Immersion Heating Element Types

Immersion heating element and the different types

Immersion heating element types come in a variety of types to meet the various needs.  There are basically Circulation heaters, flange heaters, screw plug heaters and over the side heaters.  Let’s take a look at these various immersion heater element types.

Circulation Heaters

Circulation heaters are submerged into a substance that heats the substance around it.  It is used to heat up oil or water and usually has a sheath around it to protect it from the substance that it is heating.  These are great for freeze protection, heating water, and other applications. There are a few ways that circulation heaters heat.  One is conduction, as the heated rod warms up the substance around the rod, it will start to heat the substance next to it as well.

Convection, as the circulation heater heats a substance the substance will expand and rise to the top.  This creates a current within the container that the circulation heaters are in. Radiance is another way circulation heaters can work.  This is where electrical waves are placed into the substance, this method does not work with gases.

Flange Heaters

The heating element of Flange heaters is a bit of a blend of various compounds which makes them a bit more robust than some of the other options.  This style of heater is often used in petroleum, chemical, or water-based applications. Because they are made up of so many different metals they do resist corrosion quite nicely.  And, they are used in a variety of applications such as wax, soap, food applications, and saltwater. Some come with the flange already built-in and some will need it welded onto the flange that is already mounted.  These are the most widely used in the oil sector market.

Screw Plug Heaters

Screw plug heaters are heaters that have threads on them and can be screwed into their applications.  These are easy to replace type heaters that are used in a variety of applications such as food and beverage applications.  And, they are found in laboratory clinics, used with automotive oils as well as explosive gases.

Over the Side Immersion heating element Heaters

Over the side, heaters are popular in the industrial market.  They are simple to use as they literally just as their name suggests, hang over the side.  They have water-resistant housing and come in a variety of shapes and sizes to meet your container’s needs.  This style of heater is great as it is mobile and can be used in multiple containers if need be. And, they are simple to move from one container to the next.  They are used a lot with oil and as degreasing solutions. They will heat the substance around them gradually.
