Filderstadt/Germany, July 2014 –( ASIA TODAY )– With its EcoCWave, Dürr Ecoclean has developed an innovative equipment system for aqueous cleaning processes which can handle a wide range of tasks – from coarse to fine cleaning – in an efficient manner. To this end, the new all-round talent comes with a list of features which ensure superior cleaning quality and process reliability, shorter idling times, and major energy savings. Moreover, this flexible machine sets standards in terms of space demand, operator-friendliness and design.
Aqueous part cleaning with alkaline, neutral or acidic media ranks among the most widely employed technologies in many industries, e.g., automotive manufacturing and its tiered suppliers, medical equipment production, mechanical workshops performing machining, punching, drawing or bending tasks, precision mechanics and optical systems. Application levels range from coarse to intermediate and, ultimately, fine cleaning. Dürr Ecoclean's new EcoCWave system, superseding the existing Universal 81W line, covers this entire application spectrum thanks to its modular, forward-looking technology. With its very small footprint the system can easily be integrated in any production process. It also provides versatility, being easily adaptable to changing cleanliness and throughput specifications so that the user will enjoy investment certainty.
Intelligent technology yields superior cleaning quality
The EcoCWave is equipped with two or three flooding tanks, depending on customer specifications. The tanks exhibit a flow-optimized rounded geometry and are of upright design. Unlike the low-mounted rectangular containers used in conventional aqueous cleaning equipment, the round tanks prevent the formation of chip and dirt traps. Improved cleaning quality and a longer service life of the cleaning fluid are the result. Moreover, each tank has its own separate fluid circuit comprising full-flow filtration. The cleaning and rinsing fluid is filtered on filling and draining as well as in the bypass. Bag filters or cartridge filters can be fitted in a combination-type filter housing. The system's filtration characteristics can thus be adapted to changing cleanliness requirements quickly and without any hardware modifications.
Another contributor to improved performance is the optimized rollover unit in the working chamber. It ensures that the fluid and mechanical cleaning devices – e.g., ultrasonic units and spraying nozzles – can reach the product effectively from all sides. In addition, the design of the rollover unit minimizes fluid drag-out.
Faster processes cut per-unit costs
Powerful pumps and large-diameter piping used throughout the EcoCWave accelerate the operations of filling and draining the work chamber and tanks. As a result, non-productive times are minimized, product throughput is increased and per-unit cleaning costs are reduced. These improvements benefit spray cleaning processes as well. Here, an increased number of nozzles working in optimized arrays deliver a more effective cleaning performance and hence, shorter cycle times even in removing coarse contamination. In order to shorten cycles still further, the vacuum drying system available in addition to hot-air drying has also been improved.
Equal to any cleaning task
Due to the use of variable-frequency driven pumps, volumetric flow rates can be adjusted precisely as needed. Major energy savings are achievable as a result. On the other hand, the cleaning process can be selectively adapted to meet specific requirements. Thus, different work chamber filling levels may be defined in immersion processes, e.g., with filling and draining cycles suitable for cleaning parts having blind holes or complex geometries. An intense fluid exchange in critical component areas substantially boosts the system's cleaning performance. In spraying processes, the jet strength can be adapted exactly to the part being processed. Moreover, the ability to control the spraying pressure expands the range of cleaning agents that can be used.
Continuous reconditioning of the rinsing fluid is provided by an Aquaclean system which can be integrated into the machine. The cleaning fluid in the first flooding tank is heated entirely by waste heat from the evaporation process.
Flexibility includes adaptable batch volume
The EcoCWave has a vacuum-tight work chamber designed for batches measuring up to 670 x 480 x 300 mm. As an alternative, an enlarged work chamber for 670 x 480 x 400 mm containers may be installed without enlarging the footprint. The volume adapted batch configuration reduced per-unit costs.
Easy operation with process visualization
A new colour display with self-explanatory pictographs makes the EcoCWave easy, fast and reliable to operate. Diverse process data such as the work chamber fluid level are indicated in real time by the built-in process visualization system. An acquisition of all relevant process parameters (e.g., for the development of cleaning programs) can be implemented optionally.
Exterior design: space-saving and open to modification
Apart from its high performance, Dürr Ecoclean's engineers focused their attention on minimizing the system's footprint. Accordingly, a machine configured with two flooding tanks needs only 1.8 sq.m. of floorspace. The EcoCWave features a stylish appearance with integrated loading system and all-round safety-glazed enclosure.
