Solar collector The characteristic: 1 the vacuum tubes absorb the solar energy and transfer into the heat energy, then pass it to the u pipe, it can get high temperature. 2 there is no water in the vacuum tube, so the tube will not break in the winter. 3 it is steady and credible. 4 it can be combined with the architecture perfectly. 5 it can be combined with existing pipeline. 6 it can still operate in the event of occasional tube breakages. The details of material: Outer tank: alnico 1.5mm Manifold: 22mm thickness 2mm U copper type: 8mm thickness 0.6mm G.W. 50.6kg
