Selecting the right igbt induction heater can make a big difference in your work. You need to think about what material you want to heat, the size of your workpiece, and how deep or even you want the heat. > Canroon’s years of experience help you match the right heater to your needs, making your process more reliable and efficient.


Key Takeaways

  • Pick a heater that fits your workpiece material and size. Different metals need different ways to heat.

  • Think about how deep and even you want the heat. Choose a heater with a coil that heats evenly.

  • Make sure the heater’s power matches your biggest job. Good heaters use less energy and help you save money.

  • Look for safety features like automatic shutoff and over-temperature protection. These keep the heater safe to use.

  • Talk to experts like Canroon for advice and help. This can stop mistakes and make your heating better.


Application Needs

Workpiece Material and Size

When you choose an igbt induction heater, you need to look at the type of material you want to heat. Different metals react in unique ways to induction heating. Here are some examples:

  • Steel absorbs less heat because it has high resistivity.

  • Copper needs more heat to reach the right temperature since it has low resistivity.

  • Magnetic materials heat up quickly due to hysteresis.

  • Non-magnetic materials require more power to achieve the same results.

The size of your workpiece also matters. Small parts need less power, while large parts require a heater with a higher power rating. Canroon’s team helps you match the right heater to your material and size, so you get the best results.

You can see how power rating changes with workpiece size in the table below:

Heating Depth and Uniformity

You need to think about how deep you want the heat to go into your workpiece. Some jobs need surface heating, while others require heat to reach deeper layers. Uniform heating helps you avoid cracks and weak spots. If you want even heat, you should pick an igbt induction heater with the right coil design and frequency. Canroon’s experts can help you choose a system that gives you the best heating depth and uniformity for your project.

Tip: Always check if your heater can deliver the right depth and evenness for your material. This step helps you get strong and reliable results.

Process Goals

Your process goals shape your choice of igbt induction heater. You may want to harden, weld, or solder your workpiece. Each goal needs a different heating profile. If you want fast heating, you need a high-power heater. If you want gentle heating, you should pick a system with lower power and better control. Canroon’s experience helps you match your process goals with the right heater, so you get the results you want every time.

Power Output and Efficiency

You need to pick the right power for your job. Small parts need less power. Big or hard jobs need more power. The table below shows what power ranges work best:

Power Output Range

Application Suitability

2.5 kW - 100 kW

Good for many heating jobs in different industries

7.5 kW - 100 kW

Works well for many uses in factories

5 kW - 40 kW

Best for certain factory heating needs

Modern igbt induction heaters use less energy than old ones. They heat up faster and waste less power. You can see the differences in the table below:

Feature

Modern IGBT Induction Heaters

Older Technologies

Efficiency

Saves 30% to 50% more energy

Wastes more energy

Heating Method

Heats without touching

Needs to touch to heat

Heating Speed

Heats fast and with control

Heats slower

Energy Losses

Applications

Used in many industries

Used in fewer jobs

Tip: Pick a heater with enough power for your biggest job. Do not get one that is too big. High efficiency helps you save money and energy every day.

Frequency Selection

Frequency changes how deep and fast your heater works. Use lower frequency to heat the whole part. Use higher frequency for just the surface. The right frequency saves energy and gives better results. The tables below show how frequency changes your work:

Heating Requirement

Frequency Choice

Whole part heating

Lower frequency

Surface heating

Higher frequency

Frequency Type

Heating Application

Energy Efficiency

Lower Frequency

Good for deep heating of big parts

Saves more energy for deep heating

Higher Frequency

Good for surface heating of small parts

Not as good for deep heating

Heating Depth

Frequency Impact

Deep Heating

Use lower frequencies

Surface Heating

Use higher frequencies

Note: High frequency lets you heat small areas with control. Lower frequency is better for deep and even heating.

Coil Design

The coil is a very important part of your igbt induction heater. The coil’s shape and size must fit your part. A good coil gives even heat and saves energy. A bad coil can cause hot spots or uneven heat. Always check if the coil fits your part and job. Canroon can help you pick or design the right coil.

IGBT Voltage and Current Ratings

You need to check the voltage and current ratings of your igbt induction heater. These numbers show how much power the heater can safely use. If the ratings are too low, your heater may break or not work well. Always match the ratings to your power supply and part size. For example, a 100 kW heater may need up to 150A at 380V AC. See the table in the last section for more info.

Always use a heater with ratings that are right for your job. This keeps your system safe and working well.

Thermal Management

High-power igbt induction heaters get very hot inside. You need to control this heat to keep your heater safe. Here are some tips:

  • Make sure the bottom of the machine has good airflow.

  • Do not block the air coming in or out.

  • Check for dust or dirt that could stop air from moving.

If you do these things, your heater will last longer and work better.

Remember: Good thermal management stops overheating and keeps your heater working well.

Space and Layout

Plan your workspace before you put in an IGBT induction heater. The heater’s size and type decide how much space you need. Stationary heaters are big and stay in one place. Portable heaters are smaller and easy to move. Make sure there is enough room for the heater and workpieces. Leave space so people can walk around safely. A good layout helps you work faster and keeps you safe.

  • Think about what size and type of heater you need.

  • Stationary heaters need a set spot.

  • Portable heaters fit in small spaces and move easily.

Power Supply Compatibility

Check your power supply before you set up the heater. Most IGBT induction heaters need three-phase power. Match the heater’s voltage and frequency to your building’s power. This keeps your system safe and working right.

Tip: Always check if your power matches the heater. This stops damage and keeps things running.

Cooling and Ventilation

IGBT induction heaters get hot when you use them. You need good cooling and airflow to keep them working well. Water-cooled heaters are best for long jobs and high power. They heat fast and save energy. Air-cooled heaters do not need water. They work well for small jobs and are easy to use.

  • Water-cooled heaters keep things steady and stop parts from bending.

  • Air-cooled heaters are good for small jobs and simple setups.

Let air move around the heater. Clean dust and dirt from vents to help cooling.

Safety and Environment

Safety is important when you set up an induction heater. Keep the area clean and free of mess. Induction heaters do not touch the workpiece, so they last longer and need less fixing. They use less energy and save you money. Good safety keeps you and your equipment safe.

Note: A clean and safe place helps your heater last longer and keeps everyone safe.


Advanced Features

Automation Options

You can make your work faster with automation in IGBT induction heaters. Water-cooled high-frequency devices let you control temperature very well. These systems help heat your workpieces the same way each time. You finish jobs quicker and use less energy. The contactless heating keeps your equipment clean and stops it from wearing out fast. This method also lowers the chance of contamination. This is important for places like aerospace and automotive. Automation lets you set up your heater for jobs you do often. You save time and get the same results every time.

Tip: Automated controls help you reach the right temperature fast and keep your process steady.
