  • Aluminum Nitride and Alumina Ceramic Heaters

    Advanced Ceramic Heaters are small in size but mighty in power!

    Compact, High Temperature, Fast Responding Thermal Solutions for Precision Instrumentation
    Durex Industries' ceramic heater technology is available in either Aluminum Nitride (AIN) or Alumina (AI203). Ceramic heater technologies offer significant advantages over metal based sheath heaters that have limitations in thermal performance or material compatibility.  Durex's ceramic heaters can operate in atmospheric and vacuum environments up to 1652°F (900°C). With its excellent thermal efficiency, AIN heaters can be designed with a multi-layer construction that can deliver up to 2000 W/in2. With chemical resistance to most acidic and alkaline solutions, these compact robust heaters are an ideal solution for demanding thermal applications. Ceramic heaters can be custom designed to optimize thermal performance for the instrumentation or equipment's applications.


    Multi Layer Aluminum Nitride Heaters
    AIN heaters are used in applications where low thermal expansion and/or high thermal conductivity are required. When combined with internal chemically bonded metallic conductors, these components may be used in high power electronic devices and rapid thermal cycling processes. Very high power densities can be realized by designing a solution with metallic structures for mounting and heat removal.
