. U pipe, most efficient
4.aluminum alloy manifold and bracket, corrosion resistance, easy to install. It can be installed both on flat roof and inclined roof
5.more flexible Installation, installation angle from 0 degrees to *0 degrees, roof and wall hanging installation.
6.high temperature resistant rock wool / glass cotton insulating layer, high density, good thermal insulation properties.
7.high quality copper heat exchanger, it can withstand 1MPa.
8.Improves the environment and save your fuel cost.
working principle: 
the vacuum tube absorbs solar radiation and transform into heat, pass to the fin by the tube wall, and then transfer to the U pipe by the fin, U pipe absorbs heat then transfer to medium, cold medium continuously flow into inlet and heated by U pipe, then flow out  from the outlet, so that obtain the heat of solar energy heating water.
