Vertical Radiant Vacuum Dryer (VRVD)—a groundbreaking solution for the continuous drying of plastic granulates. Designed to operate under vacuum with infrared radiation, the VRVD delivers ultra-fast, energy-efficient drying with minimal thermal stress on materials.

The VRVD energy savings typically result in a return on investment of just one year. This makes it an exceptional choice for plastics producers aiming to boost energy efficiency and sustainability.
The system is compact, modular, and designed for seamless integration into molding, extrusion, compounding, and recycling lines.

Whether you’re drying virgin polymers, masterbatches, or regrind, Saen Engineering’s drying systems ensure consistent quality, lower operating costs, and future-ready performance.

The dryer uses multiple plates on which the material is transported under infrared lamps, thereby heating up as it moves. Due to the vacuum, the water evaporation temperature decreases and all moisture is removed from the material faster than with standard drying methods using dry air or atmospheric pressure.

Modular system. Possibility to configure the system depending on your needs.

Intuitive touch screen control. You can set your own operating parameters and monitor the drying process.

Due to the dry air supply after drying, the material does not absorb moisture from the atmosphere, so you can be sure that your material has the dryness you need.
