Advantages of Cartridge Heaters

Semiconductor Manufacturing

• High Heat Density – Concentrated heating in a small space.
• Precision Temperature Control – Often used with thermocouples for accuracy.
• Easy Installation – Press-fit or clamped into drilled holes.
• Durable Construction – Typically stainless steel or Incoloy sheath.
• Customizable – Available in various diameters, lengths, and wattages.
