Cartridge Heaters are typically inserted into drilled holes to heat platens and molds or used as liquid immersion heaters.
Swaged Construction permits higher watt densities.
Standard 321SS and optional Incoloy 800 sheath provde good thermal conductivity and resistance to corrosion and scaling.
An economical heater used in applications requiring lower operating temperatures and watt densities.
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.
Cartridge type forced air heaters are ideal for Small Volume Air & Gas Heating.
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.
These Hi-Density cartridge heaters are designed as an exact replacement for an OEM application.
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.
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.
The different types of construction and numerous options available allow cartridge heaters to be customized to perform in many different applications.
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.
