Extreme temperature resistance (300 degrees)

H Type

Our H-type heater is specially designed for high temperature (maximum surface temperature of 300 degrees C.) uses. Since this type can be set with higher wattage density compared with the standard type, it is recommended to use this H-type for any place where quick heating is required.



  • Different types of heaters such as round, triangle, or ones with holes offered at reasonable prices. Minimum order of one piece, with a quick delivery option.
  • High thermal response due to low thickness, with a standard thickness of 1.5mm.
  • Easy fit on cylinders, cones, and various curved surfaces because of its high flexibility.
  • Available from low temperature through 300°C [572°F].
  • Different designs including low voltage, 100V, 200V and 240V types available.

Power Density


  • Power density range of 0.8-1.5 w/cm2 (5.16-9.68w/in2) is suitable for our H type in most cases, but this rate may vary depending on installation conditions or methods of thermal control. Please contact us with questions.
