Tempered Water Systems (TWS)


The TWS is the internal conveying system of the pelletizing process. The capacity of the TWS depends on the production volume and the product to be pelletized.

Temperature, water flow rate and residence time of the pellets in the process water are the key factors for sizing a TWS. As a rule, the tempered water system is a compact unit including the following main components:

  • Agglomerate catcher
  • Centrifugal dryer
  • Exhaust fan
  • Water tank with heater and integrated sieve (IS) filtration
  • Pump / Heat exchanger
Optional integration is possible for:
  • Fines removal sieve (FRS or DFRS)
  • Pellet diverter valve

The process water heated by the pellet flow is separated in the centrifugal dryer. The process water remains in the closed loop and is collected in the process water tank. A heat exchanger ensures constant water temperature. The process water is filtered and re-circulated to the pelletizer cutting chamber. The TWS can be installed on suitable stands or be distributed across several floors, depending on the floor plan.
