A new perspective for sustainable painting
March 2012 – The Dürr Eco+Paintshop stands for a paint shop that lowers energy and materials consumption as well as reducing emissions. The cooperation agreement between Dürr and Industrial Solar GmbH of Freiburg, Germany, a supplier of innovative, high performance collectors for solar energy, clearly fits into this concept very well.
Industrial Solar GmbH (ISG) specializes in the development, production and marketing of Fresnel solar collectors as generators of industrial process heat. The compact, low-maintenance Fresnel collectors concentrate sunlight and thus function very efficiently. Especially in countries having direct natural irradiance of more than 1500 kWh/m² annually, the potential for solar thermal generated process heat is huge. The energy won can be utilized in numerous ways within production processes.
For Dürr and its energy-optimized Eco+Paintshop ISG is the ideal partner. With ISG’s high performance collectors, Dürr is able to generate process heat of up to 400°C. Particularly in the operation of ovens, which require temperatures of up to 220°C, large savings can be made. At sunny paint shop locations, such as Tangier, Morocco, for example, approximately 30% to 50% of the energy required for the ovens can be gained from solar energy. A significant reduction in CO2 emissions of up to 1,000 tons annually contributes to low emission production. At the same time non-renewable resources are conserved. There are other benefits too: as the solar collectors reflect the sun’s rays, the paint shop does not heat up so much – this means that the plant operator needs less energy for cooling.
Dürr’s Eco+Paintshop places sustainability and environmental awareness firmly in the centre stage. In addition to the utilization of well-proven technologies, such as the EcoDryScrubber dry paint separation system and the rotational dip process, Ecopaint RoDip, solar process heat generation with the aid of high performance collectors represents yet another step towards improved ecological efficiency.
