solar evacuated tube



Solar-product YYJ-SVT-01


1) Reliable and efficient twin-glass solar tubes;
2) Copper heat pipes for rapid heat transfer;
3) Easy plug-in installation;
4) Free maintenance;
5) Suitable for mains pressure water (up to-1.0 bar);
6) Corrosion resistant silver brazed copper header;
7) Aluminum frame;
8) Powder coated (black, brown or silver) aluminum casing;
9) Stable solar conversion during the day;
10) The perfect solar collector for domestic solar water heater systems;
11) Ideal for commercial solar water heating applications.

Work Principle:
1) The operation of the solar collector is very simple.
2) Solar absorption: solar radiation is absorbed by the solar tubes and converted into heat.
3) Solar heat transfer: heat pipes conduct the heat from within the solar tube up to the header pipe
4) Solar energy storage: water is circulated through the header, via intermittent pump cycling.Each time the water circulates through the header, the temperatures is raised by 5-10oC. Throughout the day, the water in the tank is gradually heated.
