70mm There-target all glass non-pressurized evacuated tube

 

Details:

1) Unique three-layer absorption technology
2) Unique three-layer stainless steel/red copper/aluminum; heat resisting; prevents peeling off even when the glass gets waxy degeneration
3) Unique three-layer against degeneration, color fading or performance degeneration caused by empty vacuum tube overexposure to the sun, extending the useful life of the product
4) Three layer interference coating technology
5) Unique super pure copper surface - low reflection and minimal heat loss
6) Ideal heat collecting efficiency in extreme cold water; available at a temperature of -30°C
