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.red copper Heat pipe, φ14x70 condensor,one-way transferring, fast heat transfer speed, less heat loss, low temperature resistance, it can be used in -35 degrees.
4.aluminum alloy manifold and bracket, corrosion resistance, easy to install. It can be installed both on flat roof and inclined roof
5.high temperature resistant rock wool / glass cotton insulating layer, high density, good therma
