Product feature :
1 Coating time is the most important part of solar vacuum tubes, our product coating time for more than an hour, membrane layer thickness, high absorptivity. We use a vacuum magnetron sputtering film coating, it's advantage is the whole surface is evenly sputtering, improve the coating quality, make the film has a good selection of absorption, wear resistance, corrosion resistance sex.
2 Our products high vacuum degree, temperature of heating to 450 degrees Celsius, the air, keep out off vacuum, play a good heat preservation effect.
3 We use 304 solar spring clip next, can better support at the bottom of the tube, make the vacuum tube solar long service life. Our sealing even, no bubble, which uses a long time, also won't make internal and external pipe fall off. Make us the life span of the vacuum tube for as long as 15 years.
4 Our raw materials with 3.3 high-borosilicate glass which can resist impact from hail up to 30mm in diameter, high transmittance, heat-proof impinge good, optical strong stability
