Three Target Solar Vacuum Tube

We are instrumental in providing to our valuable customers excellent quality Three Target Solar Vacuum Tube which is available with following specification:-
1.Absorptivity: >0.93
2.Emittance: <6.5%
3.Average heat loss: <0.65
4.Hail resistance: 25 mm
5.Vacuum degree: <0.005 Pa

Technology specialty:
The tube has two technology patents in solar energy utilization.
1) The first patent technology: Glass-metal heat envelopment craftwork.
2) The second patent technology: Exhausting set for SHCMV tube.
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 reach 250 degree 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. 6MPa so that it can be connected to tap water tube..
