In many industrial cleaning applications the use of solvents yields valuable process advantages. Committed to making optimum use of these benefits, Dürr Ecoclean keeps refining and improving its equipment portfolio continually to adapt each cleaning system perfectly to its task and enhance the cost efficiency, process reliability and sustainability of the solvent-based cleaning process.
Organic solvents are commonly used in industrial part and surface cleaning where highly oil-contaminated or difficult-to-dry parts are involved, or where oils are used in machining and metal forming operations or oil-free surfaces are specified for downstream steps such as, e.g., hardening. The cost efficiency, process reliability and eco-friendliness of such cleaning is chiefly a function of the equipment technology employed.
Short cycles due to minimization of non-productive times For maximum cleaning efficiency even when working to exacting cleanliness standards, Ecoclean systems afford a high vacuum performance and are equipped with strong pumps and large-diameter piping. These design details permit rapid filling and draining of the work chamber and tanks while also ensuring an optimum solvent supply to the product basket.
Multi-stage cleaning Validated processes – e.g., in the medical field – and applications calling for oil-free surfaces in downstream steps such as hardening, CVD/PVD coating, brazing, welding or adhesive bonding will often impose the need for ultra-fine cleaning. To this end, the solvent cleaning systems can be fitted with several tanks and flooding tanks for a multi-stage cleaning process. A key contributor to the high cleaning quality attained is the standard bypass filtration system which recirculates the cleaning fluid up to 100 times per hour.
Consistently engineered to save energy The solvent-based part cleaning equipment from Dürr also provides advantages in terms of energy use. Thus, the first flooding tank is heated entirely with waste heat recovered from the distillation module. Up to 20 per cent electrical energy can be saved via the intelligent equipment control system tailored to the customer’s specific production cycle.
