A new moisture‑measurement technology, DewTector®, has been launched to help plastics processors and recycling facilities achieve tighter control over the moisture content of powders, granules and regrind materials.
Moisture levels play a critical role in the quality and consistency of polymer processing, influencing melt behaviour, surface finish and mechanical performance. The DewTector® system aims to provide an economical, real‑time method for monitoring these variables without interrupting production.
The system uses a compact sensor arrangement designed to integrate easily into existing conveying, drying or dosing equipment. By continuously measuring moisture levels in the material stream, operators can adjust drying times, airflow or temperature settings to maintain optimal conditions.
This reduces the risk of defects such as bubbles, streaking or brittleness in finished products, while also preventing unnecessary over‑drying, which can waste energy and degrade material properties.
Early adopters report that the system has improved batch‑to‑batch consistency and reduced scrap rates, particularly when processing recycled polymers where moisture variability is common.
The technology is also being used to verify the condition of incoming materials, enabling processors to segregate loads, adjust parameters more quickly and maintain tighter quality assurance standards.
With sustainability pressures increasing across the plastics sector, the ability to process recycled materials more reliably is becoming a competitive advantage. DewTector®’s developers believe the system will help manufacturers meet both regulatory expectations and customer demands for higher‑quality, lower‑impact products.
Further enhancements, including cloud‑based data logging and predictive analytics, are expected later in the year.
