Tempco - Cast-In Liquid Cooled Band Heater - Plastics Extrusion & Downstream Equipment

Product Description

Tempco Cast-In Band Heaters are manufactured in aluminum alloys because this material provides very good thermal conductive properties. For applications requiring higher operating temperatures and/or higher watt densities, bronze or brass alloys can be used as well.

Liquid cooled Cast-In Band heater is heavily used in plastics extrusion processes.  The cooling function within these heaters is an important feature for maintaining the proper temperature of the barrel.  Therefore, precision machining of the band heater's inside diameter yields superior heat transfer between the heater and machine barrel and is finished to customer specifications.

Specifications:

  • Material: Optional Aluminum 356
  • Maximum Surface Temperature: 750°F (399°C)
  • Density (lb/in3): 0.0968
  • Coefficient of Linear Thermal Expansion (in/in/°F × 10-6): 12.9 @ 68° – 572°F
  • Thermal Conductivity (BTU-in/hr-ft2-°F): 1160

Additional Specifications & Features:

  • See reference pages 3-48 and 3-49 for the Liquid Cool Cast-In Aluminum Heater overview and performance information.
  • See reference pages 3-50 and 3-51 for the Liquid Cool Cast-In Cooling Tube features and specifications.
  • See reference pages 3-52 and 3-53 for the Liquid Cool Cast-In Cooling Tube Termination Options.
  • See reference pages 3-54 and 3-55 for Electrical Termination Options.
  • See reference pages 3-56 and 3-57 for Electrical Terminal Protection Boxes.
  • See reference page 3-58 for selecting the Cast-In Band Heater, and/or replacement Heaters.

  • See reference pages 3-59, 3-60, 3-61, and 3-62 for stock and standard (non-stock) Cast-In Band Heater selections. 
  • See reference page 3-63 for ordering information and quotation form.
    • See reference page 3-74 for Installation and Operation information.

    Design Features:

      Liquid Cooled Band - Single Set of Cooling Tubes

      /Tempco/Data-Assets/03-Cast-In-Images/WebA033.jpg

      The single set cooling tube design features 1/4", 3/8" or 1/2" diameter tubing precisely formed into a serpentine or any other suitable shape and cast into the body of the Cast-In Heater. This is the most widely used method for providing a means of cooling in liquid-cooled Cast-In Heaters. From this basic design, the user can choose to factory equip the cooling tubes with any of the cooling tube termination options.

      Liquid Cooled Band - Dual Set of Cooling Tubes

      /Tempco/Data-Assets/03-Cast-In-Images/WebA014.jpg

      The Dual cooling tube design incorporates two sets of 3/8" or 1/2" diameter tubing formed into a serpentine or any other suitable shape within the same Cast-In Heater. Dual cooling tubes will actually double the operating life of a Cast-In Heater with liquid-cool function, since cooling tube failures usually occur before heating element failures

      Liquid Cooled Band - Dual Set of Cooling Tubes

      /Tempco/Data-Assets/03-Cast-In-Images/WebA004.jpg

      The recessed cooling tube design incorporates 3/8" or 1/2" diameter tubing formed into a serpentine or any other suitable shape with specially designed stainless steel NPT fittings that are welded to the tube ends and cast below the surface of the Cast-In Heater, thus eliminating the troublesome, commonly used tube extensions as they exit the casting for connection to the coolant lines.
