WD is a innovative system for treatment of amorphous and crystalline PET with energy and environmental protection solutions.
WD systems offer the patented "WIND-DRYER" technology, which is characterized by the absence of molecular sieves, combined with the YES-System technology for maximum energy efficiency.
Loading of WD takes place through an integrated gravimetric dosing system with up to three components.
WD can be used to treat recycled PET (bottles, flacons, etc.) but also virgin, in granules, micro-granules, flakes with high dustiness, both in amorphous and crystalline state.
Thanks to the WIND-DRYER technology, which monitors all the parameters and process variables involved, combined with the constructional features of the system, WDs are able to ensure correct crystallization of amorphous PET in just 10 minutes, and adequate dehumidification of crystalline PET in just 80 minutes, for a total treatment time of max. 90 minutes without any need for traditional molecular sieve dehumidifiers.
WDs are therefore able to reduce the time and consumption of traditional crystallization and dehumidification on one hand, and to reduce the initial investment costs typical of IR systems on the other hand, while ensuring, in both situations, a higher performance.
Main features of WD systems are:
