When it comes to impedance systems, not all systems are made equally. Yes, all impedance systems heat by passing current through a pipe. Yes, they all have a set temperature they can maintain. But what about the amount of time it takes the system to heat from startup? What about the ability to heat a product as it flows through a pipe? What can each system do? Or, as usually asked in the initial design phase, what does this system need to do? That simple question opens the door for many possibilities when it comes to the design of an impedance heating system.
