Product specialties:
1. High heat effectivness: higher than normal all glass tube by 10%

2. Heat pipe conduction, no water inside, thus it is successfully prevented from
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 reaches 250 degrees, the average heat efficiency can
still be 50% even under -50 degrees,it is also ideal for hot climates and other bad condition(such as acid ,windy,rainy and so on) .

4. High efficient selective absorptive coating 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 the high-quality
borosilicate glass with 5 x 10-3 Pa of vacuum, so it can not be corroded even
in moist area

6. Hot water system can endure 0.6Pa so that it can be connected to tap water tub

Features :
Vacuum tubes assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high borosilicate glass, gradual change of SS-C/CU selective complex absorptive coating and these make vacuum tubes have high performance of absorptance and low reflection ratio. Through the interlayer, vacuum has a unique effect of thermo, with its tempurature up to 380 degrees of idle sunning, performing a strong heating ability.
