Durr Ecoclean offers its EcoCFlex 3 cleaning machine that replaces the standard six-axis jointed-arm robot with a Scara manipulator to withstand tougher conditions in robot cleaning cells for pre- and final cleaning of powertrain parts. The Scara handling system is made of high-strength aluminum and stainless steel and needs neither paintwork nor a protective suit. It is resistant to high-pressure water jets and to immersion and can withstand booth temperatures as high as 65°C (149°F). Cleaning chemicals may range from 6 to 10 pH with no effect on the system. Besides solving environment issues, the machine addresses control issues by using one joint CNC control unit for the Scara manipulator and the cleaning machine that replaces the separate programmable logic controller and robot controller.

The machine’s other features contribute to performance. A water knife directs the water jet in a focused pattern onto the areas to be cleaned, unlike a conventional round nozzle. The machine is set up so that it can perform both high- and low-pressure treatments in addition to injection flood washing in one station. Other features combine for quieter operation and reduced idle times. In conjunction with the modular vestibule design, it is possible to obtain “on-spec” cleaning results in cycles starting from as little as 30 sec., according to the company.

Operating at 30 kWh, the machine offers efficiency and sustainability. Energy consumption can be logged per cycle, per shift or per hour using an optional energy monitoring system, promoting accuracy in cost estimation per part. Further contributing to energy efficiency is the EcoCDry system vacuum dryer which uses no upstream compressed air blow-off stage, which uses 65 percent less energy than a vacuum dryer with upstream air blowing, according to the company.
