Detailed Product Description

The new evacuated heat-pipe tube is a revolutionary breakthrough in solar thermal
technology as well as the symbol of a great leap in solar thermal utilization field
after mankind's continuous researches year after year. The tube has the following
advantages:1) Heat-pipe conduction, no water inside, thus it is successfully prevented from
the defects of tube block and low power output caused by water fouling and deposits of mud and sand2) It prevents the tube from being easily broken caused by the volume expansion
when the water in tube freezes in frigid season3) Start up quickly. Energy inside the tube can be taken out within 2 minutes under
sunshine. The stagnation temperature of the heat-pipe can reach 220℃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 winter5) Solar collecting plate is installed and sealed inside the tube of high-quality
borosilicate glass with 5x10-3Pa of vacuum, so it cannot be corroded event in moist area6) It perfectly solves the fetal defect of the common all-glass vacuum tube solar water heater, which can not run if one of the tubes is out of workalign=baseline border=0>
