Cartridge Heater (Pencil Heater)
Cartridge Heater also called as Pencil Heater, we can manufacture ¼” to 1” diameter Cartridge heater as per the client customization.
A cartridge heater is a tube-shaped, heavy-duty, industrial Joule heating element used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application. Compact designs are capable of reaching a watt density of up to 50W/cm² while some specialty high temperature designs can reach 100W/cm².
