Application area:

Good solution for areas where people have demand for god water quality

For cold area, people have a large demand for hot water

Places where is daily needs of hot water

Features:

1. It can withstand pressure of tap water when it works. And copper coil in tank bear pressure Storage tank is used to heat water flowing through copper coil .water absorbs much heat when flowing through copper coil, hot water is available immediately when you need.
2. High quality SUS304-2B stainless steel for water tank, processed y argon arc welding technique, under strict quality control system. tank will never rust and leak.
3. High borosilicate all glass vacuum tube has selective absorbing surface, absorptivity above 0.93 and emissivity below 0.05.it enables vacuum tube to have god absorb and transmit performance.Relevant accessories are optional instead of compulsory. Client can choose some of none according to actual need
4. It can produce hot water with constant temperature
5. Its indirect solar system. So water quality is superior, much cleaner than direct solar system
6. Time of uploading water is cut. 24 hours water supply on condition that pipeline is working
7. Life duration: 15 years
8. Lead time: 10-15days for a full container.
9. OEM offered

Working principle:

The water in water tank is for heat preservation and circulation, the vacuum tube collector absorbs heat then transfer to the cold water ,so that temperature raise up ceaselessly, due to the original feature of the copper coil. The water temperature of the outlet is close to the water temperature of water tank (difference within 3 degree centigrade).therefore, cold water flow via copper coil and absorbs much heat. when water flow pass outlet. then temperature is usually hot enough to use.
