Yaoguo Solar *8 ***0mm solar vacuum tubes for solar collectors



 Solar vacuum tube is the core component of solar water heater and solar hot water project and heating engineering. Its performance determines the quality of solar heat utilization. Yaoguo Solar Thermal company introduced domestic advanced automated connecting tail machine, automatic eyelet machine, automatic washing machine, automatic drying machine and the latest magnetron sputtering technology production line designed by Tsinghua University, to ensure the quality of coating, and make the thermal efficiency improved by more than *2%.Through strict control of vacuum technology, we can ensure the high heat efficiency and anti-attenuation performance of the solar evacuated tubes. Because of the advanced equipments and strict management, various types of vacuum tubes produced by Yaoguo have the characteristics of high temperature resistance, cold resistance, fast heating and so on.

Yaoguo Solar has a complete industrial chain of solar vacuum tube, which ensures the quality and quantity of the goods. Solar borosilicate vacuum tube is a kind of high-precision products. So all the procedures finishing in one place could produce items with stable quality, and reduce cost at maximum to benefit the customers.



Rounding head: Using the automatic round equipment to foam a round shaped appearance with stable quality.

Connecting tail: Using the fully automatic connecting tail equipment to make it in one-step foaming.

Cleaning:  By using the automatic cleaning and drying machine, tubes have high cleanliness, no scratches, no remaining drops of water in a greatly shorten drying time.

Coating: Coating with a fully automatic three target magnetron sputtering coating machine, and the coating film is not aging and anti attenuation.

Sealing: The semi-automatic horizontal sealing machine could reduce scratches. Tubes are with Stress stability and beautiful nozzle.

Exhausting air: Using automatic exhausting machine to evacuate the tube at **0 degrees Celsius high temperature could ensure good heat insulation performance.

Baking: By using the heating equipment, we could completely pump out the air to achieve the complete vacuum state.

Detection: Detecting heat absorption and emission rate of the coating film, and simulating the anti-strike capability of the evacuated tubes.
