plastics industry
In the plastics industry, air technology and material logistics play a key role in determining quality, efficiency and system availability. Venti Oelde offers integrated solutions for demanding processes - from the collection and treatment of exhaust air to the reliable conveying and separation of materials.
Reliable air technology for the highest demands
From plastics processing and recycling to extrusion, compounding, thermoforming and film production, air flow, extraction, dust removal and drying determine the quality and efficiency of the processes. This is why the plastics industry demands precisely tailored, process-reliable air technology – particularly for temperature-critical processes, fine polymer dusts, high filter loads, VOC-emitting extrusion processes, abrasive recycled material, sticky dusts and stringent emission limits.
Venti Oelde combines decades of experience with state-of-the-art development tools such as CFD analysis and FEM calculations. This results in integrated, comprehensive air handling systems that cover all relevant components and process steps – from filters and cyclones to fans, heat recovery, edge strip extraction and process-optimised material logistics.
with complete ventilation systems that run reliably.
Examples from practice
Extrusion and blowfilm production
Controlled exhaust air flow, cooling and humidity control, as well as the removal of VOC-laden process air.
Injection moulding and thermoforming
Clean air zones and the safe removal of thermal emissions and airborne particles.
Compounding and masterbatch
Separation of ultra-fine particles – robust even with abrasive polymer blends.
Recycling and crushing
Dust extraction, material separation and the separation of lightweight fractions, as well as the safe removal of dusts that pose a potential explosion hazard.
Grinding and screening processes
Process-stable dust separation using filter systems that operate trouble-free even with high loads of fibre or film fragments.
Service areas
Dedusting Technologies
High-performance industrial filters, purge air and pulse filters, as well as cylindrical and cyclone filters for plastic dust, ground material particles, fibres and flakes. Pressure-surge-resistant, ATEX-compliant designs ensure safe operation even with potentially explosive polymer dusts. Modular systems allow for easy expansion and a long service life.
Conveyance Solutions
Energy-optimised conveying and separation systems for regrind, film scraps, lightweight fractions, sprues and edge strips. Custom-designed piping systems with optimal flow characteristics reduce energy consumption and enhance process stability.
Exhaust Air Collection & Treatment
Process air containing VOCs from extrusion, thermoforming and drying processes is collected in a controlled manner, safely vented and, where necessary, purified. Heat recovery significantly reduces energy consumption and improves the environmental performance of the entire plant.
Ventilation Solutions
Air management systems for production areas involving sensitive plastics processes: controlled temperature and humidity management, protection against particle ingress, and safe extraction of thermal process air.
Cooling Systems
Targeted air cooling for extrusion lines, rolling mills, die areas or grinding processes. The precisely controlled airflow stabilises material viscosity, withdrawal speed and cooling behaviour.
Sorting & Seperating
Air-based separation of flakes, film scraps, sprues or fine particles. Venti-Sicht separation systems enable clean further processing and improve the quality of the recycled material.
Drying Solutions
Process air systems for drying plastic granules, compounds or recycled material. Energy-efficient drying systems with precise air distribution ensure consistent residual moisture levels and stable further processing.
