Aqueous parts cleaning with alkaline, neutral or acidic media ranks among the most widely used technologies in many industries.

The new EcoCWave system from Dürr Ecoclean (www.durr-ecoclean.com) supersedes the company’s existing Universal 81W line and covers a wide application spectrum, thanks to its modular construction.

It also features a compact footprint, allowing the system to be easily integrated in production processes.

The EcoCWave is equipped with two or three flooding tanks (depending on customer specification) that feature a flow-optimised rounded geometry designed to 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, allowing the system’s filtration characteristics to be adapted to changing cleanliness requirements quickly and without any hardware modifications.

Also featured is a rollover unit in the working chamber, to ensure that the fluid and mechanical cleaning devices (ultrasonic units and spraying nozzles) can reach the product effectively from all sides.

Powerful pumps and large-diameter piping throughout the EcoCWave minimise filling and draining times; they also help to increase product throughput and cut per-unit cleaning costs; and to further shorten cycle times, the vacuum drying system — available in addition to hot-air drying — has also been improved.

Furthermore, the use of variable-frequency driven pumps allows volumetric flow rates to be adjusted precisely as needed, while 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).
