IRD Crystallizing & Drying Handling System

By combining high-efficiency infrared radiation with a continuous rotating drum design, the Sunwell IRD system delivers extremely fast and uniform moisture removal. Direct energy transfer to the pellets significantly shortens drying time while ensuring stable material quality and consistent downstream processing.

High-Speed Infrared Drying Technology
Direct infrared radiation penetrates pellets efficiently, providing rapid and uniform heating. Compared with conventional hot-air or dehumidifying dryers, the IRD system achieves significantly faster drying performance.

Rapid Moisture Reduction for PET Processing
The system can reduce moisture content from over 4,000 ppm to below 50 ppm within minutes, preventing hydrolysis and maintaining stable IV values during PET extrusion and molding.

Integrated Crystallizing and Drying Process
A rotating tumbling drum ensures continuous material mixing and even exposure to infrared energy, allowing crystallizing and drying to be completed in one single, continuous operation.

Energy-Efficient and Stable Operation
Infrared technology heats the material directly rather than the surrounding air, resulting in lower energy consumption, faster start-up, and improved process stability.

Compact Design with Easy Line Integration
The IRD system features a small footprint and can be easily integrated into:

• PET sheet and film extrusion lines
• Injection molding processes
• Blow molding applications
• rPET recycling and reprocessing lines

PLC-Based Temperature and Process Control
A PLC-controlled system with real-time monitoring ensures precise temperature control, consistent drying conditions, stable material properties, and improved final product quality.
