For the purpose of heating solids, liquids, or gases, split-type cartridge heaters are a particular kind of heating element. They are made in a cylindrical shape to offer focused, localised warmth.

Here are some key features and characteristics of split-type cartridge heaters:

1. Split-type cartridge heaters have an embedded heating element inside a cylindrical metal tube, which is often constructed of stainless steel. A high-resistance wire, such nichrome, is generally twisted inside a ceramic core to serve as the heating element. The term “split” refers to an expansion and installation-friendly longitudinal cut or groove made along the length of the heater.
2. Simple Installation and Replacement: The split design makes it simple to install or replace a cartridge heater in machinery or equipment without having to disassemble it first. The heater is appropriate for uses including plastic injection moulding, hot runner systems, packaging equipment, and more since it may be positioned around cylindrical objects or inserted into bores or holes.
3. Split-type cartridge heaters are capable of functioning at high operating temperatures, typically between 400 and 800 degrees Celsius (1112 and 1472 degrees Fahrenheit). The sheath is made of stainless steel, which has good durability and thermal conductivity.
4. Fast Heat Transfer: Split-type cartridge heaters’ small design enables efficient and quick heat transfer, enabling quick response and speedy attainment of the appropriate temperature.
5. Options for Customization: These heaters can be modified to fit certain needs, including variable lengths, diameters, wattages, and voltages. This enables precise and customised heating solutions based on the requirements of the application.
6. Temperature Control: Split-type cartridge heaters can be used in conjunction with temperature measuring tools like thermocouples  to keep temperatures correct and stable.Split-type cartridge heaters must be installed and insulated properly to avoid electrical shocks and guarantee safe operation. To prevent any potential risks, it is essential to adhere to the manufacturer’s recommendations and safety measures.Split-type cartridge heaters are flexible and frequently employed in industrial operations that need for localised, controlled heating in a small package.
