Underwater pelletizing system for thermoplastic materials
Optimize your thermoplastic pellet production with a reliable underwater pelletizing solution that ensures consistent pellet quality and efficient drying, minimizing maintenance demands and energy consumption.

Pelletizes and Dries Thermoplastics Efficiently
The ECON EUP series offers superior underwater pelletizing and drying solutions tailored for the plastics and polymer sectors. Each unit features a thermally insulated die plate that prevents material solidification, ensuring seamless pellet production even with fluctuating output rates. Ideal for creating polypropylene granules, polyethylene micro pellets, and more, the system guarantees consistent pellet quality and minimal labor costs.
The EUP series integrates a polymer diverter valve, a pelletizing unit, a water treatment and drying system, and an efficient electrical control system, operating continuously and automatically. Its processing throughput ranges from 30 kg/hr to 15,000 kg/hr, adaptable across varying thermoplastic materials. This adaptability is supported by plug-and-play setup, which includes water treatment and centrifugal drying modules.
With a focus on energy efficiency, the system’s compact design reduces energy consumption, complemented by features like continuous process water filtration and optional automatic band filters. Maintenance is simplified through easy access to components and lack of bypass piping, minimizing upkeep demands. Constructed for durability, the LONGLIFE® die plate extends operation longevity, while optional customization supports varied production goals.
