DRI-AIR 4-Bed Dual Hopper Portable Dryers

1 dryer, 2 hoppers, 3 reasons why the H-PDII systems provide maximum flexibility:

  • Drying and processing from one hopper while pre-drying in the other; on-the-fly material changes eliminates downtime.
  • Co-injection and/or co-extrusion processes; run two materials at two different temperatures simultaneously.
  • Reduce valuable floor space; eliminate the need for a second dryer by positioning the portable system between two presses/extruders.
