18 vacuumTubes Solar Collectors

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 sand.

2.It prevent the tube from being easily broken caused by the volume expansion when the water in tube freezea in frigid season.

3.  The liquid (usually a glycol-water antifreeze mixture) ) in the heat pipe heats up, and conducts the heat energy to the water inside the storage tank through plate exchanger or internal spiral coils.

4.  Start up quickly.Energy inside the tube can be broken out within 2 minutes under sunshine.

5.  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.

6.  It perfectly solves the fetal defect of the common all-glass vacuum tube solar water heater,which can’t run if one of the tubes is out of work.

7.  It is widely used in large-sized hot water project,sea water desalination,industrial heating,heating system and other fields.
