Most cartridge heaters have a standard electrical connection. However, there are other cable designs to choose from, including a right-angle exit, fixing tab and flange mounting, to name a few. Cartridge heaters offer superior heat transfer. The heating element is inserted snugly inside a small hole and heat is transferred reliably and uniformly via the process of conduction. Industries that commonly use cartridge heaters include the medical industry, food manufacturing and production, packaging, and plastics moulding.
An alternating current is passed through the coil inside the cartridge heater — heating up the resistive wire. This heat energy is then transferred from the wire — first into the metal sheath and then the surrounding area — via the process of conduction. All heat energy is transferred from the element to the surroundings and, as a result, cartridge heaters are deemed the most efficient way to transfer heat into a metal solid.
Installing a cartridge heater incorrectly can lead to a wide range of issues, including the premature failure of your heating element. So be sure to take your time and get it right. Always take care when using heat transfer lubricants and protect the leads as much as possible. Detailed information regarding how to install a cartridge heater can be found in our online guide.
Get to grips with each step and, if you have any questions, feel free to give our experts a call. For example, you must select the ideal cartridge heater for your requirements. You need to consider the size, voltage and wattage very carefully. If the heating element does not fit snugly inside the hole, or the voltage rating or wattage is inappropriate for the application, heat will not be dissipated efficiently — leading to undue damage and the eventual breakdown of the element.
For example, high temperatures and excess movement can be problematic. These heaters are driven by AC current. When the current passes through the heater, the resistance coil gets heated and it transfers the heat energy to the metal sheath and then to the surrounding area.
This heat energy transfer is known as conduction. As the entire heat generated in the coil is transferred to the surroundings, it is known as one of the effective industrial heaters. Owing to their widespread use, today, it is easy to find them across different brands.
Although each brand has developed its specifics, these heaters have gained popularity owing to some of their general features:. These heaters are used to heat metal molds, platens, dies, and various metal parts in the metalworking industry.
Is that all? The following applications also make use of these cartridge heaters. As the working and benefits of cartridge heaters are well introduced here, you must source them from trusted manufacturers or suppliers. JavaScript seems to be disabled in your browser.

September 18, Electric Stud Heaters CBH Series heaters are constructed of rugged metal sheathed tubular elements homogeneously combined with a metal sleeve that has been accurately dimensioned to provide a proper clearance and ease of inserting into standard drill hole sizes so large bolts or studs may be rapidly expanded and tightened with a wrench, providing ''shrink fit tightness" when cool.
Useful in assembly of large compressors, presses, turbines, die blocks, cylinders, engine heads, pressure vessels, etc. Quick heat-up is important to avoid heat drain-away of surrounding metal. CBH heaters are generally used in sets to permit uniform tightening of mating parts.
Determining Watt Density The term "Watt density" refers to the heat flow rate or surface loading. It is the number of Watts per square inch of heated surface area. Use a watt density only as high as needed. Take advantage of the safety margin provided by using ratings less than the maximum allowed. Select space heaters for most even heat pattern rather than the highest possible wattage per heater. At medium Watt densities, general purpose drills are usually adequate for drilling holes.
Typically, these result in holes. Of course, the tightest fit is desirable from a heat transfer standpoint, but somewhat looser fits aid in installing and removing cartridge heaters, especially long ones. Holes drilled completely through the part are recommended to facilitate removal of the heater. After drilling, clean or degrease the part to remove cutting lubricants. At high Watt densities holes should be drilled and reamed, rather than just drilled to final diameter with a general purpose drill.
At high watt densities, a close fit is important. The fit is the difference between the minimum diameter of the heater and maximum diameter of the hole. Each industrial rod heater will come in a specific watt density. Leads and voltages also vary between models. The equipment is utilized in these commercial applications:.
We have high-watt or medium-watt density rod heaters available. First-class materials and manufacturing are featured in our durable rod heaters for commercial applications.
Our knowledgeable Hi-Watt team will help you locate the best industrial electric heaters for your needs, so call today. A rod heater is a heating element designed for industrial use.
The internal components are encased in a metal sheath made from stainless steel. The tubes contain a nickel-chromium heating coil wrapped in electrical insulation. They are made to fit tightly into holes created with standard drill bits. These heaters typically have a standard electrical cable.
Based on your needs, our skilled team at Hi-Watt can also create custom heaters designed with alternative electrical connections such as flange mounting, right-angle exit, fixing tab and more. Cartridge heaters come in a variety of sizes, wattages and ratings.
These heaters can create very high temperatures. They are the perfect heating element for high wattage industrial use. They are very versatile and are used in a wide variety of applications.
