Industry:	Chemical
Vacuum cleaner:	Ruwac DS 1220 (DustEx zone 22)

Vestolit GmbH is a leading manufacturer of PVC (polyvinyl chloride), which is used primarily for applications in the construction sector (window profiles, tubes, flooring, ...). Vestolit operates Europe’s largest, fully-integrated PVC production system in the Marl Chemical Park, offering an annual capacity of more than 400,000 tons.

Problem

Vestolite is testing the profiles of new types of PVC and their contents at the technology centre, as well as testing their processing capabilities. The application engineers use two extrusion systems to handle the work, along with other equipment. Because these systems need to be converted frequently in technology centre operations, PVC compounds and other production residues can be released into the environment. For Vestolit, it is essential to vacuum this material immediately from the floor or equipment.

Solution

Vestolit uses a DS series Ruwac vacuum cleaner for DustEx zone 22 to handle the task. With a pocket filter designed for dust class M that achieves a residual dust content of 0.1 mg/ m3, the system provides a high standard of employee health protection. The vacuum cleaners are used on more than just the processing systems: they are also part of the compounding system that the application technology uses to create the new material preparations.
