U Pipe Solar Collector

详情

Characteristics
The U type solar collector are always connected with existing heating supply device. The selective coating of the evacuated tube converts solar energy into heat energy and transfers heat to metal U tube by the aluminum fin.The liquid (usually glycol-water antifreeze mixture) in the metal U tube is heater, and conducts the heat energy to the water inside the storage tank through plate exchanger or internal spiral coiler.
