    NTG expands production capacity
    Work has recently begun on the new approx. 400 sqm assembly hall. As an extension to the existing assembly hall, the new building serves the purpose of achieving a complete separation between contract manufacturing parts and systems or components for our high-tech applications.
    NTG thus meets the increased requirements of our customers in the field of high vacuum technology with regard to the cleanliness of assembly surfaces.
    In connection with the new construction of the assembly hall there is also an extensive conversion of the existing assembly hall. The sealing of the hall floor as well as the integration of a clean room and the installation of an interferometer should be mentioned here.
    NTG is thus setting the course for a successful future in economically difficult times.

    203,73 KWp – Photovoltaic plant
    At the beginning of October 2007, extensive renovation work began on the NTG main building. As the existing roof did not meet NTG’s thermal or ecological requirements, the existing Eternit roof was replaced by roof elements with an integrated insulation layer.

    In the course of these renovation measures, a photovoltaic system was installed at the same time. 1116 solar modules with a total output of 203.73 KWp are working on a roof area of almost 2500qm. The plant is to generate 185000 KWh of electricity in the year. This corresponds to the annual demand of approx. 50 average households.

    With an annual carbon dioxide saving of almost 100 tons, we are making an active contribution to climate protection. For us, this investment also means a clear commitment to the Gelnhausen-Hailer site. We do not follow the general trend of relocating production to Eastern Europe or Asia, but will continue to pursue the goal of developing and manufacturing high technology in the Main-Kinzig district.

    The plant has been in operation since 11 December 2008. You will soon be able to view the yield of the plant on our homepage. On 31.03.2009 the 1000kWh limit was exceeded for the first time and the previous peak value of 1022kWh was reached.
