Solar hot water energy
Our company produces have used the high strength, good heat resistance high silicon very hard glass production of glass vacuum heat-collecting tube, layer between the vacuum tube appearance, sedimentary selective A1-N/A1 absorbing materials, the absorption of as much as 93% of the sun, inside and outside of the vacuum less than 5 * 10-3 PA and can withstand 0.6 eat Cmpa empty temperature of 230 degrees Celsius above bask, with excellent collection hot performance and good insulation performance. To make sure there are good heat preservation effect, the heat exchanger choose SUS304 stainless steel production, anti-corrosion, not deformation, thermal insulation layer advanced overall foaming technology.

Working Principle
Solar vacuum tube was evacuated into the tank; The coating inside of tube can absorb more than 92% heat energy from sunshine. The cold water in water tank flows into the tube and become hot, because of different density between cold and hot water, there will be a natural circulation in the tube, and hot water will float back to tank. 50 mm thickness heat insulation layer by polyurethane between inner tank and outer tank can keep the temperature of hot water for about 2 days without any sunshine, consumer can enjoy comfortable bathe anytime.
