Why You Should Use a Cartridge Heater

A cartridge heater is a heavy-duty industrial Joule heating element that is used in the process heating industry. A cartridge is usually custom-made to meet a specific watt density and is intended for a particular application. These devices are used in a variety of industrial applications. This article discusses a few of the main reasons why you should use a cartridge heater in your application. Here are some of the most common types of heating elements.

A cartridge heater is susceptible to a number of potential contaminants. The sheath is usually made of stainless steel or Incoloy, allowing it to resist temperatures up to 1400degF. The electrical termination of the cartridge should also be temperature-rated. TGGT and Teflon lead materials are commonly used, and MGT wires can withstand temperatures up to 840degF. For higher temperature applications, a heater with separate zones is best.

A cartridge heater’s sheath is made from a conical copper rod filled with magnesium oxide. A copper core is added for insulation, and the NPT fittings are brazed on the lead end to provide a stronger connection. The sheath is made of various alloyed metals, including stainless steel 316 and Incoloy 800. It is important to consider the operating temperature of your cartridge heater when choosing its sheath.

A typical cartridge heater contains three different types of heating elements. The first type is a continuous-flow ceramic tube. It is commonly used for melting brittle objects. It can be controlled using a rotary encoder or an electrical controller. These heaters can have a temperature range up to 1200degF, which is ideal for the most common process demands. A rotary nozzle is a better choice for a single-chamber application.

The sheath is a metal element that comes into contact with the material being heated. It can be made of various metal alloys, but typically is made of nickel. Incoloy is an alloy that has the highest temperature rating. It is used in a wide variety of applications. Its sheath is made of 316 stainless steel. If you’re using a cartridge heater in a vacuum, you should choose an electric cylinder.

A cartridge heater can pass electrical tests, enabling it to pass with ease. It is often equipped with a thermocouple. Its main function is to regulate the air temperature of an appliance, but it can also be used in a vacuum cleaner. If it needs to heat water, then it will require an additional cooling device. If it needs to heat liquid, it can be connected to a gas line. You can then use a thermisat.

The length of the cartridge heater should match the length of the object to be heated. If the length of the item to be heated is shorter than the heater’s watt density, it may result in hot spots. The hottest cartridges have long-range heat distribution. However, they have more unheated portions. This is why it’s important to find one that has a standardized height. It can also be sized if needed.

The resistance wire in a cartridge heater is an electrical load. It comes in several types and the resistance wire used is the most common one. In order to prevent the heater from failing to work, the heater should be rated for a certain voltage. A nichrome coil is a good choice if you are a medical professional. This type of device should be compatible with all kinds of equipment. If you need a more powerful unit, you can also use an inductive power supply.

The resistance of a cartridge heater is determined by the amount of current that passes through it. This is because the heat is generated by the coil in an electrical circuit, and the resistance is directly proportional to the number of turns. The higher the watt density, the higher the resistance. If you need a more powerful cartridge, you need to use a higher-watt density unit. It will increase the resistance of the heat source, which in turn reduces the risk of failure.

A cartridge heater should be installed in a location that is free of electrical wires. It should be anchored securely in a place where there is no flexing. The lead wires should not be a problem if they are secured properly. The lead should be as short as possible to avoid vibration. It should be placed close to the working surface. This will allow for even heating throughout the part. If you’re not sure what kind of heat source to use, you can consult a manufacturer’s website.
