Eureka drying system

Eureka: the drying system for up to 12,000 kg/h

  • Renato Moretto’s “most ambitious project in the history of dehumidification”
  • Up to 56% lower energy consumption
  • Up to 12,000 kg/h of material

Ancillary equipment producer Moretto S.p.A. will present its Eureka plastics material conditioning system at Fakuma 2014. The system has been developed over a 13-year period of simulation, experimentation and testing, leading to what company founder and CEO Renato Moretto describes as “the most ambitious project in the history of dehumidification during my 45 years carrier in the plastics world”. And according to Moretto, the only drying system that can process 10,000 to 12,000 kg/h of material in compounding, extrusion and PET processing, where it has up to 56% lower energy consumption than traditional drying systems.

Energy recovery by rotation, heat recovered from cooling

The Eureka system consists of three elements: a Flowmatik airflow management and distribution system, the OTX hopper dryer and the X Max dryer. The core X Max dryer is based on Moretto’s patented “X technology” and incorporates a multi bed single molecular sieve desiccant system providing constant –65°C to –85°C dew point. Although twice the size of conventional beds, it not only works without requiring cooling water or compressed air for the changeover valve, but also features complete energy recovery by rotation, heat being recovered from cooling of the bed during molecular sieve regeneration.

Due to these combined features, the X Max dryer is highly efficient, the X MAX 916 model for example providing each unit up to 1,600 m³/h drying capacity at 300 mbar pressure with exceptionally low electricity consumption of just 13.2 kWh.

Combination of dryers provides air flow rate of up to 20,000 m3/h

From two to ten X Max dryers can be combined, providing extremely large drying capacity, with up to 20,000 m3/h airflow rate when using 10 units. Should full system drying capacity not be required, the Flowmatik airflow management unit, first launched at Fakuma 2005, can stop one or more dryers and distribute the reduced load over the other dryers, as well as sharing air with up to 32 truncated cone shaped OTX (Original Thermal Exchanger) hopper dryers. The OTX is available in 28 sizes and its internal geometry ensures even material and air flow through the hopper for maximum drying efficiency.
