BG best tri-element vacuum tube
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.
