<strong>Barrel</strong> <strong>Heaters</strong>Ceramic KnuckleBandCeramic knuckle band heaters aredesigned to provide high-performancebarrel heating at temperaturesup to 760°C (1400°F). This level ofperformance is achieved from theceramic knuckles that provide excellentinsulation and long heater life.The construction of the ceramicknuckle heater includes interlockingceramic blocks with resistance wiresthreaded through holes within theceramic. This method providessuperior heat distribution across theband, resulting in a uniformly heatedsurface. Ceramic knuckle heatersare specifically engineered andmanufactured with three layers:• Aluminized steel sheath layerimproves mechanical protectionto heater and resists corrosion.• Ceramic fiber layer providesthermal insulation, energy conservationand minimizes heat loss.• Ceramic knuckle layer providesmechanical protectionand electrical insulation to theresistance element, whichincreases heater life and conductsor radiates the heat tothe surface.Performance Capabilities• 760°C (1400°F) maximumoperational temperatures• Watt densities up to 45 W/in 2Features and BenefitsCeramic insulator• Allows for high temperatureoperation• Provides longer heater life• Accurate heatingAluminized steel cover• Provides excellent protection fromabrasionRadiation or conduction heattransfer• Ensures dependable heat transfermethodStandard Construction• Aluminized sheath• Clamp tabs• Post terminalsApplications• Injection molding barrels• Extruder barrels• Blown film dies14
