Alumina Heaters

PHOTO: Alumina Heaters

Widely used for automotive and various industrial applications

AL heaters were developed based on ceramic lamination technologies, which are mainly used for highly reliable IC ceramic packages. Thus, these are widely used as a new type of heater in a variety of markets such as automotive, kerosene & gas equipment, and water heating.

Features

  • Rapid heat up
  • Miniature / High power
  • Excellent mechanical properties
  • Durability
  • High efficiency heat exchange
We offer custom-designed alumina heaters upon request, however, we also have several standard designs (open tools) available for small quantity orders or evaluation purposes.
