Two-Circuit Technology

HD Series

Two-circuit technology for highest throughputs

The HD series uses the revolutionary two-circuit technology and delivers immense energy savings thanks to extremely low compressed air consumption. The widespread prejudice that compressed air is uneconomical for the drying process at large hopper volumes is a thing of the past with this technology. The appliances are mainly used for drying hygroscopic plastics with very high material throughputs. The compact design requires minimum space for installation. All sizes are equipped with a static stand.
