The Key Advantages and Uses of Cartridge Heaters


A cartridge heater is a tube-shaped, heavy-duty, industrial joule heating element electrical resistance used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application.Cartridge Heaters are compact and flexible heating elements that are primarily used in industrial settings. This cylindrical-shaped heating element simply comprises resistive wiring enclosed in a metallic sheath. A layer of electrical insulation separates the outer casing from the wires, which are powered by an electrical connection. The diameter of the heating element and its length can vary to suit specific applications. The design and shape of the heater facilitate use of the unit even in complex and narrow structures where conventional heaters fail to reach.
The key benefits stem from the fact that the heater is able to reach and transfer heat wherever required, without losing much energy during the transmission. The protective metallic sheet minimizes oxidation while direct contact proves to be the best method of heat transfer. Minimized energy loss and enhanced effectiveness of the heating process also result in lower electricity bills, which can in fact make a great difference given the scale of industrial operations.
Let’s take a look at the various uses of this heater and the benefits derived in the process.
► A Cartridge Heater comes in handy wherever there is this need to apply a powerful source of heat to temper intricate metallic parts, especially in the case of closed structures such as die blocks and injection moulds. In such cases, the heater snugly fits into small apertures and navigates the intended course to transfer heat at the required point when it comes into contact with the surface.
► This trim, easy-to-use heater finds use in regulating air temperature in devices and components that are prone to condensation such as control panels and closed circuits.
► Compact heating elements fitted to applicators ensure a steady supply of liquid glue for the packaging industry as well.
► These heaters also find use in heating water as well as chemical solutions. Given the water’s natural affinity for electricity, it tends to drain power from the heating elements quite effectively. It is important to determine the heating capacity of the unit based on the volume of water it is required to heat.
► Also used as an engine sump heater, the Cartridge Heater helps maintain the oil reservoir at optimum temperatures to ensure smooth engine operations. Once again, opting for a unit with the right wattage is a must to avoid overheating and carbon build-up, which can insulate the heater and trigger a burn-out.
