Good Quality Three Target Purple Golden Solar Vacuum Tube

INTRODUCTIONS                                                                                      

Three target vacuum tube has three membrane layers Cu- SS-AL. The surface color is purple golden or blue. The internal surface color is red. It has high efficiency heat. In the event of same capacity and sunshine, it can output more and hotter water than single target vacuum tube. The "three target" are high temperature resistance, high cold resistance and high heat efficiency (contrast to the single target vacuum tube ,its absorptivity has improved 5%~7%).

WORKING PRINCIPLE                                                                               

High Efficiency Solar Vacuum Tube consists of the inner and outer tubes, which are cut and coated on the condition of high temperature.

Solar Vacuum Tubes are the absorber of the solar water heater.

They absorb solar energy converting it into heat energy for use in water heating.

The hot water rise to water tank and the cool water fall to the bottom of the vacuum tube.

As the gravity theory, the hot water and cool water are continuously circulation in the vacuum tube and water tank.
