  • Watlow Ultramic

    Watlow’s high performance ULTRAMIC® advanced ceramic heaters are designed for thermal applications that require optimal effectiveness of equipment and processes.

    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.

    Performance Capabilities

    • Standard operating temperature up to 400 ˚C (752 ˚F)
    • Watt densities up to 155 W/cm² (1000 W/in²)
    • Temperature ramp rate up to 150 ˚C (270 ˚F) per second (depending on application parameters)

  • Watlow Coil & Cable Heaters

    The versatile Watlow coil/cable heater can be formed into a variety of shapes.  Small diameter, high performing cable heaters are fully annealed and readily bent to a multitude of configurations.

    The heater can be formed into a compact, coiled nozzle heater supplying a full 360 degrees of heat with optional distributed wattage.  A straight cable heater can snake through an equipment application.  Flat, spiral configurations can be used in high-tech manufacturing while a star wound cable can be used for air and gas heating.

    Different applications require different construction methods, including one, two or four resistance wires; parallel coil or straight wire; drawn or swaged sheaths; with or without internal thermocouples; leads exiting from one or both ends, and round, rectangular or square cable cross sectionals.

    Whatever the application requirement, a Watlow coil/cable heater can be shaped to fit.

  • FLUENT In-Line Heater

    Watlow's FLUENT® in-line fluid heater is a small, lightweight, high-performance heater that can replace both a traditional immersion type heater or a heater wrapped around a tube as part of a thermal system.  Watlow's FLUENT heater is designed as an integrated solution that replaces multiple components in a system.  This heater design reduces overall system cost and complexity.  Because of its high watt density, it offers ultra-fast response leading to high system performance.  Featuring Watlow's patented layered heater technology, the heater makes use of its entire surface to produce heat, which optimizes heat transfer and termparture uniformity.
