1, Vacuum tube is consists of two layer of glass tubes2, ISO900:2000, CE certificate;3, 0.91 transmittance of outer tube.4, The outer tube is made of extremely strong transparent quartz sand which can resist impact from hail up to 25mm in diameter.5, The inner tube is also made of quartz sand, but it is coated with a special selective coating with strong heat absorption and lowest heat loss.6, The air is evacuated from the space between the two glass tubes to form a vacuum, so it eliminates heat loss.7, This why the tubes are able to absorb the energy from infrared rays which can pass through clouds.8, So it also can operate in low temperature and low sunlight medium.
solar vacuum tube Excellent resistance,corrosion keeping water clean Excellent performance of absorbing high efficiency
We adopted adanced Nanometer Technolgy. Vacuum tube Nanometer molecular engineering is applied to greatly improve the absorption function, the heat collecting ability increase 18%, the water temperatu
