Tecnocanto pyrolytic cleaning ovens are design for removing plastic from metal parts, using a thermal cleaning under vacuum. The pyrolysis process is carried out controlling the temperature along a preset time. The working temperature is between 350-500ºC and the cleaning cycle time is from 2 to 6 hours, depending the type of polymer and contamination, their quantity and the total weight of the metal part. All these setpoints are controlled by a PLC and managed from a touchscreen easy user interface. Since the cleaning process is made under vacuum, there is no fire or any burn of the plastics and contamination, eliminating the risk of chemical oxidation / corrosion of the metal part to be cleaned.
