Hydrocarbon system for inline, individual part cleaning in cycles

of up to 370 x 220 x 200mm (L x W x H). The maximum weight of parts or batches is 30kg. This allows the new inline cleaning system to reach throughput of 2.7 tons per hour. With dimensions of 7500 x 3500 x 3100mm, it more than meets the demand for space-saving cleaning technology. The EcoCSpeed’s flexible design makes it possible to equip the system with additional process modules to ensure that the overall 40-second cycle time is maintained. The work chambers are loaded in a delayed process by a handling system which is tailored to the workpiece or the batch. In the work chambers, the parts are treated by injection flood washing (IFW), steam scouring and vacuum drying. For IFW, jet systems pump the cleaning agent at high pressure into a flooded work chamber, producing a whirlpool effect. Due to the vacuum drying process, workpieces leave the system completely dry and ready for immediate downstream processing.

Dürr Ecoclean GmbH, Germany, has introduced the EcoCSpeed for inline cleaning of individual parts. This innovative system makes it possible to clean complex geometrical workpieces during the manufacturing cycle using non-halogenated hydrocarbon. The EcoCSpeed has several process modules that can be loaded in delayed phases via a specially designed handling system. The cleaning process may include injection flood washing, steam scouring,  The EcoCSpeed is used for inline cleaning of individual parts

and vacuum drying, and the cycle time can be adjusted to suit the manufacturing cycle. Cleanliness is achieved even for stringent specifications. Process quality and efficiency is ensured by cleaning complex parts individually rather than in batches. In the past, short cycle times and strict cleanliness requirements presented problems for inline cleaning processes, especially when cleaning complex, mass- produced workpieces. Very complex, continuous systems were required, and the spraying methods used in these systems were only partially able to clean the parts. The innovative EcoCSpeed system, which is equipped with several process modules, was designed to be integrated into production lines, or directly connected to production systems and machining centres. The workpieces can be cleaned individually or as a batch from production in a product carrier. The basic version of the EcoCSpeed is equipped with five process modules, which are designed for part/batch dimensions
