Founded in 1986 in Bochum, Germany, ENTEX (short for extrusion development) was built around one central idea: how can we extrude better? Its founder, Dipl.-Ing. Harald Rust believed that extrusion could do more if machines were more intelligent, gentler, and more versatile.

From small beginnings, ENTEX has grown into the world leader in planetary roller extruders, backed by decades of development, innovation, and more than 160 registered intellectual property rights.

What Makes Their Planetary Roller Extruder (PRE) Unique

Here are the features and technology that set ENTEX apart — especially their planetary roller concept:

• Planetary roller design: A central spindle with multiple “planet” rollers that rotate and roll around it. This design gives excellent mixing, high surface area, and repeated thin-layer rolling, which improves heat transfer and temperature control.
• Modular build: Their extruders can be configured with up to 8 roller modules, allowing customization of process steps (mixing, degassing, cooling, etc.). You can modify thermal/mechanical segments, add injection or degassing stages, etc.
• Low shear / gentle processing: Because the material gets rolled and worked rather than forced aggressively, the PRE is perfect for sensitive materials (adhesives, reactive resins, elastomers) where you want to avoid overheating or damage.
• Precise temperature control: Because of all the thin layers, many contact surfaces, modular zones, and cooling/tempering options, ENTEX machines give you fine control over thermal input. This is especially critical in reactive or temperature-sensitive processes.
• Range of sizes & applications: From lab-/pilot-scale versions to full production lines. Materials range broadly: PVC, plastics, elastomers, adhesives, food applications, recycling, etc.

Industries Benefiting from ENTEX Technology

• Plastics / Compounding (PVC, filled polyolefins, etc.)
• Rubber and Elastomers
• Adhesives & Sealants
• Recycling / Sustainability Applications
• Chemicals, Reactive Extrusion, Degassing Processes
• Food / Thermally Sensitive Products

Why ENTEX Equipment Matters

Because of their advanced roller geometry, modularity, and precise thermal control, ENTEX planetary roller extruders often offer benefits like:

• More uniform mixing & dispersion
• Ability to handle tricky or sensitive materials without degrading them
• Reduced residence time / better control over shear and mechanical stress
• Flexibility to switch between processes (additives, degassing, cooling stages)
• Efficiency and sustainability: better energy usage, less waste, often lower operational cost for complex or reactive processes

The Arlington Advantage

Here’s how Arlington adds value when you consider used ENTEX machines:

Inspection and Refurbishment: Before listing, we thoroughly inspect used machines, verify module wear, assess temperature control parts, check for damage or overuse, calibrate where needed, etc.

Cost Savings, Faster ROI: Used ENTEX equipment can deliver much of the performance of new machines at significantly lower cost. Because ENTEX designs are durable and modular, a well-maintained used unit often still has a long life ahead.

Faster Availability: Lead times for new machines can be long. If you need production ASAP, used ENTEX systems can often be delivered and installed more quickly.

Support & Parts Availability

ENTEX is well-supported globally, and we help with sourcing parts, service, and integration. Even with used machines, you can get support, retrofit or upgrade modules, etc.

Arlington Trust & Transparency

We’ve been in the business for years. We stand behind our machines. If there are limitations—age, module wear, past usage—we’ll tell you so you can make the right decision.

How ENTEX + Arlington Can Drive Your Success

When you combine ENTEX’s advanced planetary roller extrusion technology with Arlington’s experience in used machinery, you get a powerful solution: high-precision, high-flexibility machines that won’t break the bank, delivered faster, backed by real expertise.

If your process requires excellent temperature control, the ability to work with sensitive or reactive materials, or a demand for continuous compounding with high performance, looking at used ENTEX planetary roller extruders through Arlington might be one of the best investments you make for your production floor.
