Product Description

Solar vacuum tube, is the main component of solar water heaters. it is similar to a conventional Dewar flash and consisit of two borosilicate galss tubes with high chemical and thermal shock resisitance. The outer side of the inner tube is coated with a sputtered solar selective surface. The coated inner tube is closed at one end and sealed at the other end to the outer tube.

The annular space between the outer tube and inner tube is evacuated to virtually eliminate heat loss by conduction and convection.

Why Choose Us

(1)Full automatic solar vacuum tube production line and advanced & strict testing processing guarantee the entire quality stability.(2)Vacuum degree can reach to 10-4 Pa which effectively reduces the heat loss rate of 0.03-0.06.

(3)Apply metallic copper as bottom metal layer, which is super strong in sbsorbing and possessing extra low heat loss. The heat loss rate is 50% lower than ordinary vacuum vacuum tubes which ULT ≤0.5W/(W/(M2.℃).

(4)Excellent insulation. The stagnation temperature higher than 270℃.

(5)Patent technology breaks the limitation of graded coating, an enable its working temperature from -40℃ to 40℃.

(6)Huge production capacity. 5 full automatic production lines accompany with production capacity of 100000 pcs solar vacuum tubes per day.
