Key Advantages:
Efficient Installation: The U Pipe Solar Collector is designed for quick and easy installation, thanks to its pre-assembled modules that significantly reduce installation time.
Simplified Connection: It features a straightforward connection technology, allowing multiple collectors to be connected side by side using pre-assembled screw connections. This setup eliminates the need for additional tubing and thermal insulation.
Integrated Design: The collector comes with an integrated return pipe and boasts highly efficient thermal insulation, ensuring optimal heat retention.
Versatile Module Sizes: The manageable module sizes not only enhance performance but also facilitate a swift and hassle-free installation process.
Customizable Configuration: The flow and return pipes can be fitted on either the left or right side of the manifold, offering flexibility in system design.
Adaptable Dimensions: The collector is available in various widths and lengths, providing high flexibility to suit different installation requirements.
Easy Maintenance: The evacuated tubes can be easily replaced without any tools, making maintenance a breeze.
Product Features:
Low Pressure Loss: The design minimizes pressure loss, allowing for the connection of several modules in series without compromising performance.
Leakage Safety: With a minimal number of soldering points, the risk of leaks is significantly reduced, ensuring high reliability and durability.
Durability: The Ritter Solar tubes are renowned for their indestructibility, as proven by the hailstone test in accordance with DIN EN 12975-2.
High Energy Yield: The collector delivers a high energy yield, especially during transitional periods and in winter conditions. Even at low temperatures, it outperforms flat collectors in terms of energy output.
Minimal Heat Loss: The high vacuum within the evacuated tubes results in extremely low heat loss, maximizing energy efficiency.
