Key Points
* Excellent performance evacuated tube collectors
* Can be mounted free-standing or on a pitched roof, easy to install, simple roof fixings
* Integrated into building perfectly, any angle installation
* U pipe - offer low maintenance
* No water in the Vacuum Tubes, no freezing problem in winter, can be used in cold area. It can be still operate in the event of occasional tube breakages.
* 3 years warranty, 20+ years lifespan
* Market leading efficiency/output
* Aluminum frame, strong structure, light weight.
* Outstanding Germen design
* High and constant pressure of polyurethane foaming technology ensure the outstanding insulation quality.
The vacuum tube collector with CPC (Compound Parabolic Concentrator) reflector has high energy yield due to special collector structufe that contains vacuum tubes with highly selective absorber layer, U shap copper pipes inside vacuum tubes for heat transport, aluminum heat transfer fin and highly reflecting CPC reflector. The CPC reflector ensures that direct and diffuse sunlight will fall onto the absober inside of tubes, enve at the back of tubes. The CPC reflector can improve collector efficiency by 15%.
For water, space and process heating and solar cooling.
Scope of Delivery
Fully pre-assembled unit comprising
- 6, 12, 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.
