EcoCDuty by Dürr Ecoclean – an innovative modular solvent-based cleaning system for heavy loads
  Heat-treating contractors, metal forming shops and companies from the automotive and aircraft industries in particular require cost-efficient part cleaning and degreasing equipment capable of handling high capacities. Addressing this demand, Dürr Ecoclean has developed an innovative solvent-based cleaning system, the large-chamber EcoCDuty. This machine is designed for loads measuring up to 1250 x 840 x 970 mm and weighing up to 1 tonne. Operating with hydrocarbons or modified alcohols, it provides high cleaning quality and process reliability at fast cycle times. Additional benefits of this modular unit include its exceptional ease of operation and attractive design.
Heat-treating shops must clean workpieces in large quantities, both before heating and after quenching in oil. With punched and shaped parts leaving the press at just a few second intervals, the part cleaning process must not slow down production. In the automotive industry, suspension components and other aluminium and steel items must have a (laser-) weldable surface. In aircraft manufacturing, honeycomb parts, shaped components and pipes impose high demands on the equipment due to their dimensions and specified cleaning results. Although products differ, the demands on the cleaning system are the same. It must provide enhanced capacity, process reliability, cost and energy efficiency, and speed. Over and above these properties, high availability, ease of maintenance, eco-friendliness, favourable investment costs and short delivery times are important. In developing the new EcoCDuty engineers therefore focused on these criteria. This large-chamber cleaning machine built by Dürr Ecoclean uses hydrocarbons or polar solvents (modified alcohols) and operates under full vacuum. Its modular design ensures adaptability to individual user needs. Configured as a steam degreaser in its standard version, the system is additionally available with one or two stainless steel flood tanks – e.g., for a process comprising steam degreasing and injection flood washing or steam degreasing, injection flood washing plus a preserving step. Vacuum drying is standard on all three versions. Chlorinated metalworking fluids can be effectively removed by means of appropriately stabilised solvents following oil compatibility testing. Moreover, the unit is perfectly suitable for cleaning off sulphur-containing oils.
