4. Relevant copper parts for connection.

Feature:

1. Perfectly concordant with the architecture appearance.

2. Solar collector can be installed on roof, balcony or wall of flat, sloping or vertical sides.

And the storage tank can be installed in room instead of being exposed outdoors.

3. Anti-freezing, more suitable in cold areas, Fast start up on cloudy or rainy weather.

4. Water does not flow in vacuum tubes, that preventing the collectors from freezing and bursting in cold climate. Realize hot water available for all year around in cold areas.

5. No water inside vacuum tubes, breakage of some tubes will not inflence the ordinary operation of the whole system.

6. Equipped with electric heater, working station, completely automatic cooperation.

7. Whenever you need hot water regardless of time and weather.

8. Equipped with magnesium bar what improves the water quality and lengthens the lifespan of the storage tank.

9. It can produce hot water with constant temperature.

10.Indirect solar system enable water quality to be much cleaner than direct solar system.

8. Time of uploading water is cut, 24 hours water supply on condition that pipeline is working.

9. Life duration: 15 years, warranty: 5 years

10. CE, ISO9001, CCC,EN12975 approved

11. Lead time: 5-7 days for a 20ft container, 10-15 days for a 40ft container

12. OEM,ODM offered.

13. To serve Europe, America, Africa clients better, at work in Europe work time

Detailed Specifications:

Expansion vessel

Closed-loop systems require a expansion vessel, an expansion vessel has a vessel in which air is locked inside a bladder or diaphragm. It screws into standard 1/2 inch or 3/4 inch threaded plumbing fittings. When pipes are filled with heat transfer fluid (water and glycol ),and the operating pressure of the system is set, the fluid will occupy a given volume on the temperature. As the fluid is heated by sunshine, it expands. This is why the expansion vessel is necessary. The expansion vessel allows the fluid to safely expand by compressing the air in the chamber.

Working temperature: -10 to 99 degree centigrade

Max working pressure: 10 bar

Solar collector

The heat pipe solar collector are connected with existing water heating device. The selective coating on the inner cover of vacuum tube absorbs solar energy and transfer heat to heat pipe by aluminium fins, the medium in heat pipe changes into air and rise to condenser. Then heat pass through heat exchanger and meanwhile, vapour becomes liquid and go back to bottom of heat pipe. Continuous water heating in pipeline is based on the circulation of this heat transfer process.

1. The perfect combination of vacuum tube and heat pipe makes higher heat efficiency: heat pipes quick transfering capability, vacuum tubes selective absorb coating and heat preservation integrate that makes them superior heat performance.

2. Wide applicable range: as the heat pipe has less heating space for medium, it can function quickly even on cloudy day. It can work normally even in -40degree centigrade. As no water flows in vacuum tube, it can avoid frost cracking or scaling which influence heat efficiency.

3. Each individual tube can work independently, and the whole system can keep working if individual tube is broken. The lifespan of heat pipe vacuum tube is over 15 years.

4. The unique connection design of heat pipe and vacuum tube can ensure seal tightness and tube replacement convenience.
