Warwick, 24 February 2026 – With the EcoAUC2, Dürr is bringing a control unit with key enhancements to market. More available colours, additional functions and, for the first time, the ability to control cleaning equipment for different applicators, make the control system the central component for reliable and efficient painting processes.
In many production environments, control units need to be precisely tailored to the dosing technology and applicator to ensure reliable operation of the overall system. With the new EcoAUC2, Dürr is raising the performance of application control to a new level and, at the same time, simplifying its integration into modern plant concepts. The control of various technical components has been extended and now includes an integrated high-speed unloader, which improves cycle times and increases safety when working with high voltage. Optionally, the control unit regulates an integrated air heater to ensure a consistently high application quality, particularly in humid and warm production environments. Additional interfaces, such as PROFINET, EtherNet/IP and DeviceNet, enable seamless data exchange and simplify the integration of the control unit into existing production and plant networks.
Integrated cleaning equipment control
The cleaning equipment for the various Dürr atomisers is now fully controlled via the EcoAUC2. This significantly reduces the integration effort, especially when safely shutting down the high voltage before the high-speed rotary atomiser EcoBell2 enters the special cleaning equipment. This function is now performed by the EcoAUC2: it automatically detects whether the applicator is de-energised, and only then enables the cleaning cycle. This avoids potentially hazardous situations.
Increased colour and hardener capacity
The control unit can now control up to 20 colours – twice as many as the predecessor model. “We are seeing a clear trend towards personalisation in many applications, which is why we doubled the colour selection during the development process,” says Stephan Voigt, product engineer at Dürr. In addition, the EcoAUC2 now supports up to five hardener components, instead of the previous three. This means that infrequent but complex paint formulations are now also possible.
Ready to start without delay, intuitive to operate
The EcoAUC2 components are compactly housed in a control cabinet. Integrated in this cabinet are the process controller, the compressed air control system, the visualisation system and the interfaces for robot control and the safety PLC. Like its predecessor model, the EcoAUC2 is also fully embedded in Dürr’s ready2integrate concept. This works according to the plug-and-play principle familiar from computers: the pre-tested, certified unit is tailored to the respective dosing and application technology and can be started up on site in the shortest possible time without any additional adaptation. An intuitive visualisation system with an oversized display simplifies process monitoring and operation. The EcoAUC2 thus significantly extends the possibilities of automated application technology – for anyone who wants flexible, reliable and versatile coating in an industrial environment.
Dürr will be presenting the new EcoAUC2 for the first time at the PaintExpo in Karlsruhe (Hall 3, Booth 3320) in a live demonstration. Further information on processes, system innovations, and complementary solutions can be found in the current Dürr catalogue for industrial painting technology.
