We had the chance to talk to Peter Dal Bo, CCO at Piovan Group, about the new GenesysR drying technology during the Otto Systems presentation at BMB in Brescia. 

Piovan’s Genesys system delivers PET-resin drying with an energy consumption 55% lower than today’s conventional resin-drying systems. GenesysR is a new product – how does it build upon this energy-efficient profile?

Dal Bo: The new product we have presented to our customers during the K show and have officially launched at the PETnology Forum in Nuremberg is GenesysR, the new generation of “reactor drying systems”. Reactor drying is a new technology, combining the benefits of rapid heat up of the PET with a new innovative control of the residual moisture of the resin. Piovan was a supplier of small scale vertical tower SSP systems, a range of products that would find use in the late 80’s, early 90’s, that allowed us to learn in depth about the physical phenomenon taking place in the vertical tower (reactor) while rapidly increasing the polymer temperature. SSP takes place at temperatures of 220°C and in absence of oxygen. GenesysR operates at regular drying temperatures (170 to 180°C) in a dried air environment and, differently from what happens in an SSP process, it does not increase IV but can reduce the drying time from 7 hours to 5 hours. The energy efficiency, a very strong point of the Genesys line, is further increased by 10 Wh/kg, meaning any GenesysR will ensure savings in the range of 60% and beyond when compared to a conventional drying system. Piovan holds the only patent ever released for “High efficiency system for dehumidifying and/or drying plastic materials”, dated 29 May 2013, EP2186613B1, obtained as a consequence of the exceptional results and performance of Genesys.

Is the high productivity of the Genesys also maintained?

Dal Bo: The GenesysR line is particularly suited for high productivity applications, where the benefits of having a very low energy utilization and a highly stable process are exploited in the highest degree. GenesysR benefits of a very innovative control of the residual moisture in the PET, namely AIPC.
