Red copper full-surface absorber plated with blue titanium and quartz. The absorber is imported from Tinox, Germany. By using a kind of special-designed physical sedimentation way (PVD), the coating is plated on the red copper continuously. Under vacuum environment, titanium is gasified by the effect of electron beam, causing chemical reaction when nitrogen and oxygen is added and forms N-doped titanium dioxides. Then it sedimentates and condenses on the red copper. Moreover, after gasified by electron beam, quartz forms an emissive layer on surface, which could protect the coating effectively.

A) Key Material---High efficient solar absorber with blue titanium coating imported from Germany. (Thanks for the professional supplier-Tinox)

Advantages of Tinox absorber:

High absorptance: 95%
Low Emissivity: 4%
Copper Full Surface, hence heat transfer efficiency would be better.
Long Lifespan: Absorber efficiency could last 25 years.

B) Ultrasonic whole-plate welding machine imported from USA.

We are the first manufacturer using ultrasonic whole-plate welding technology in China, which makes the flat plate solar collector more beautiful, efficient and duruable.

Advantages of ultrasonic welding:

Surface preparation is not critical.

No defects are produced from gases and filler metals.
Dissimilar metals having vastly different melting points can be joined.

Minimum surface deformation results.

Very thin materials can be welded.

Because of the low temperatures that are involved, the characteristics of the materials are not altered and are continued through the weld zone. Moreover, heat-affected zone is minimized.

The equipment is simple and reliable and only moderate skill is required of the operator.
