Durex Industries’ Rapid Fire aluminum nitride (AlN) ceramic heater solutions combine the thermal conductivity of aluminum and dielectric strength of specialty ceramics with physical properties similar to stainless steel. Additionally, a tungsten (W) RTD Sensor is integrated into the multi-layer heater construction to provide maximum control of this high watt density heater. New levels of machine design and thermal performance can be achieved through the excellent thermal, dielectric and physical properties of AlN heaters.
Ceramic heater technologies offer significant advantages over metal based sheath heaters that have limitations in thermal performance or material compatibility. Durex’ ceramic heaters can operate in atmospheric and vacuum environments up to 1000°C (1832°F). With its excellent thermal conductivity, AlN heaters can be designed with a multilayer construction that can deliver up to 2000 W/in2 (310 W/cm2 ). 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 instrumentation and equipment applications.
Thermal conductivity equivalent to aluminum for fast and uniform thermal response
Watt density higher than any metal or ceramic heater technology for concentrated heat in a small area
Integrated RTD sensor for optimum heater temperature control
Dielectric strength eliminates need for magnesium oxide insulation (MgO) layer used in metal heaters
