Solutions · Polyamide Storage
Polyamide absorbs moisture from the air, and moisture affects how it processes. PW Silo Systems designs aluminum and stainless steel silos for PA and nylon pellets – closed storage, process silos for drying, and blending silos for consistent quality.
Polyamide Storage at a Glance
A polyamide silo stores PA or nylon pellets between production, compounding, and injection molding or extrusion. It protects the pellets from contamination and moisture and feeds them reliably to the next step.
Polyamide is hygroscopic – it takes up moisture from the air. That is why closed storage and, where your process requires it, drying in PW ProcessLine process silos are part of the system design.
Why Polyamide Is Demanding
Moisture, consistency, and product separation decide how a PA silo system is built.
Polyamide absorbs moisture from the air, which affects processing.
Some processes require pellets to be degassed, deodorized, or dried before further processing.
Production lots differ, and a silo filled in batches forms layers of different quality.
In coated carbon steel silos, flaking paint and rust particles can end up in the polyamide.
Different polyamide grades and colors must not be mixed by accident.
Polymer production and compounding need large storage capacities – often more than a road-transportable silo can hold.
Silo Materials
We build silos exclusively in aluminum and stainless steel. Both materials offer high corrosion resistance and a long service life – without a coating as the only protection against corrosion.
Which of our two materials fits your polyamide silo depends on your product, your process, and your site. We review it with you.
Your Polyamide Silo System
Storage silos, panel silos, blending silos, process silos, filtration, and safety equipment are engineered as one system. That means fewer interfaces for your team.
Storage
Concentric mass-flow discharge without asymmetric flow zones – as standard, site-assembled, indoor, or multi-compartment silos.

FAQ
Answers to the questions plant managers, engineers, and buyers ask most often about storing polyamide in silos.
These products are on our list of bulk materials tested in our lab:
Specific grades such as PA6, PA66, PA12 powder, and glass-filled polyamide we review with you based on your material data.
A closed silo in aluminum or stainless steel protects the pellets from outside moisture. Where your process requires dried pellets, PW ProcessLine process silos for drying are integrated into the system. We review your requirements with you.
PW BlendLine silos blend and homogenize polymer pellets – with PW PipeBlend or PW CentralPipeBlend, depending on your product and throughput.
Seal-welded PW PanelLine silos reach capacities of up to 53,000 ft³. Their prefabricated components travel in standard containers or on curtain-side trucks – no oversize transport permits – and are assembled on site.
Both are possible. Which material fits your polyamide silo depends on your product, your process, and your site. We review the options with you.
Yes. We deliver to every U.S. state and support your project with silo transport, field assembly, silo installation and supervision, and site relocation of existing systems.
Very likely. Our silo systems are designed for nearly all free-flowing, granular, and powdered bulk solids. Send us your material details – kernel size, moisture, and how the product is filled and discharged – and we will review the right storage solution with you.
Tell us about your polyamide grades, required storage capacity, how the silo is filled and discharged, and your site conditions. Based on this, we work out the material, silo type, and configuration with you and send you a detailed quote.
