U tube solar collector

The U tube solar collector is a kind of highly efficient direct flow heat transferring collector that detaches the hot from cold liquid pipeline. The selective coating on the inner tube of the evacuated tube converts solar energy into heat energy and transfers heat to copper U tube by aluminum fins. Thus the liquid (normally a glycol-water antifreeze mixture) in the metal U tube is heated, and conducts the heat energy to the water in the storage tank through plate exchanger or internal spiral coli.
Features:
1. Unique structure contributes the high heat transfer efficiency
2. Suitable for pressurized water heater system (up to 0.8Mpa)
3. Freezing resistance: -35℃
4. Reliable and durab
