Product Description
Scope of Delivery
Fully pre-assembled unit comprising
- 14, 18 or 21 evacuated tubes based on the thermos flask principle
- manifold with direct flow heat conduction unit and dry tube connection
- CPC-reflector
Collectors are packed in individual boxes. In addition, there is a sun protection sheet over the evacuated tubes.
Installation types
- Pitched roof, flat roof, on-wall
Advantages and benefits
- 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.
Performance characteristics
- Low pressure loss allows several modules to be connected in series
- Minimum of soldering points ensures a high leakage safety
- Well-known indestructibility of Ritter Solar tubes confirmed by the hailstone test DIN EN 12975-2
- High energy yield in the transitional period and winter
- 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.
- Extremely low heat loss due to the high vacuum.
- Outstanding design.
