Detailed Product Description

Working principle of vacuum tube solar collector (SPU):

In each vacuum tube there is a U pipe with direct flow-through that is connected to the header pipe inside manifold. This U pipe is seamed in an aluminum heat transfer fin in the interior of vacuum tube that transmits the heat from the interior tube to the U pipe.

Solar radiation permeates the outer glass tube and is captured on the outside of inner glass tube by highly selective sputter layer. The captured solar radiation is transmitted to flush-contact aluminum sheild and then copper pipe filled with heat transfer fluid. The 360°aluminum heat transfer fin assures the fastest energy transfer.

Each vacuum tube solar collector is individually tested for leakage and other defects. Anodized aluminum case and frame ensure no corrosion will happen to vacuum tube solar collector.

Advantages:

1. No efficiency decrease during service life time

2. No external pipe lines

3. One-side in-/outlet and hence only one roof penetration

4. Best possible insulation

5. Anodized aluminum casing and frame and anti corrosion

6. Angle adjustable frame

7. Pre-assembled unit and no tube assembling is necessary

8. Ideal for both flat roof and inclined roof

9. Pre-assembled packing

10. Operate with water pressure up to 8 bar.
