Induction Heater: All you need to know

Many industries use different methods of heating elements than most people are familiar with in their homes. One of the different types of heating these industries use is induction heating. Heating elements through this method requires an induction heater. While most people who work with these heaters don’t need to understand exactly how they work, this knowledge can be useful nonetheless.

What is an inductor heater and how does it works?
An induction heater is exactly what it claims to be. It is a heating unit that works but utilizing powerful magnetic fields to heat a conductive body. There are three main components to an induction heater, the primary part being the coil. The coil is actually composed of many smaller coils – copper coils – wrapped around and around each other, and a central mandrel (a rod whose purpose is to be coiled by other metals and to keep them in the desired shape). The coil is the inductive unit, transferring the heat through from the power source to the working surface.

The power unit is of course the generator, the item that all induction heaters depend on, its function is to take in the power from the mains supply, and increase it to an average anywhere between 2-500 kW. The final component of any induction heater is the working surface or work head. This is simply an area of capacitors and transformers whose job it is to link the power from the other two units and allow the heater to function correctly.

They usually work on one of two frequencies known in the business as RF and MF induction. The difference between the two is simply power. RF induction works between 100 kHz and 10 MHz, RF style heaters are used for smaller items and heating needs, while the MF Induction heater(s) work on a range anywhere between 1 kHz and 10 kHz and are, as a general rule of thumb used on larger components.

What are the Benefits of induction heater?
There are many reasons some industries use induction heating as a preferred method instead of other methods. One of the most common reasons is the danger of open flames. In some situations, especially when there are certain gases present, the use of an open flame can be extremely dangerous. Because induction heating doesn’t require a flame, it is often a safer alternative. It also often uses less energy and is effective at melting elements evenly.
Understanding the use of an induction heater can help you perform your job better. Even if learning how it works and why it is used doesn’t help you with your job, you can still benefit from this knowledge, especially if you need to explain the problem you are experiencing to a repair person.

Knowing how the heater works can also ensure you are using it properly so you can enjoy all the benefits this type of heating has to offer you and your industry. Having a tool like this that can offer you a safer work environment is a benefit as well. You can find an induction heater at
