Dürr is installing an Eco+Paintshop for Shanghai General Motors designed for reduced energy consumption and lower emissions. The new shop will have a throughput of 20 bodies per hour but can be extended to double capacity.
The facility will use fully automated paint application for both interior and exterior coating, from the primer to the base coat through to the clear coat, thereby reducing paint consumption. The primer is applied by 20 EcoRP L133 and L030 EcoRP painting robots, while base and clear coats are applied by 44 paint robots in stop-and-go operation. All robots are equipped with the EcoBell2 paint atomizer. Before painting, the bodies are prepared and cleaned by an ionization portal and the EcoClean exterior cleaning system.
The paint shop also will use Dürr’s EcoDryScrubber, where dry separation of paint overspray with extensive air recirculation is designed to reduce energy consumption in the spray booth. This technology also does not use water or chemicals. Adding to the shops energy efficiency is heat recovery from the spray booth exhaust air and the oven’s exhaust air streams. Dürr’s optimized hall ventilation concept also helps this process.
