This is Full Vacuum Tube with Heat Pipe. The absorber flat plate catches the sunshine and transfer the heat directly to the heat pipe.

Then the heat pipe transfers the heat to the condenser above, making heat exchange with the water in the collector.

The system is easy to install. No water flows inside the tube, which makes the system remains workable if one tube breaks.

Product Details:

• Special Welding process between glasses and metal. New Technology

• High heat effectiveness: Higher than normal all-glass tube by 10%

• With small thermal capability, it can output power in 2 minutes. The highest
  temperature of cooling end can reach 250 degree centigrade. The average heat efficiency can still be 50% even under -50 degree C

• Available size: 70x 1900mm,10 or 20 tubes per collector

• 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.
