APPLICATIONS

  • On machines for plastics processing with operating temperatures of up to 280°C.

SUGGESTIONS FOR ASSEMBLY 

  • Verify that the inner surface of the heater adheres perfectly to the cylinder.
  • Tighten the screws securely. 
  • Re-tighten the screws securely after 30 minutes of operation to compensate for thermal expansion.

DIMENSIONS 

  • The minimum size available is 50 mm diameter, 20 mm wide band. 
  • Over 470 mm in diameter is appropriate to divide the heater into two or more sectors powered separately. 
  • Below 200 mm diameter, the maximum band width is 500 mm. 
  • Above 200 mm diameter, the maximum band width is 600 mm. 
  • We can make holes or pits, with sizes proportional to the heater as necessary.

ELECTRICALPARAMETERS

  • Maximum specific power 4W/cm2 
  • For lengths of more than 80 mm, links are made via three phase star or triangle and single-phase power doubles.
