“AURON” is a direct flow-through vacuum tube collector with a newly developed and designed mounting concept. The design of the mounting elements is based on careful studies of the steps involved in the installation process. The individual modules can be joined seamlessly without any gaps to create an optically harmonious solution that allows virtually shadow-free installation in horizontal or vertical orientation, on flat or sloped roofs or even on facades. A special tube thread connector means that the metal/glass connection is not under any load, thereby ensuring a long service life for the vacuum tubes. The sum of the parts is what makes this design so effective.
