In the field of drying, Piovan has developed the application of an innovative technology: the use of a rotor with a honeycomb structure to eliminate the humidity released by plastic material during the drying process.
This brand-new series, presented for the first time at the K2007 show, consists of four models that operate in a temperature range from 80 to 150°C, with air flows from 50 to 200 m³/h: HR50, HR100, HR150 and HR200.
The new HR dryers present numerous advantages such as:

- No expense for the connection of cooling water or compressed air and no running costs for such services because the HR units require only electric power supply;
- 50% reduction of the use of energy;
- Stable Dew Point, featuring set-up values in a range down to -50°C;
- Easy access to all machine components allowing Simplified maintenance
- Guaranteed absence of dust and of material contamination, making the HR dryers suitable for application in the medical and optical sectors too;
- Continuity of operation of the honeycomb rotor ensured by the new drive mechanism furnished with a wear-resistant Kevlar reinforced belt which eliminates traditional maintenance operations or lubrication, necessary when using rudimental belts or chains.
