Features:
1) High heat effectiveness: higher than all-glass evacuated solar collector
tube by 15%
2) Heat pipe conduction: successfully prevents defects of tube breakage
and low power output caused by water fouling and deposits or dust and
sand
3) Prevents tube from being easy breaking caused by volume expansion
when water freezes in frigid season
4) Low thermal capacity makes the tube start up quickly
5) Energy output within only 2 minutes of sunshine
6) Insulation temperature can reach 250°C, average heat efficiency can
still be more than 50%; even under -50
oC
7) High efficient selective absorptive coatings and vacuum heat insulation
technology ensure the tube has higher heat output in cloudy weather and
in moist areas, especially in winter
8) Solar collecting plate is sealed inside a high quality borosilicate glass tube
with 5 x 10
-3pa of vacuum, to stop corrosion; even in moist
conditions
