Home | Pipe Heating | Technical Briefs | Components Components Controls When it comes to impedance systems, there are some design parameters which are dictated by the application. For example: Where do you put your isolation? How much power do you need to put into the pipe? Basic System Components The three basic system components of impedance pipe heating are isolation, power and control. Impedance Pipe Heating System Components In past issues, we have most often presented applications for impedance pipe heating and how it is being used throughout industry today. With this issue we step back and review the primary components of an impedance pipe heating (IPH) system.
