VACUCLEAN

Product catalog summary

Introduction
SCHWING Fluid Technik GmbH specializes in thermal cleaning technologies, particularly the VACUCLEAN system, designed for the removal of polymer and organic contaminants from metal parts and tools. The document outlines the specifications, operating principles, and applications of the VACUCLEAN system.

Specifications
The VACUCLEAN system is available in various models, including the 1713-XXL version, which can handle up to 12,500 kg. It is not suitable for polymers containing halogens or flame retardants. The system operates under vacuum conditions with adjustable temperatures up to 450°C, extendable to 600°C for special applications.

Operating Principle
The cleaning process involves three main stages: Heat-Up & Melt-Off, Pyrolysis, and Oxidation. The system gently heats parts under vacuum, allowing molten polymers to drain into a collector. Pyrolysis initiates thermal decomposition of contaminants, while oxidation removes remaining carbon residues. The entire process is automated and controlled to prevent overheating.

Technical Data
The document provides detailed technical data for standard sizes, including dimensions, weight capacities, temperature ranges, and electrical requirements. The VACUCLEAN system requires only electricity and water, ensuring low operating and maintenance costs.

Applications
VACUCLEAN is ideal for cleaning components such as spinnerets, spin packs, nonwoven dies, and extruder screws. It is widely used in industries like synthetic fiber production, polymer production, extrusion, and injection molding.

Advantages
The system offers perfect cleaning results, even for complex dies, with no carbon residues. It is easy to operate, environmentally friendly, and features off-gas cleaning by a catalytic converter. The process is fully automated, ensuring precise temperature control and minimal risk of distortion.

Conclusion
SCHWING's VACUCLEAN system represents advanced engineering for efficient and environmentally friendly cleaning of metal parts in various industrial applications.
