Aluminum Nitride Heater
Aluminum nitride (AlN) is a versatile material most commonly used where high thermal conductivity and electrical insulation are required. This unique ability, combined with its low toxicity, makes AIN ideal for rapidly heating and dissipating heat from other components and systems. We supply aluminum nitride heaters.
The AlN Heater is designed for thermal applications that require a high-performance ceramic heater to ensure optimal results for the equipment or process. AlN is particularly suited to applications that require clean, contaminant-free sources. Aluminum nitride ceramic heaters can provide temperatures up to 500°C with an ultra-fast ramp rate of 150°C, depending on the application, design, and process parameters. In addition to superior thermal conductivity, aluminum nitride ceramic heaters have high galvanic isolation properties and typically achieve excellent chemical resistance compared to conventional metal heaters.
Edgetech Industries, Advanced Ceramics Division supplies high-quality Aluminum Nitride Ceramic heaters at competitive prices.
