1. Introdution for Stainless Steel Cartridge Heater
Cartridge heaters are most frequently used for heating metal parts by insertion into drilled holes. Two basic forms, high watt density and low watt density. High density cartridge heaters are available with various termination styles and mounting attachments. In high-density cartridge heaters the resistance wire loops are positioned as close as possible to the outside shell.
