IRD Crystallizing & Drying Handling System

Sunwell’s Infrared Drying Machine (IRD System) is designed for the rapid drying and crystallizing of PET, rPET, and other hygroscopic plastics. Using high-efficiency infrared radiation combined with a rotating drum design, the system achieves extremely fast moisture reduction—ideal for PET sheet extrusion, film lines, bottle-to-bottle recycling, and injection molding pre-treatment.

Key Features

• High-Speed Infrared Drying Technology

  Direct infrared heating penetrates pellets efficiently, delivering rapid energy transfer and significantly faster drying than conventional dehumidifying dryers.

• Fast Moisture Reduction Performance

  Capable of reducing moisture from over 4000 ppm to less than 50 ppm within minutes—critical for PET sheet extrusion and preventing hydrolysis during melt processing.

• Integrated Crystallizing & Drying System

  The tumbling rotating drum ensures uniform material mixing and even exposure to infrared energy, allowing both crystallizing and drying to be completed in a single continuous process.

• Energy-Efficient Operation

  Infrared technology heats the material directly (not the surrounding air), resulting in lower energy consumption, faster start-up, and improved production stability.

• Compact Design for Easy Integration

  A small footprint and simple installation make it ideal for:

  • PET sheet/film extrusion lines
  • PBlow molding
  • PInjection molding
  • PrPET recycling preparation

• Stable Temperature & Process Control

  PLC-controlled system with real-time monitoring ensures consistent drying conditions, stable material IV value, and improved final product quality.

• Perfect for Recycled PET (rPET)

  Effectively removes surface and core moisture from recycled materials, improving melt stability and enabling higher percentages of rPET in your production.
