Working principle:

1. The high weather-proof selective absorbing film from full-automatic magnetron sputtering production line developed by Bontel;
2. With Bonding heat transferring technology and laser welding technology;
3. High quality low-iron tempered glass with surface treatment to get high transmittance and low emittance;
4. Circulation fluid in closed copper pipes, no glass tubes. So collectors without corrosion and circulation fluid leaking;
5. The solid built-in absorber plate can absorb all solar radiation improve working efficiency and integrated well with buildings.
