U pipe solar collector
1.twin-glass evacuated tubes：Reliable, efficient, High temperature resistant
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 90 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.
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.
