Vacuum dryer

drv series

The DRV Series is the most innovative and advanced drying system on the market, featuring multiple patents by PET Solutions.


It is designed primarily for recycled materials but also extends its application to virgin materials.
The DRV Series is equipped with vacuum process technology that enables the extraction of VOC contaminants (such as Benzene, Limonene, etc.) commonly found in rPET due to the presence of foreign substances (like metal, glass, paper), additives, and immiscible polymers (such as PVC, PP, etc.).


Thanks to this vacuum technology, the system no longer requires molecular sieves and makes oil condensers obsolete, as it is capable of removing all VOC contaminants directly through the vacuum process.


The range covers production capacities from 500 to 1500 kg/h, with a final residual moisture content of less than 40 ppm.

TECHNICAL SPECIFICATION

Microprocessor control with 7” TOUCH display and easy programming (material type selectable from database and consumption per hour).

PLC control.

4 hoppers for 4 drying phases (pre-heating, heating, vacuum and maintenance).

Liquid ring vacuum pump.

Temperature control and management during the drying phases.

Level sensors for residence time monitoring.

Temperature sensors for process management.

Automatic shutdown to prevent pellet degradation

RS485 Modbus interface.

ADDED VALUE

Material changeover and system startup: the DRV series technology reduces material changeover time by 65%, cutting it from 6 hours (standard drying) to 2 hours (vacuum drying).

Energy consumption reduction: the vacuum system ensures energy usage between 70 and 80 W/kg depending on the application with virgin or rPET material, while a traditional system can consume up to 120 W/kg with rPET.

Reduced maintenance: maintenance is limited to simple filter cleaning, with no traditional heat exchangers or molecular sieves required as in standard drying systems.

Easy control: the user interface with multilingual digital display and keypad provides continuous machine monitoring, highlighting key parameters such as temperature, material level in the hopper, vacuum level, etc.

Utility reduction: the system requires only electrical and pneumatic connections, eliminating the need for HTC network connection. Effective removal of residual oil contaminants from the process air generated by recycled plastic material.
