Working Theory and Parts Description
The Manifold Vacuum Tube Non-pressure Solar Collector is one of the most economical collector with pretty high efficiency in solar water heating, it is usually be used in active open loop circulation system for direct solar water heating.
Solar vacuum tubes are plug directly inside manifold tank, when cold water in evacuated tubes is heated with solar irradiation.
As the specific gravity of hot water and cold water are different, hotter water goes upward to manifold tank and colder water goes downward to glass vacuum tubes.
Through this continuous circulation, the cold water in manifold tank will be gradually heated, in an active open-loop solar system, the hotter water in manifold will be pumped to hot water storage tank, and the same time circulate colder tank water to manifold collector for solar heating.
Features of Vacuum Tube Solar Collector
1. Most economical and practical collector for solar water heating;
2. Wide applications for hot water heating, pool heating, space heating, etc;
3. Large heating capacity from 500 to 500,000 Liter hot water;
4. Efficient direct hot water heating with big flow water circulation;
5. Strong adaptability to flat or slope roof installation;
6. Easy installation and connection with simple structure design;
7. Much safe and stable after system installation and commissioning;
8. Applicable to active open loop circulation system or passive thermosiphon system.
9. With anti-freezing protection it works well in subzero weather condition.
10. With technical support from VISION company, your system seldom has problems of breaking tubes, broken or deflated manifolds and storage tank.
