For water and space heating.
Scope of Delivery
Fully pre-assembled unit comprising
- evacuated tubes based on the thermos flask principle
- manifold with direct flow heat conduction unit and dry tube connection
Collectors are packed in individual boxes. In addition, there is a sun protection sheet over the evacuated tubes.
Installation types
- Pitched roof, flat roof, horizontal
Advantages and benefits
- Specially developed for applications that require horizontally mounting.
- Short installation times due to complete pre-assembled collectors.
- Simple and reliable connection technology in order to extend several collectors side by side through pre-assembled screw connections. Further tubing and an extensive thermal insulation is not necessary
- Integrated return pipe and highly efficient thermal insulation.
- Manageable module sizes for a very high performance and a quick and easy installation.
- Flow and return pipes may be fitted on the left or the right side of the manifold.
- High flexibility due to the different widths and lengths of the collectors.
- Quick and easy exchange of the evacuated tubes without using any tools.
Product Characteristics
1. Low pressure loss allows several modules to be connected in series
2. Minimum of soldering points ensures a high leakage safety
3. Well-known indestructibility of Ritter Solar tubes confirmed by the hailstone test DIN EN 12975-2
4. High energy yield in the transitional period and winter
5. In wintery conditions with a 400 W/m² irradiation and 0 °C air temperature at a temperature of 20 °C, Ritter Solar evacuated tube collectors already have a higher energy yield than flat collectors.
6. Extremely low heat loss due to the high vacuum.
