Solvent-based cleaning system allows ultrasonic and filtration simultaneously

July 29, 2014

Dürr Ecoclean offers the EcoCCore system for solvent-based parts cleaning, designed for operations with nonhalogenated hydrocarbons or modified alcohols under full vacuum conditions. Standard equipment includes two flood tanks, heat recovery, and full-flow plus bypass filtration capabilities.

With the new preliminary vapor degreasing process, the oil-containing distillate is not passed into the flood tank but directed straight into the distilling system. This minimizes oil deposits in the flood tank and an undesirable contamination of the solvent with oil. The result is a degreasing action that is suitable for parts to be coated or laser-welded after cleaning.

The system also allows the use of ultrasonic and filtration simultaneously. Particles are discharged throughout the process cycle. Pumps equipped with variable-frequency drive units control the volumetric flow rate. The unit comes with a frequency-controlled rotary drive for rotation and high-accuracy positioning of parts, states the company. A gentle operating mode prevents sensitive parts from getting dropped or displaced during start-up or handling operations.
