Detailed Product Description

Three target vacuum tube solar collector has property and spec.as following:

1.  All-glass double-tube co-axial structure, high borosilicate 3.3 glass ;

2. Transmission Ratio of the Outer Glass Tube.

3.  Structure: Cu/SS-ALN(H)/SS-ALN(L)/ALN.

4.  Sediment method: 3 target magnertron sputtering plating ;

Comparing to Al-N-Al vacuum tube, it has advantages in cold area as following:

a.      Absorbance: 12% higher.

b.      Emission Ration: 30-49% lower.

c.      In alpine area, copper ions emission ration is lower than that of aluminum ion. So it could work properly even circumstance temp. is lower than -30Deg C.

d.      Stainless steel ion has performance of high temp. resistant, anti-stagnation temp. coating will not decay or get aging or disappears.
