Know All About Different Types of Immersion Heaters

Different industries these days tend to use immersion heaters in tanks and containers to heat a liquid in the easiest way possible. In this article, there will be a comprehensive discussion on such heaters and how they are installed. 

An immersion heater can be defined as a particular device that is often installed in a particular container or a tank so that a particular form of liquid can be heated in the best way. The installation of an immersion heater can happen in a threaded, flanged, or over-the-side manner. Here we are going to talk about these three in detail.

Over-the-Side Heaters

These are the industrial heaters that are particularly designed for those vessels in which the side heaters are not conveniently installed. In the case of over-the-side heaters, they can be installed from the vessel’s top along with the heated section. It can also be installed in the bottom section as well. With the natural circulation of the liquid, even distribution is entirely possible. There are lead wires and terminal houses that are offered in order to have a proper distribution of power in the best way. These immersion heaters are extremely popular in the industry these days. 

Flanged Heaters

When we are talking about the flanged immersion heaters, it can be said that there are hairpin-like tubular elements that can be brazed or bent in order to create the shape of a flange. There are certain wiring boxes that are available in order to establish proper electrical connections as well. For installing the flanged heaters, special attention must be given to the process of bolting the heater into the flange that is welded properly into a nozzle or the tank wall. 

There are also different types of flange sizes that one needs to choose from. Apart from that, these heaters also tend to have sheath materials, kilowatt ratings, terminal housings, and voltages as well. Hence, these heaters are definitely suitable for creating different heating elements. 

Threaded Heaters

The third type of immersion heaters that we are going to talk about here are the threaded ones. Much like the name of the heaters, there are tubular elements that tend to be welded or brazed into the screw plug of the tank. There are different wiring boxes available in the heater for the function of creating electrical connections in the best way. 

These types of heaters are the ones that have a direct screwing method in use. If a tank has some sort of an opening that is threaded, then these heaters can easily be installed through those with the help of the instructions. When it comes to threaded immersion heaters, these tend to be really popular as well due to the inclusion of components such as sheath materials, kilowatt ratings, and much more. 


So, these are some details about the industrial heaters that you need to know about. We hope that this article was helpful in clearing all of the doubts that you might have about these types of heaters that are used in several industries.
