Advanced Ceramic Heater Elements

ULTRAMIC advanced ceramic heaters are built for demanding thermal applications where speed, cleanliness and reliability are critical. Constructed from aluminium nitride (AlN) with a thermally matched, proprietary heating element, they deliver ramp rates of up to 150°C per second and operate at surface temperatures up to 600°C (1112°F).

Because AlN is dense (>99% theoretical density), non-porous and impervious to moisture, ULTRAMIC heaters provide a clean, non-contaminating heat source — ideal for semiconductor, medical and analytical instrumentation applications. High dielectric strength and leakage current below 10 µA at 500VAC often eliminate the need for isolation transformers, even at standard line voltages.

Key Features

• Ultra-fast ramp rates — up to 150°C (270°F) per second
• High watt density — up to 1000 W/in²
• Operating temperature — up to 600°C (1112°F)
• Low leakage current — <10 µA at 500VAC; <1 µA at 120V
• Clean, non-contaminating — dense, non-porous AlN construction, moisture resistant
• Integrated temperature sensor — optional bonded Type K thermocouple or 100 Ω RTD for accurate, high-response control
• Compact — sizes from as small as 8 mm, replacing multiple components in miniaturised designs
• Compliance — designed to meet UL® and CE standards; RoHS compliant

Applications

• Semiconductor equipment — chip testing and eutectic die bonding, with vacuum holes/grooves, 0.05 mm surface flatness and <1.5 µm surface finish
• Medical devices — respiratory humidification and other patient-critical equipment where low leakage current and small size matter
• Analytical instrumentation — mass spectrometry ion sources and other contamination-sensitive processes
