Heater Product Information

List of heater products

  • Mica heater
    Ultra-thin, high W precision

    Used in a wide range of fields as a heat source able to support various heating and drying needs such as liquid crystal, semiconductor, metals and more.

  • Hot plate
    Excellent maintenance characteristics

    Heating hot plates are suitable to many kinds of testing equipment.

  • AlN hot plate
    Can be designed to match your application

    The electrical resistance ratio of the element can be arbitrarily adjusted enabling designs of heater output that match the application whether low or high temperature range is needed.

  • Jacket heater
    Can be designed to match your application

    Used in pipe, valve and filter heating applications. Primary applications are related to semiconductors and liquid crystals but able to support other applications such as analytical devices.

High Performance Thermal Insulation Product Information

List of insulation products

  • High performance thermal insulation WDS®
    Controlling the movement of heat through fixed transfer, air molecule movement and infrared transparency enables achieving low thermal transmission rates without still air.
  • Thermal insulating ring
    Applied ceramic fiber products

    These products were developed as high temperature thermal insulation for semiconductor manufacturing processes such as in diffusion furnace and CVD equipment.
