Immersion Heater Element Types

Immersion heater elements 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 make them a bit more robust than some of the other options.  This style of heater is often used in the 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 salt water. Some come with the flange already built in and some will need it welded on to 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 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 containers 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.

What is an Immersion Heater?

Immersion heaters are used in a variety of applications to keep chemicals, fluids, and gases warm.  They are installed on trucks as well as in large tanks to heat what is around them rapidly. The heating element of the immersion heater is submerged into the substance that it is heating.  There are different types of immersion heaters such as Circulations heaters, flange heaters, and over the side heaters as we discussed above. And, they are used in a wide variety of applications.

Immersion Heater Applications

Immersion heater applications are all around you.  These amazing heaters are used in the homes as well as businesses and industrial settings.  Pasteurizing milk, or heating up the oil are some of the more common applications. And, heating up water, yes, your water heater, if it is electric contains an Immersion heater.  They are used in the Nuclear Power industry, wastewater management, gas/oil industry, cement curing, food processing, laboratories, and the chemical industry.
