Tempco - Cast-In Air Cooled Band Heater - Finned Casting

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.

Finned Cast-In Band heaters are designed as air-cooled band heaters.  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 3-45, 3-46, and 3-47 for Stock and Standard (non-stock) Finned Aluminum Cast-In Band Heater ordering information.
  • See reference page 3-74 for Cast-In Band Heater installation recommendations.

Design Features:

Finned Type FS1 - Without Side Flanges

These cast-in band heaters are normally made to be used in conjunction with the 'Cool to-the Touch' and 'Multi-Versal Shroud Systems'.  They can also be used as stand alone replacements for other heating and air-cooling extrusion systems.

The standard mounting method for these designs is bolt clamping.  An alternative mounting method is to use stainless steel straps.  Type "T" screw terminals are the standard termination.  For this and other termination styles, see reference pages 3-54 and 3-55

Finned Type FS2 - With Side Flanges

These cast-in band heaters are normally made to be used in conjunction with the Arctic Cast Shroud System.  They can also be used as stand alone replacements for other heating and air-cooling extrusion systems.

The standard mounting method for these designs is bolt clamping.  An alternative mounting method is to use stainless steel straps.  Type "E" screw terminals are the standard termination.  For other termination styles see reference pages 3-54 and 3-55.
