U Pipe Evacuated Tube Solar Collector

Features
1.There is no water and scaling in the vacuum tube, long-term use will not affect the heat collection efficiency.
2.Without restriction to the installing angle, this solar collector can be placed vertically or horizontally.
3.This U pipe evacuated tube solar collector can still work if one vacuum tube is damaged occasionally.
4.The evacuated tube collector uses circulating pump to force liquid to achieve heat-transfer cycle.
5.Compared to the pipe heat solar collector, this solar panel has higher heat efficiency.
6.The vacuum tubes absorb the solar energy and transfer into the heat energy, then pass it to the U-shape pipe. So it can get high temperature.
7.This U pipe evacuated tube solar collector can be combined with the architecture properly. The standard frame is suitable for pitched roof or flat roof.
8.Our U pipe vacuum tube solar collector can be used all year round in the cold climate.

Description
U pipe evacuated tube solar collector consists of U-shape water pipe, aluminum fin, vacuum tube and collector frame. This equipment has the advantages of good hot and cold water circulation as well as high heat transfer efficiency. Separated from water tank, this solar collector is used for the split solar water heaters.
U pipe is equipped with heat transfer working medium in the, and can directly absorb the heat by aluminum fin to realize circulating heat exchange. If the evacuated tube is broken, this solar collector can still operate as usual due to no water inside the tube.
U pipe evacuated tube solar collectors can be installed in parallel or in series. The working pressure of the system reach to 6 kg f/㎡. The collector tubes can be placed at any direction. After installation of the control device, the hot water system can achieve automatic operation.

Working Principle of U Type Solar Collector
The vacuum tubes absorb solar energy, and the heat energy is transferred to U pipe by an aluminum fine. The water under the effect of the circulating pump enters into the inlet pipe, and then goes into the outlet through U-shape tube, thereby taking the heat of the solar collector and depositing in the heat storage tank.

Parameters of U Pipe Evacuated Tube Solar Collector

Selection Note
1.We provide different roofing connectors for our clients to install their solar collectors on either flat roof or pitched roof.
2.Please ensure there is enough space to set up our evacuated tube collector.
3.The header frame and the U tubes are one, with large volume, there is need to use the crane when installing this U pipe evacuated tube solar collector.

Operation and Notes
1.The installation angle and position should comply with the design requirements.
2.The solar collector should be fixed with the main building structure or collector bracket to prevent slippage.
3.Leak test should be carried out when it is completely connected.
4.The U pipe evacuated tube solar collector should avoid air drying or exposure for a long time, which will affect the life span.
5.Please periodically check the pressure of the circulating fluid, if the pressure decreases obviously, check the piping and filling.
6.If the coating is shedding or the vacuum tube is broken, please replace timely.

Packaging and Transportation
1.The samples can be packaged in wooden case and cartons.
2.The U pipe evacuated tube solar collector is packed in carton or carton packing with palletizing.
3.Transport by sea.
