Ceramic Band Heaters
Thermal Corporation
Ceramic Knuckle Band Heaters provide long life and use less
wattage (because of insulation) in plastics extrusion and injection
molding applications. The heaters are constructed with a stainless
steel shroud enclosing high quality ceramic knuckles through which
runs coiled high temperature nickel-chromium element wire. Configuration
choices allow selection of one or two piece heaters, type of closure,
and type of leads/post terminals. Diameters of 2-1/4" or
greater and widths of 1" to 16" are available. Leads
normally exit 180° from gap. Options include terminal boxes,
holes, Heat Saver (extra) insulation, 3-phase power, dual voltages,
partial coverage, European connectors, and perforated sheaths
without insulation for air cooled applications. To order, specify
quantity, configuration, inside diameter, width (increments of
1/2"), wattage, voltage, lead length if applicable and any
options.
Advantages of Ceramic Knuckle Band Heaters:
Lower Operating Cost - Because of superior insulation, less heat escapes to the air and less wattage is required to maintain barrel temperature.Also the heater is safer because the external surface is much cooler
Longer Heater Life - because all materials used are rated to operate at very high temperatures
Higher Operating Temperatures
Flexible - easy to install and remove
Dual Heat Transfer - Heat is transferred through both
radiation and conduction so a near perfect fit is not required
as with other heaters, such as mica heaters
