Ecologically beneficial processes for deoiling metallic or plastic parts to be coated or brazzed gain more and more importance. Especially the low‐pressure evaporation process shows recognizable advantages. The oily parts or devices are cleaned at medium temperature and at process‐pressures of less than 0.1 mbar from the adhered machine oil. In opposite to liquid deoiling procedures also complete assembled devices can be treated in one process step only. Joined plasma processes activate or modify the surfaces for decoration or functional coatings. In the following contribution the process‐technology and machine design is explained and as an example a vacuum‐deoiling plant for automotive heat exchangers is presented.
