Specialty HeatersULTRAMIC ® Advanced Ceramic HeatersWatlow’s high performance ULTRAMIC ® advancedceramic heaters are designed for thermal applicationsthat require optimal effectiveness of equipment andprocesses.Constructed with aluminum nitride (AIN), ULTRAMICheaters’ thermally matched proprietary heatingelement provides maximum performance in challengingapplications. AIN is especially suitable for applicationsthat require a clean, non-contaminating heat source.Its excellent geometric stability ensures consistentpart-to-part thermal contact during heating cycles.Watlow AIN heaters operate up to 400°C (752°F) 1with an ultra-fast ramp rate of up to 150°C (270°F) persecond depending on the application, heater design andprocess parameters. In addition to its excellent thermalcharacteristics, the ULTRAMIC provides high electricalisolation and typically provides superior chemicalresistance compared to traditional metal heaters.Performance Capabilities• Standard operating temperature up to 400°C (752°F) 1• Watt densities up to 155 W/cm 2 (1000 W/in 2 )• Temperature ramp rate up to 150°C (270°F)per second (depending on application parameters)Features and BenefitsRobust AIN ceramic• Creates a homogeneous assembly for atmosphericand vacuum applications• Provides durable heater construction and thermaltransfer necessary for high temperature and longheater life• Supports the design of a high watt density, fastresponding heater in a very small package• Ensures geometric stability due to low coefficient ofthermal expansionSuperior electrical performance• Assures low leakage current• Enables high breakdown voltageHigh thermal conductivity• Makes for an ultra-fast temperature ramp rate of up to150°C (270°F) per second (depending on applicationparameters)• Allows for quick cool-down• Provides extremely uniform temperatures over theheater’s surfaceType K thermocouple integrated into assembly• Ensures reliable heater/sensor interface• Improves accuracy with optimized temperature sensing• Provides ramping applications with a high response rateUL ® and CE agency compliance• Meets global safety standards• Includes RoHS complianceTypical Applications• Wire and die bonding• Integrated circuit (IC) chip testing• Mass spectrometry• Medical devices• Plastic welding/sealing• Respiratory therapy equipment1 400°C (752°F) operating temperature is standard.High temperature terminations between 400 and 600°C(752 and 1112°F) are available as an extended capability.Contact your Watlow representative for information.WATLOW ®459
