glass evacuated tube with new design
Characteristics
1) using copper as the bottom metal layer , lower emittance ,high thermal efficiency.
2) Adopting stainless hydronium in the place of aluminium,high temperature resistance .
3) The cover rate of selective absorber coating is high, the effect of decalescence and reataining hot is good.
4) The effect of super-anti-cold is superb, it can run uner **0 centigrade.
