| specifications︰ | 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 dust and sand.
2. It prevents the tube from being easily broken caused by the volume expansion when the water in tube freezes in the frigid seasons.
3.Low thermal capacity makes the tube start up quickly. Energy inside tube can be taken out within only 2 minutes under sunshine. The insulation temperature of the heat-pipe can reach 250℃. The average heat efficiency can still be more than 50% even under -50℃.
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 5?/span>0-3Pa of vacuum, so it cannot be corroded even in moist area.
6. It perfectly solve the fatal defect of the common all-glass vacuum tube solar water heater, which will not run if one of the tubes is out of work. |
