Cleanliness and safety in catalytic converter production

Customer: Evonik Catalysts Chemical park
Extracted material: Solid chemicals
Industry: Chemical
Vacuum cleaner: two Ruwac DS 1220 GasEx

Evonik Industries AG is one of the world's leading manufacturers of specialised chemicals and high-performance materials. The “Catalysts” business area produces catalytic converters at multiple locations – in Marl, for example, they produce fixed-bed catalysts that accelerate chemical production processes and make them more energy and cost efficient.


The steps to produce catalytic converters include moulding, impregnation, coating and thermal treatment, for example, and dust production is unavoidable. To ensure good occupational safety, the company needed to extract residues from filling or from a product exchange immediately. This was particularly important as some of the dusts are explosive.


Evonik uses two DustEx vacuum cleaners from Ruwac to handle the task. They were designed from the ground up for use in dust explosion hazard areas, and are also extremely flexible. They offer easy transportation to the work site, and a variety of different suction nozzles, brushes, etc., which Evonik ordered as accessories. They ensure all cleaning tasks on the floor or on or in machines can be conducted efficiently and thoroughly, using the right “tool.”

Since the managers in Evonik catalytic converter production value low-noise machine and equipment operation, one of the two DS 1 series Ruwac Ex vacuum cleaners is designed as a 2.2 kW “quiet-running vacuum”.
