Cleaning process overview

12

 111 Melting phase

After heating up the cleanable parts under vacuum most of the polymer drips off into the separator.

 2

22 Pyrolysis phase

Polymer that did not drip off during the first phase will be pyrolyzed under vacuum. The resulting gases are converted to carbon dioxide and water vapor in the catalyst converter.

 3

33 Oxidation phase

Polymer residues that still exist after the pyrolysis phase will be burnt by controlled air supply. During this phase the exhaust gases also are converted in the catalyst.
