ule EcoEMOS Energy. This tool facilitates the systematic recording and evaluation of consumption values. For instance, individual consumption places can be optimized, and superfluous ones can be identified and eliminated. In combination with the working time model saved in EcoEMOS, a systematic and automated reduction of consumers in production-free times can be realized. With this new module, Dürr with their long-standing experience offer very practical possibilities for the energy-conscious and environmentally friendly system operation in an energy-intensive environment.

Clear recording of energy consumption data with EcoEMOS.

Dürr Builds Energy-efficient Green Paintshop
with Integrated Paint Process for BMW

In recent news, Dürr inked a deal to construct its Green Paintshop for the BMW Brilliance Automotive Ltd. joint venture in Shenyang, China. The automobile paintshop incorporates Dürr's latest technologies and is to consume less than 500 kilowatt-hours of energy per car body. That is a third of the level customary ten years ago. BMW Brilliance intends to build an environment-friendly automobile paintshop in Shenyang. Among other things, the plant will use the EcoDryScrubber spray booth system, which enables energy consumption per booth to be reduced by up to 60 percent. At the base paint stage, the RoDip M rotary dip-coating process saves energy and chemicals through shorter tanks. Another "green" feature is the so-called Integrated Paint Process, which dispenses with the filler coat application and subsequent drying phase. Thirty-two Dürr painting robots are being installed for automated paint application. They are equipped with the latest atomizer generation EcoBell3 and the EcoLCC color changer. This product combination minimizes paint loss on color changes and shortens the painting process. Other measures for conserving resources include heat recovery through heat wheels, waste-heat boilers and the use of a special membrane for reducing water consumption.

With new painting installations, so-called greenfield proj-
ects, a conclusive concept saving energy and resources is cer-
tainly easier to realize. Old installations in particular, however,
also offer very great optimization potentials when looking
more closely. For this, Dürr offers an assessment that is car-
ried out by designated experts with a long-standing experience
and extensive process know-how. The investigations may be
adjusted to the most different aspects. According to customer
preference, attention is focused on energy and material effi-
ciency, on capacity adaptations, on increase in availability, on
optimum conversion of legal specifications or on quality im-
provement. This way, an existing painting installation can be
made fit again with a manageable investment.
