For indirect, efficient heat transfer and controlled drying of sludges, pastes, powders, and granular materials, Holoflite and screw dryers provide a compact and energy-efficient solution trusted across industries. With over 47 years of process equipment expertise, IPP offers immediate access to high-quality used screw dryers and Holoflite units sourced from 20 complete plant sites and included in our inventory of over 15,000 ready-to-ship pieces of equipment. Buying used from IPP helps companies minimize lead times, reduce energy usage, and improve operational performance.
Holoflite and screw dryers use twin intermeshing screws or hollow paddles to convey material through a heated trough while maintaining excellent thermal contact. This low-temperature, indirect drying method is ideal for moisture removal in temperature-sensitive or hazardous materials without risk of combustion or product degradation.
Holoflite and screw dryers are built for corrosion resistance, heat transfer, and durability:
