Product specialty: (1) High heat effectiveness:
Higher than normal all-glass tube by 10%; (2) Heat-pipe
conduction, no water inside, thus it is successfully prevented
form the defects of tube blockage and low power output caused
by water fouling and deposits or dust and sand; (3) With small
thermal capability, it can output power in 2 minutes. The
highest temperature of cooling end can reaches 250degree
centigrade. The average heat efficiency can still be 50% even
under -50 degree centigrade (4) High efficient selective
absorptive coatings and vacuum heat insulation technology
ensure the tube to get higher heat output in cloudy weather and
in moist area, especially in winter. (5) Solar collecting plate
is installed and sealed inside the tube of high-quality
borosilicate glass with 5x10-2Pa of vacuum, so it cannot be
corroded even in moist area; (6) Hot water system can endure 0.
6Pa so that it can be connected to tap
