Faster than a speeding bullet! More powerful than a locomotive! It’s not up in the sky, it’s…unbelievably efficient induction heat technology!
Ok, maybe I sound a little fanatical, but if you’ve never seen induction heaters in action, I seriously recommended you watch some induction heating demos. These videos will blow your mind. You’ll see metal wires melt, aluminum cans explode, and ice cubes set ablaze—before they even have a chance to melt!
What is induction heat?
Induction is a heating method, but unlike conduction or convection heating methods, it doesn’t require a transfer medium. The inductor itself can be a simple-looking strip of coiled metal (precisely designed to optimize the magnetic field and alternating currents), and the magic is, the inductor never touches what it’s heating, and it never gets too hot to handle with bare hands. I won’t get into the physics of it all, but if you’re interested in how induction heating works, see inductionatmostpheres.com. Basically, induction heat uses radio frequencies, and that’s how it can work sans transfer medium—heat is “induced” by the circulating electrical currents.
The shift toward lean manufacturing and the emphasis on better quality control have led to the rebirth of induction technology and the development of precisely controlled, solid-state induction power supplies.
How can induction heat benefit manufacturers?
For most industrial applications, induction heating offers significant advantages over traditional heating methods—the fast, accurate, and consistent heat transfer reduces energy consumption and creates a safer working environment.
Companies like Ford, John Deere, GM, Cat, Volkswagen, and BMW have already implemented induction heat into their manufacturing processes. Most manufacturers that switch over to induction technology report a decrease in their utility bills. Why is this? Because induction is a highly efficient means of heating that requires less energy to do the same job as, say, a heater band, which is constantly losing energy and reheating.
In fact, uninsulated heater bands are only 30-70% efficient and have a limited lifespan because they must stay hot to operate. Induction heaters, on the other hand, are typically 95% efficient and don’t emit excess energy. Even better, insulated induction heaters can reduce ambient energy loss by 98%.
How can you use induction heat to make your manufacturing process more efficient? If you haven’t already, start thinking about this innovative heating method, and stay tuned for the latest in energy efficient technology.
