So you’re in the market for an induction heating system? Induction heating is a fast, efficient heating process that requires a minimal footprint, so it’s a great choice for industrial heating. There are many options out there, so here are a couple key considerations to ensure you choose the right vendor for your company and application:
Any company can sell you a power supply, ship it to you, and wish you the best. A company that provides applications testing, uses their induction and applications expertise to prove out your process, and recommends the right system for your process requirements can make all the difference. If you need a part heated in 10 seconds, you might need one power supply, but if 20 seconds is sufficient a lower power solution might be all you need. Tailored applications expertise from an experienced team in a proper lab can save you money and headaches.
Designing and creating the right coil for your heating application is also critical. Be sure your vendor can recommend, design and supply a tailored coil that will maximize the efficiency of your process so you can take full advantage of the benefits of induction heating.
Does the vendor actually make the equipment, or do they merely resell it? Logically, if the facility that designs and manufactures the equipment is supporting you in process design, service and support after the sale, you’ll enjoy a better experience that leads to superior results and uptime. Is the vendor's facility ISO certified? Does the equipment have CE marking? If you are an OEM, do they have experience manufacturing for OEMs?
Cheaper isn't always better. Some imported units have a low power rating which leads to inferior efficiency – in effect less power is getting to your part. You might find one company’s lower power system can do the same thing another company’s higher power system does, so the price advantage evaporates. Also, be sure to check on the warranty.
Being able to easily change capacitors, tap transformers and coils will allow you to use your system for multiple applications if you so desire. Some systems even automatically update their taps based on the load.
Is your vendor focused on induction? For example, if you want temperature logging and monitoring, does your vendor have a solution? If you have a large part, can they offer a flexible coil that will work for you? If you’re focused in a unique application like nanoparticle heating, can a tailored solution be offered? Do they have temperature control and monitoring options?
Service and Support
Is the supplier you’re considering set up to support you? Do they stand behind their product and offer a two-year warranty? Can they come, set you up, and do training? Consider whether they actually make the equipment (and therefore really know the equipment), and if they have a team that can get to you efficiently.
Again, do they actually manufacture the equipment? Have they been around a while? Are their clients saying good things? Learning about the vendor’s reputation will give you invaluable peace of mind.
Cost of Ownership
What vendor/solution will ultimately lead to the best experience and the lowest cost of ownership? Some companies have had to replace all of their systems from their initial vendor because they under-delivered on power and support was minimal at best.
