Washing and cleaning for technical cleanliness

If residues remain on workpiece surfaces, they can have a strong influence on the result of a heat treatment and even affect the function of the heat treatment system. By washing and cleaning the parts in our modern hydrocarbon plants before the heat treatment, we avoid these possible negative effects. On the heat treatment systems, the washing process is carried out in aqueous cleaning baths with one- or multi-stage immersion cleaning with steam degreasing and hot air drying.

With final cleaning on CW systems with ultrasounic and vacuum drying, a regreasing (corrosion protection) can also be applied. During final cleaning with subsequent packaging in our clean room, we also achieve technical cleanliness to DIN 19 Level 1.
