Solar collector plays an important role in solar heating system. U pipe vacuum tube collector performs better for its low heat loss, high adaptability and aging-resistant property.

Features:

The collector is composed of vaccum tubes , manifold case, U pipes, tailstocks and frame.However, collector could not work independently, but should be operated together with other professional water heating system.
Heat is transmitted to heat storage water tank from collector to produce hot water.

1. No water flows in the vacuum tube, so water scale and tube exposition are avoided. Single broken tube will not affect the working of the system.
2. It can be integrated with the architecture perfectly and be connected with the existing pipes.
3. Interferential film coated vacuum tube has the absorptance among 94% to 96% and vacuum degree of 5¡Á10^-4 Mpa; its service life will be not less than 15 years.
4. U pipe collectors have passed the Solar Keymark certificate and CE certificate, met EN12975 standard.

Working Principle:

Vacuum tubes absorb and convert the sunlight into heat energy which will be transferred to U pipe by fins. Then, it heats the medium in the U pipe. By the circulation of the medium between U pipe and water tank , the cold water is heated.
