Junkers, a brand of Bosch Thermotechnology is rounding off its range of solar products by presenting a new generation of vacuum tube collectors and adding one model to its family of flat collectors.
With regard to the vacuum tube collectors, the former VK 180 models will be replaced by the VK 140-1, the VK 280-1 and the VK 230-1. This means that Junkers no longer offers only one, but a total of three versions for different uses: the VK 140-1 has six tubes and is the smallest collector of the new series with 1.43 square metres. With twelve tubes, the VK 280-1 collects solar energy on an area of 2.82 square metres. The VK 230-1 with 21 tubes on an area of only 2.32 square metres is particularly compact. It can be installed horizontally or vertically and it is particulary suited for commercial buildings and multi-family houses.
Completely closed double wall glass tubes and a highly selective coating make the new vacuum tube collectors particularly sturdy and efficient. The models VK 140-1 and VK 280-1 additionally feature CPC technology (Compound Parabolic Concentrator) for maximum solar gain. A coated CPC aluminium mirror behind the tubes directs the sun-rays onto the absorber pipes in order to achieve the best possible performance irrespective of different angles of incidence and diffuse light. New flat collector with attractive price-performance ratio The family of flat collectors from Junkers has gotten bigger, too. The new starter collector FCC expands the Junkers range to three models. The compact collector has a particularly attractive price-performance ratio. With a height of 2044 mm and a width of 1050 mm, it is convenient and compact. An aluminium frame, special solar safety glass and reinforced corners give the solar module the stability required. Thanks to safe and stable plug-in connections, installation and connection are quite easy.
All Junkers solar collectors are certificied to Solar Keymark (EN 12975), a European quality label for solar collectors.
