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:
CT is a system for PET crystallization.
It can be used to treat recycled PET (bottles, flacons, etc.) in flakes and regrind in amorphous state.
CTs are equipped with an exclusive regulation system that optimizes the start-up phase of the crystallization process.
It allows to obtain a crystalline material, ready for the subsequent dehumidification phase.
WIND is an innovative system for treatment of crystalline PET. WIND systems work completely automatically, without molecular sieves or electromagnetic waves in general and no need for chilled water.
WIND systems include:
Each WIND must be used in combination with a process hopper, specifically chosen according to the required hourly production, with all needed accessories.
WIND is an absolutely revolutionary system, whose main advantages are:
Thanks to WIND technology, that monitors all the parameters and process variables involved, combined with the constructive peculiarities of the machine, this system is able to guarantee an adequate treatment of crystalline PET.
WIND can therefore reduce power consumption, initial investment of traditional systems and ensuring a higher performance.
DDT series dehumidifiers are deployed specifically in high temperature treatment, including PET dehumidification.
They are suitable for crystalline PET in granules, or pellets (virgin or reground) and flakes previously subject to crystallization treatment.
The main plastics fields where these systems can be employed are:
They can be integrated with dedicated conveying systems (transport in loop circuit with dehumidified air, maintenance hopper in dehumidified environment, etc.)
