PET dryer boasts new level of energy savings

The Genesys desiccant dryer from Piovan (Venezia, Italy) features integrated automatic air flow control and adjustment to reduce energy consumption by a reported 30%–55% compared with today’s conventional resin drying systems.

Loss-in-weight control, airflow management and stabilization, an intelligent regeneration process, and advanced industrial PC-based control are hallmarks of this next-generation system for PET resin drying, and Piovan claims that it is the only “auto-adaptive” system available on the market today.

Because regeneration of the desiccant material consumes tremendous amounts of energy, Genesys recovers almost the entire energy utilized in this step of the drying process. Based on the minimum energy savings guarantee of 30% from Piovan, a system producing PET preforms running resin at a rate of 1000 kg/hr would save at least 220,000 kW/hr annually. —immeditorial@cancom.com
