Specifications
CE cetificationthree-high magnetron sputtering technique
Borosilicate 3.3 glass
thinkness :1.6mm
SS-ALNx/Cu coating
Each solar evacuated glass tube consists of two layers of borosilicate glass which is strong enough to withstand high temperature and high pressure and has high sunlight transparancy.
The inner tube(absorber) is coated with copper,aluminum and stainless steel in an entire enviironment of nitrogen. This type of selective coating(SS-AlN/Cu) is able to withstand high temperature and the absorption efficiency can reach 0.95.
The closed end of the inner tube is fixed into the outer tube and is supported by a spring holder. The other end is sealed together with the outer tube.
The gas between the inner tube and the outer tube is evacuated in high temperature to form a vacuum which works as supperior insullation to protect the heat energy absorbed from losing. So the heat loss of the tube can be as low as 0.4w/(m²·°c)
Solar evacuated glass tube is able to work effectively even in cloudy and tough weather. Evacuated glass tube based solar collector is fast replacing flat plate type solar collector. Our vision is to make the best evacuated glass tube for the sake of our clients and a clean world. The evacuated glass tubes we are supplying include:
Model 58mm×1500mm
Model 58mm×1600mm
Model 58mm×1800mm
Model 58mm×2000mm
Model 58mm×2100mm
