Dürr’s EcoQPower reduces energy consumption in paint shops by 21%

The mechanical and plant engineering company Dürr has developed a sustainable energy management system for automotive paint shops that can reduce both energy requirements and CO2 emissions by around 20%.

The intelligent EcoQPower system links all energy flows in the painting process and enables excess heat and cold to be used elsewhere for heating or cooling. Dürr is currently building a paint shop optimized with EcoQPower for a German automobile manufacturer. It is the first paint shop to comply with EU Taxonomy requirements.


The sustainable EcoQPower system links all energy flows in the painting process and makes it possible to use excess heat and cold elsewhere.

The Fraunhofer Institute for Building Physics IBP in Stuttgart has analyzed the effect of EcoQPower on the carbon footprint of paint shops. Two identical paint shop concepts were compared—one with and one without EcoQPower and each with all-electric operation using a conventional electricity mix. The result: EcoQPower reduces CO2 emissions by 19.2% over the entire life cycle of the paint shop, i.e. from production (including material transport) to recycling at the end of use.

The utilization phase is particularly important: Thanks to EcoQPower, 21% less energy is needed in the painting process because the energy used is utilized much more efficiently. At the heart of the combined heating and cooling system realized with EcoQPower are heat pumps, water circuits, and intelligent software.

The study of the Fraunhofer Institute shows: Energy-optimized operation of paint shops with EcoQPower improves not only the carbon footprint but also the economic efficiency. With a utilization period of 15 years and 110,000 painted cars per year, plant operators save costs in the seven-figure range yearly thanks to the 21% reduction in energy consumption.

The Dürr paint shop equipped with EcoQPower also meets the demanding EU Taxonomy requirements. The taxonomy is a central element of the Green Deal, with which the European Union wants to accelerate the climate-friendly restructuring of the economy. The regulations serve to classify sustainable investments that support climate and environmental protection.
