Detailed Product Description

Working principle of solar U pipe collector:

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