Cartridge Heaters
Cartridge Heaters are typically inserted into drilled holes to heat platens and molds or used as liquid immersion heaters.
Common Applications
Hi-Density Cartridge Heaters
Swaged Construction permits higher watt densities. Standard 321SS and optional Incoloy 800 sheath provide good thermal conductivity and resistance to corrosion and scaling.

Hi-Density 1/8″ Miniature Cartridge Heaters
Swaged Construction permits higher watt densities. Standard 304SS and optional Inconel 600 sheath provide good thermal conductivity and resistance to corrosion and scaling.
Hi-Density Cartridge Heaters in Metric Sizes
Swaged Construction permits higher watt densities. Standard 321SS and optional Incoloy 800 sheath provide good thermal conductivity and resistance to corrosion and scaling.
Low Density Cartridge Heaters
An economical heater used in applications requiring lower operating temperatures and watt densities.
Immersion Cartridge Heaters
These heaters are designed for heating water and other liquids. The high watt density capabilities of this heater permit greater heat dissipation in a given area than would a tubular immersion heater. For water heating, watt densities of several hundred watts per square inch are possible; oil heating may be limited to 5 to 20 watts per square inch.
In-Line Forced Air Heaters
Cartridge type forced air heaters are ideal for Small Volume Air & Gas Heating.
Pennybottom Cartridge Heaters
The unique feature of the Pennybottom™ cartridge heater is the use of a flat copper end disc to maximize heat transfer and improve temperature sensing. The Pennybottom™ cartridge heater also includes a Type J thermocouple at the end disc. The junction is grounded to the flat copper end disc, providing excellent temperature control at the gating area, eliminating freeze-ups or drool, thus producing quality molded parts.
Underwater Pelletizer Die Cartridge Heaters
These Hi-Density cartridge heaters are designed as an exact replacement for an OEM application.
Bolt Cartridge Heaters
Bolt Heaters are used as an aid to tighten large bolts in heavy machinery and equipment. Heaters are sized for easy insertion into a hollow bolt. The rapid heating of the bolt expands it, allowing further tightening of the nut. The heater is then de-energized and removed. As the bolt cools, its contraction back to original size provides a tight fit.
Square Cartridge Heaters
Inserted in a milled slot Square cartridge heaters allow more contact per linear inch than a cylindrical cartridge heater, for greater heat transfer to the surrounding medium.
Specific Use Cartridge Heaters
The different types of construction and numerous options available allow cartridge heaters to be customized to perform in many different applications.
BNS Anti-Seize Cartridge Heater Coating
This high temperature, electrically insulating and thermally conductive coating will minimize oxidation and improve heat transfer from heater to the object being heated and is formulated to assist in the removal of cartridge heaters.
