Product Description

Vacuum Pyrolysis Oven is designed specially for cleaning polymers from a variety of metal parts. The parts to be cleaned are heated in a chamber where the polymer melts and drains into the bottom collector. Remaining polymer is vaporized and then water scrubbed in a secondary scrubber where condensates are collected and rush out with water. Since cleaning takes place under vacuum, combustion does not occur. The parts are protected from excessive or localized high temperatures. The whole process has no pollution.

► APPLICATIONS

Note: Custom sizes are available per request.

► CLEANING PROCESS

I. Melting Phase

The parts to be cleaned are heated to 320°C in the  chamber. After this process, most  of the polymer melts and drains into the bottom collector.

 

 

II. Pyrolysis Phase

Polymer that did not melt during the first phase will be pyrolyzed and vaporized under vacuum. The generated gases are converted to CO2 and H2O (Vapor) in the catalyst heater.

 

 

III. Oxidation Phase

Remaining ploymer that still exist after the pyrolysis phase will be burnt under vacuum and limited air. The generated gases also are converted in the catalyst.
