Drying with less energy than ever

Loss-in-weight control, airflow management and stabilization, an intelligent regeneration process, and advanced industrial PC-based control combine in an auto-adaptive PET resin drying solution that claims to deliver the lowest possible energy consumption.

PET resin drying is all the more energy-efficient with the Genesys dryer.

A typical resin drying process consumes a large volume of energy, requiring the resin to be exposed to hot, dry air for up to as much as six hours. Given the high cost of energy today, tremendous effort is being focused on improving this process to be more energy efficient according to supplier Piovan (Santa Maria di Sala, Italy), which adds that airflow management and stabilization is key to controlling energy consumption. Piovan has integrated automatic airflow control and adjustment to reduce energy consumption by 35-55% below today's conventional resin drying systems.

Another feature of Genesys is the capability to stabilize the airflow in the drying hopper for further drastic optimization of energy utilization. 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. By doing this, Genesys is able to provide savings of 50-80% when compared to traditional or current regeneration technology. 

Piovan says Genesys can provide the lowest energy consumption, when compared to any other drying technology available today, guaranteeing overall savings of 30% and up. For a system producing PET performs running resin at a rate of 1000 kg/hr, this represents a savings of at least 220,000 kW/hr/yr. A Genesys system consisting of one GP55 dryer equipped with a TN300 dehumidifying hopper will be displayed at K 2010 at Stand 9/C59. —[email protected]
