Watlow® Specialty Heaters, such as ULTRAMIC® advanced ceramic heaters are designed for thermal applications. Constructed with aluminum nitride (AIN), ULTRAMIC® heaters’ thermally matched proprietary heating element provides maximum performance in challenging applications. AIN is especially suitable for applications that require a clean, non-contaminating heat source. Its excellent geometric stability ensures consistent part-to-part thermal contact during heating cycles. Watlow® AIN heaters operate up to 400°C (752°F) with an ultra-fast ramp rate of up to 150°C (270°F) per second depending on the application, heater design and process parameters. In addition to its excellent thermal characteristics, the ULTRAMIC provides high electrical isolation and typically provides superior chemical resistance compared to traditional metal heaters.
