Seven musts at Fakuma 2014 (slideshow): Moretto

Following extensive R&D dedicated to plastics dehumidification processes, ancillary equipment maker Moretto S.p.A. (Massanzago, Italy) will show its Eureka material conditioning system at Fakuma.

Consisting of three elements—a Flowmatik airflow management and distribution system, OTX hopper drier, and X Max drier—Eureka has closed the loop and created a highly efficient drying system, says company CEO Renato Moretto. Eureka is the most advanced drying system for engineering thermoplastics and the only one that can process 10,000 to 12,000 kg/h of material in compounding, extrusion, and PET processing while reducing energy consumption by as much as 56%, according to Moretto.

The core X Max drier is based on Moretto’s patented X technology and incorporates a multibed single molecular sieve desiccant system providing constant –65° to –85°C dew point. Although it is twice the size of conventional beds, it does not require cooling water or compressed air for the changeover valve. It also features complete energy recovery via rotation, as heat is recovered from bed cooling during molecular sieve regeneration. A key enhancement to the X Max drier, which will be showcased at Fakuma, is the multistage centrifugal blower, developed by Moretto in a collaborative project with Padua University. The combination of these features improves the efficiency of the X Max drier line. The X MAX 916, for example, provides each unit with up to 1600 m³/h drying capacity at 300-mbar pressure with exceptionally low electricity consumption of just 13.2 kWh.
