Services offered

GREENoneTEC manufactures large-size collectors in the GK 3003 series with a standard size of 8 and 13 m², single & double glazed. A special design of the absorber and the attractive performance data make these collectors ideal for large solar thermal systems working at higher temperature. The optimized mounting system, which permits time-saving installation by crane, and hydraulic connection considerably reduce the overall time and effort required to install the system.
