Product Description

Heat Pipe Solar Collector Work Principle:

1. Solar absorption: solar radiation is absorbed by the evacuated tube and
converted into heat
2. Solar heat transfer: Heat pipes conduct the heat from vacuum tube inside to header
tank of solar collector.                                                                                                                                                       
3. Solar energy storage: water or other liquid is circulated through the header tank,
via intermittent pump cycling.                                                                                                                                                 
4. Circulation between solar collector and storage tank: each time the water or other liquid
circulates through the header tank, the temperature is raised by 5-10°C, the water in the
storage tank is heated gradually by this way.

Advantages and benefits
- Short installation times due to complete pre-assembled collectors.
- Manageable module sizes for a very high performance and a quick and easy installation. 
- Flow and return pipes may be filled on the left or the right side of the manifold.
- High flexibility due to the different widths and lengths of the collectors.
- Pressurized and non-pressurized operation.
- Season independent operation depending on the heat transfer medium.
- Rapid thermal conductivity.
- High energy yield and low heat loss due to the high vacuum of the evacuated tubes.
- Operating at minimum ambient temperatures of -30 °C to maximum operating temperatures of 90 °C.
- Two loop system to constantly maintain a good water quality and to ensure water on cold days due to the anti-freezing medium in the solar circulation loop and an easy integration of other energy supplies.

High Efficiency Vacuum Tube Heat Pipe Solar Collector 

1. European Solar Keymark certified heat pipe solar collector.

2. Brazil Inmetro certified heat pipe solar collector. 

3. High efficiency of 74.5%. 

4. High annual energy yield with 1808kwh each year for the 1820 heat pipe solar collector. 

Key benefits:
- High collector efficiency of medium temperature suitable for pressurized and non-pressurized solar thermal applications.
- Due to the rapid heat conductivity evacuated heat pipe collectors are suitable for solar thermal applications in cooler areas with low ambient temperatures.*
- Well-known indestructibility of the evacuated heat pipe collectors according to DIN EN 12975-2.
