Profile: Jiaxing Jinyi Solar Energy Technology Co.,Ltd. is engaged in the production of solar water heaters and solar collectors. Our solar energy central water heating system constitutes a solar collector, a tank, a controller system, an electromagnetic valve, a circulating pump, and appurtenances. These collectors make the cold water to become warm and then circulate it to the tank with the help of a circulating pump. Our U type solar collectors are designed in such a way that the vacuum tubes absorb the solar energy and transfer it into the heat energy, and then pass it to the U pipe. Thus it gets high temperature. There is no water collected in the vacuum tube, so that the tube does not break in winter. It is combined with a perfect architecture and has a standard frame that is suitable for pitched roof/flat roof. It is combined with the existing pipeline. Our heat pipe vacuum tube is hollow with the space inside evacuated, which is same as the solar tube. The heat pipes used in solar collectors have a boiling point of only 30° and if it is heated further, the water can be vaporized.
