Purified air during compounding and extrusion

Reliable separation of emissions and fumes from extruders

Considerable demands are placed upon all components to ensure maximum productivity during the refinement and packaging of plastics employing plastics granulation. Besides process technology, a major consideration is the collection of dust and fumes and controlling the air quality inside the workplace.

Keller Lufttechnik has extensive experience with the treatment of dust, fumes, gaseous and adhesive aerosols released during compounding and extrusion processes. Utilizing established technology, emissions are extracted thoroughly at the source and separated in either centralized or decentralized systems.

High-tech plastics are usually delivered to customers as pellets.

Fumes generated during extrusion processes must be reliably extracted in order to meet legal requirements and improve working condition

CLEACOM - established 24/7 technology

Aerosols and fumes are released during extrusion processes. They are captured with collection hoods, rinsed with water and fed to a wet scrubber. The wet scrubber utilizes water as a filtration medium, with the advantage of maximum operational safety despite any adhesive emissions.

Dust from the processing area (mixing, weighing, feeding) is directed to a dry separator.

Contamination and surface dust are manually extracted by means of an additional dry system using a vacuum.

As a general rule, additional designs and configurations are possible, upon request.

Separation of dust and fumes during compounding processes 03

Extraction of fumes at the extruder head: An essential prerequisite for an efficient collection of such fumes is the application of an optimal adjusted extraction hood or other collection elements.

Folding collection hood (option) for an easy cleaning and preliminary spraying.

Adhesive aerosols have a tendency to accumulate in the dirty air ducts. System damage or breakdown could result, with the potential of igniting fires inside the ductwork ....

Atomizing with water at the collection point effectively changes this situation. The dirty air ducts are generally free of deposit build-up, which ensures consistent preliminary separation efficiency for longer periods of time.

Three extraction systems combined accomplish all the extraction requirements

VARIO dry separators in various sizes are used for the extraction of dry bulk material dusts.

For manual dust extraction it would be wise to utilize a highly efficient centralized system even for surface cleaning. Keller Lufttechnik offers a variety of vacuum suction units.

Each solution can be customized: Dry separation for dosing platform and extruder

VDN wet separator, incl. water treatment

Each solution can be customized: Wet and dry separation system,with all components located on the same level.

Each solution can be customized: System installation on three levels
