Solar Thermal Collector

How does a solar collector work？

Vacuum tubes absorbs sunshine from the sun

Vacuum tube transfers heat energy to heat pipe

Fluid goes through copper ,and then be warmed by the heat pipe which connected with copper. 

The glass wool insulation prevent heat loss.

Features

Pressurized operation and no water flow in the vacuum tube, so water scale and tube exposition are avoided.

It can be integrated with the architecture perfectly and be connected with the existing pipes.

Interferential film coated vacuum tube with absorptance among 94% to 96%, and vacuum degree of 5×10-4 pa; its service life will be not less than 15 years.

Heat pipe collectors have passed the the Solar Keymark certificate and CE certificate, met EN12975 standard.
