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
Durable U Pipe Solar Collector
● 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
● 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.
