Energy-sacing Solar vacuum tube

Energy-sacing Solar vacuum tube:
good material;high thermal efficiency;small heat lose;long life;strength;crossion;anti-code.
Solar vacuum tube:
Basic features:
1. selection: 3.3 high borosilicate glass as raw material, its performance in line with ISO3585: 1991 requirements.
2. thermal efficiency: use of space technology, 8-layer vacuum coating, vacuum layer of pure unadulterated, high vacuum and durable, the sun has a very high absorption rate and low thermal emittance.
3. heat loss is small: between the layers in the vacuum tube to maintain a high vacuum, to minimize heat conduction, convection heat loss.
4. Long life: the coating layer performance and stability, not aging, fading, material selection, production, transportation, quality and other aspects of procedure strictly, longer life.
5. Corrosion: The new anti-corrosion technology, effectively inhibit microbial growth, excellent resistance to chemical attack, for a variety of water quality.
