The new EcoCDuty large-chamber solvent-based cleaning machine can be run with hydrocarbons or modified alcohols. Operating under full vacuum, the EcoC Duty has a work chamber designed for loads measuring up to 1,250 x 840 x 970 mm and weighing up to 1 metric ton.
To match the cleaning task, EcoCDuty is available as a steam degreaser with vacuum drying as standard but can also be ordered with one or two additional flood tanks.
Heat-treating contractors, metalforming 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 a solvent-based cleaning system, the large-chamber EcoCDuty. This machine is designed for loads measuring up to 1,250 x 840 x 970 mm and weighing up to 1 metric ton. "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," said a company spokesperson.
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 aluminum 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.
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 stabilized solvents following oil compatibility testing. Moreover, the unit is suitable for cleaning off sulphur-containing oils.
To ensure a high cleaning quality, the EcoCDuty is provided with a new pre-degreasing feature using steam. This technology directs the oil-laden solvent straight into the distillation circuit, thus minimizing oil enrichment of the solvent and oil deposits in the flood tank. This is made possible by a powerful distillation system capable of handling as much as 400 or even 500 liters/hour, depending on the solvent employed. The oil collected by distillation is automatically removed via the standard oil discharge system that has a capacity of four liters per hour. Customers who encounter high oil input rates can add a second unit, thus doubling the capacity of the distillation system to eight liters per hour. To remove particulate contaminants from the solvent as well, the distillation system is preceded by a filter unit with bag or cartridge filters.
On EcoCDuty versions with a flood tank, powerful frequency-controlled pumps ensure quick flooding and draining of the work chamber and tank. Furthermore, these versions comprise a separate filter circuit for each tank. Full-flow filtration of the solvent is provided in the supply and return flow lines by means of three filter units per flood tank. These can be fitted with bag or cartridge filters.
The EcoCDuty is designed with a new 7" color display with self-explanatory pictographs that make the cleaning system safe and quick to operate. The stainless steel flood tanks have a smooth surface and come without internal heating components. This design prevents the formation of chip and dirt pockets that could re-contaminate the parts. Customers who do not yet own a steam heating source can order an optional external steam generator to heat the distillation unit. The flood tanks are heated exclusively by waste heat from the distillation system, i.e., no additional energy input is necessary.
When it comes to part feeding, depending on the equipment configuration, it can be loaded manually using a pallet truck or forklift. Moreover, custom loading solutions ranging from semi-automatic single-station to fully automatic multi-station systems are supported as well.
Large maintenance openings offer an additional advantage, as they provide fast access to all service-related components.
To protect the system from dirt and heat in harsh production conditions, a roof with internal ventilation is available.
