Product Description

Scope of Delivery

Fully pre-assembled unit comprising

- 6, 9, 12, 15 or 18 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.
