Teubert Pre-Expander (TDV)


Teubert Pre-Expander (TDV)

Our Teubert Pre-Expander (TDV) for EPS and Copolymere has been developed especially for Lost Foam and laboratory use. It can be opened completely in seconds.

Our Teubert Pre-Expander is characterized by the following technical details:

  • pre-expansion vessel made of aluminum, easy to open, makes cleaning simple
  • frequency controlled stirring mechanism for the precise distribution of the material inside the pre-expansion vessel during the pre-expansion phase
  • injection of air and steam through the rotor system
  • weighing unit, located separately from the expansion vessel, including the raw material hopper and a pressure transport unit for the accurate metering of the raw material
  • raw material conveyor system
  • fluidized drying bed made of steel, including heating- and transport blower and slotted stainless steel sheets
  • sieve- /delumping unit
  • blower for the transport of the pre-expanded bead to the silo system for intermediate storage
  • easy check to record maximum pressure and temperature curves
  • digital steam regulation for precise adjustment of the steam pressure
  • temperature monitoring of the pre-expansion vessel
  • optical safety switch-off at maximum filling level
  • steam inlet and outlet through removable aluminum sheets with core vents
  • finished density control
