Process heaters can usually be powered in different ways but the most commonly used ones is the electric version. Depending on your specific application, these machines can be utilized either for direct or indirect heating, making them a flexible heating solution. However, as it also comes in different variations, it is important that you pick the right one. Here is a quick overview of how each type works and for what uses.
Types of Process Heaters
Circulation Process Heaters
This type of a process heater works by heating the fluid as it goes through the enclosed system directly over the heating element. The device usually comes as a pipe or a tube through which the medium flows. Since this heater is highly specialized, it is often made customized to suit the unique requirements of its application.
A variation of indirect process heaters is the thermal fluid heating system. It works by indirectly heating the medium, transferring the heat and circulating it to heat energy users within a closed loop system. The most commonly used mediums of this system include water, oil and glycol.
Immersion Process Heaters
Unlike its circulation counterpart, immersion heaters heat the medium that passes through it directly. There are tubular electric elements that are being immersed in the process fluid, hence the name. The key benefit of using this heater is that it converts electricity into heat nearly one hundred percent efficiency. The heating elements are made of high quality materials to make sure that the results are optimum and the heater’s life is prolonged.
Finally, in terms of their applications, process heaters are used across industries for various uses. They are used to melt materials to create resins as well as to initiate chemical reactions during one of the operations. The list of its uses goes very long.
