5 years international responsibility for vacuum tube solar air collector and 15 years for glass vacuum tubes due to original quality problems.


Working Theory and Parts Description:

VISION VAC series vacuum tube solar air heating collector is one of the most economical collector with pretty high efficiency in solar air heating, it is usually be used in active open loop circulation system for direct solar air heating.


Solar vacuum tube together with inside stainless tube are plug directly into manifold tank, when cold air in evacuated tubes is heated with solar irradiation, in an active open loop solar air heating system, the hotter air in vacuum tube will be blow out and pumped to area where the hot air is needed, and the same time circulate colder air into vacuum tube for another solar hot air circulation.


Features of VISION Vacuum Tube Solar Air Collector:

1. Most economical and practical collector for solar air heating;

2. Wide applications for hot air heating, space heating, etc;

3. Large heating capacity from 100 to 100,000 square meters;

4. Efficient direct hot air heating with big flow air circulation;

5. Strong adaptability to flat or slope roof or wall 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.

9. Works much efficient in subzero weather condition.

10. With little heat loss dure to high vacuum insulation tubes;

11. Technical support is available with VSION SOLAR.


Advantages of VISION Vacuum Tube Solar Air Collector:


Comparing with flat plate solar air collector:

1. Much more economical for hot air heating application;

2. Much higher efficiency and lower heat loss with vacuum insulation;

3. Much more efficient to freezing weather condition;

4. More convenient in system parts carring and installation;
