Stainless steel drying hoppers for plastic processing
Optimize moisture control for thermoplastics with robust drying hoppers, designed to enhance efficiency by preventing moisture-related defects in plastic production lines.

Dries and Insulates Thermoplastics and Industrial Materials
The WH Series Drying Hoppers, featured in AEC’s latest offerings, provide an innovative solution for plastics manufacturers facing moisture control challenges in thermoplastic processing. These hoppers utilize a unique mass-flow design, ensuring consistent drying while minimizing thermal waste with dual-wall insulation and stainless steel interiors. Their application spans across various industries for end-products such as plastic automotive parts, PET bottles, and HDPE containers. These hoppers readily integrate into processing lines, suitable for both stand or machine-mounted configurations, and offer substantial versatility in operations, from manual to continuous small to medium-scale processing. Equipped with energy-efficient 60mm insulation and strategic material shut-off features, they not only lower energy consumption but also facilitate easy maintenance with large access doors and quick-release clamps. Optional features such as metric-to-imperial hose adapters and adjustable proximity sensor assemblies further allow customization to meet specific production needs.
