BTE Large-scale Solar Thermal Collector
Large-scale Solar Thermal Collector: Solar local and district heat can largely contribute to the energy revolution just like solar process heating and solar cooling. In order to meet this demand, we have developed the large surface collector EFPC with its elegant industry design. They are ideal for applications in the medium temperature range, such as solar district heating systems(SDH), industrial process heat, multi-family residential installations and solar cooling.

Some details:
The system integrates optimized mechanical considerations, and the bracket torque has been tested by simulation and can withstand 42-45M/S 14-level wind. The internal flow channel, reserved interfaces and original matching accessories have been designed with high pressure standardization to build high-pressure bearing capacity, with a test pressure of 16Bar, making the long-term operation and maintenance of the system safer.
