Vacuum Pyrolysis Systems: safe, gentle, efficient

VACUCLEAN is an easy to install, environmentally and user friendly vacuum pyrolysis cleaning system (vacuum cleaning oven) for removing plastic residues from tools and long components.

  • Complete removal of organic adherent matter, free from carbon residues
  • Precise, reliable and gentle cleaning of large tools and components
  • Easy installation (no gas), low operating costs
  • Increased tool life and life cycles, reduced machine downtimes

Depending on the system size, product to be cleaned and polymer VACUCLEAN removes organic adhesions within 8 to 30 hours without impacting the tools mechanically or thermally.

The cleaning process in vacuum

The fully automatic cleaning process of VACUCLEAN takes place in an electrically heated vacuum cleaning chamber. The temperature is measured directly on the product to be cleaned, which is initially heated slowly and especially easy on the material; a large part of the adherent polymers already melts now and drains off. The disintegration of the remaining polymer takes place at approx. 450 °C; the remaining carbon is finally removed by adding air (oxidation). A sophisticated sensor system controls the cleaning process preventing the development of excess temperatures at all times. Inorganic residues can be easily removed through post-treatment, e.g. with compressed air.

Vacuum Pyrolysis Systems

Through catalytic waste air cleaning VACUCLEAN produces clean air and clean waste water complying with official regulations. VACUCLEAN systems of model series 154f. may be set up and operated in Germany without an approval application because of their compact design and size.

The especially precise and gentle cleaning quality of VACUCLEAN increases the life of tools and components and reduces interruptions in production.

Compact Thermal Cleaning System

VACUCLEAN COMPACT is ideally suited for gentle and easy plastic removal from sensitive laser filters and extrusion dies.


For polymer/masterbatch manufacturers, injection moulders and plastics recyclers, there is finally a smaller VACUCLEAN cleaning system with intelligent process control:

The new VACUCLEAN COMPACT cleaning system from SCHWING features dimensions of only 2100 x 1200 x 1000 mm (HxWxD) – ideal for the smallest batches of complex tools, like expensive laser filters from recycling, screws elements from compounding extruders, pelletizing dies and nozzles. Even spinnerets and small pumps can be cleaned gently and economically. The electrically heated VACUCLEAN COMPACT thermal cleaning system is particularly suitable for:


  • Small pelletizing and extrusion dies
  • Laser filters sets for recycling units
  • Compounding extruder screws
  • Spinnerets and small gear pumps

The removal of plastics, especially from inside of complex and expensive tooling, requires an especially gentle yet highly efficient cleaning process.

VACUCLEAN COMPACT, which is conveniently operated using a touchscreen, first gently melts a large part of the adhering plastic; organic residues are safely and completely removed by thermal decomposition (vacuum pyrolysis) with subsequent oxidation. This careful process method is ideal for sensitive parts and tools.

Integrated catalytic exhaust air cleaning system automatically controls the cleaning process, ensuring clean exhaust air and unpolluted waste water.

Being the smallest system of the proven successful VACUCLEAN series, VACUCLEAN COMPACT is the most environmentally friendly system of its kind with the lowest operation and maintenance costs.
