steatite ceramic for band heater
Ceramic Band heaters
Ceramic Band Heaters provide long life and use less wattage in plastics extrusion and injection molding applications.These band heaters are constructed with a stainless steel shroud enclosing high quality ceramic knuckles through which run 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 coverages,European connectors,and perforated sheaths without insualtion for air cooled applications.To order,specify quantity,configuration,inside diameter,width,voltage,lead length if applicable and any options.
Advantage of Ceramic Band Heaters
A. 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.
B. Operator comfort-with the majority of the heat going directly to your process,the ceramic band heater gives off significantly less heat to ambient air than a mica band heater.
C. Longer heater life-because all materials used are rated to operate at very high temperatures.
D. Higher operating temperatures
E. Flexible-easy to install and remove
F. Dual heat transfer-heat is transferred through both radiation and conduction so a near perfect fit is not required with other heaters,such as mica heaters.
