A) High heat effectiveness: Higher than all - glass evacuated solar collector Tube by 15%
B) Heat pipe conduction: Successfully prevents the defects of tube breakage and low power
output caused by water fouling and deposits or dust and sand.
C) Prevents the tube from being easily broken caused by volume expansion when water
freezes in the frigid season
D) Low thermal capacity makes the tube start up quickly
E) Energy output within only 2 minutes of sunshine
F) Insulation temperature can reach 250 degrees centigrade, average heat efficiency can still
be more than 50% even under -50 degrees centigrade.
G) 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
H) Solar collecting plate is sealed inside a high quality borosilicate glass tubeWith 5 x 10 -
3pa of vacuum, to stop corrosion; .
