Solar Vacuum Tubes

Features of Solar Evacuated Tubes
1.The solar vacuum tube is a breakthrough in the efficiency of hot water production for residential and commercial uses. The tubes collect the sunlight during the day and they also can produce hot water even on cloudy days.
2.The solar vacuum tubes can perform well in cold weather conditions. That’s because the evacuated tube solar collectors can easily attain high temperatures. Additionally, they can collect and retain heat even in cold weather, and due to their incidence angle modifier they can gather solar energy evenly throughout the day.
3.There is a small amount of glycol inside the solar evacuated tube, it helps to achieve latent vaporization and make the tubes produce about 40% more hot water than a flat plate collector.

Description
The solar vacuum tubes can be divided into glass absorber vacuum tube (known as all-glass vacuum tube) and metal absorber evacuated tube (or called glass-metal vacuum tube). The heat pipe evacuated tube is composed of heat pipe, absorber, glass tubes and metal end cap. Solar evacuated tube is the core component of the solar water heater, and is honored as the heart of the solar water heating system.

Structure of Solar Vacuum Tubes
The structure is similar to the inside of an elongated thermos. There is a vacuum between the inner and outer layers. On the surface of the inner glass tube is coated with spectral selective absorbing coating, which is used to maximize the absorption of solar radiation.
The structure of the solar evacuated tube consists of inner glass tube, selective absorbing coating, vacuum interlayer, support (spring clip) and getter.

Advantages of our Company
