Evacuated heat pipe technology
The evacuated tubes utilize the thermos flask principle, comprising two glass tubes with an evacuated gap to prevent heat loss.
The inner glass tubes feature a highly selective absorber layer (AI/ALN), ensuring optimal energy yield.
An aluminium heat transfer plate facilitates an efficient heat transfer medium system.
Copper heat pipes effectively transfer the extracted heat.
The manifold is insulated with rock wool and an aluminium lamination to minimize heat loss.
The flow and return connections utilize compression ring fittings (Ø 22 mm), ensuring secure and easy installation of the pipework.
The commonly used working fluid is water, suitable for operating temperatures ranging from -30 °C to 90 °C.
Heat pipes made in China
The evacuated heat pipe technology uses the maximum fraction of solar irradiation at minimum ambient temperatures of -30 °C and maximum operating temperatures to 90 °C.
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 temperatues.*
- Well-known indestructibility of the evacuated heat pipe collectors according to DIN EN 12975-2.
Recommended application areas:
Hot water generation and heating support.
*in dependence on the respective heat transfer medium.
Product Characteristics
The collectors are fully pre-assembled, resulting in short installation times.
The modules have manageable sizes, allowing for high performance and quick, easy installation.
The thermal insulation is highly efficient.
The manifold allows for filling the flow and return pipes on either the left or right side.
The collectors come in different widths and lengths, providing high flexibility.
The system can operate in both pressurized and non-pressurized modes.
The system can operate independently of the season, depending on the heat transfer medium.
The thermal conductivity is rapid.
The evacuated tubes have a high vacuum, resulting in a high energy yield and low heat loss.
The system can operate in temperatures as low as -30 °C and as high as 90 °C.
The two-loop system ensures good water quality and prevents freezing on cold days. It also allows for easy integration with other energy sources.
