Salient Characteristic：

【1】Use main material: Germany imported high efficient selective blue titanium absorber,

high density heat insulation cotton, high purity copper tube, super white cloth grain toughened

 glass and soon.

【2】Use the most advanced the whole plate laser welding process for copper and absorber,

which has advantages of solder joints evenly, welding strength good, no damage and small

resistance of hot transfer coating.

【3】Use the overall pressure riveting process(not play rivet process) for aluminum alloy frame

 and back plate ,strengthening the four corners with aluminum soldering. The back plate is smooth,

level off and has good sealing low heat loss, besides, no deformation under the1000 kg dead load.

【4】 Unique design for frame 、mound layer、sealing material, so solar collectorhas good sealing、

no water mist, droplet which ensures collector’s absorption efficiency and service life;Strong loading

 capacity, collector has no leakage under 1.5Mpa pressure.

【5】Use flat plate solar collector in warmer climates will have best efficiency.
