Sell Conductive Evacuated Solar Collector Tube

Features:1) High heat effectiveness: higher than all glass evacuated solar collector tube by 15%2) Heat pipe conduction: successfully prevents the defects of tube breakage and low power output caused by water fouling and deposits or dust and sand3) Prevents the tube from being easily broken caused by volume expansion when water freezes in the frigid season4) Low thermal capacity makes the tube start up quickly5) Energy output within only 2 minutes of sunshine6) Insulation temperature can reach 250
