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? Read the Article…

Maintenance and Your Impedance System
Most heating systems used today have some form of recommended maintenance schedule. Whether it is a complex series of steps that must be done at specific intervals, or simply occasional checking of certain parts, all maintenance schedules have the same basic purpose. Read the Article…

Temperature Maintenance vs. Temperature Rise
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. Read the Article...

How Does Impedance Pipe Heating Heat a Pipe?
While in essence the simplest and most elegant way to heat a pipeline, impedance heating technology is often viewed incorrectly and misunderstood as a method to heat pipe. At its core, impedance pipe heating is done by applying a low voltage AC source to a pipe and allowing electric current to pass through the pipe. While technically any voltage can be utilized, without special isolation and containment provisions the National Electric Code (NEC) limits impedance system designs to a maximum secondary voltage of 80V.

Applications

Advanced Flow Control Research Facility and IPH
Typically people consider using electric impedance pipe heating (IPH) for fluids and oftentimes that is their first application. However, electric impedance pipe heating is not limited to fluids — it can be used effectively to heat gas and vapor phase products as well.  Read the Article…

Impedance Pipe Heating and Conductive Fluids
Previous articles have focused on specific applications for impedance pipe heating. Now we would like to address a less conventional use: transporting an electrically conductive material.  Read the Article…

Application of Impedance Pipe Heating Systems
While impedance heating is an appropriate method to maintain and heat pipes, it is not always the best option. So how do you know when to consider and apply impedance pipe heating? Here are five areas where impedance heating is always an excellent choice:  Read the Article…

Impedance Heating System Application
Over the last several newsletters, we have addressed a variety of topics on many different aspects of an impedance system. We have seen how it works, examined the different components of a system, and looked at the maintenance requirements. Now, we will look at a practical application of an impedance system, and the benefits of impedance heating over other methods. Read the full article...

Application Challenges Solved
Impedance pipe heating. By now, those words probably conjure an image of a long delivery line: a stainless tubing line in a food plant, or a carbon steel line in a production facility. In either case, just a simple delivery line, taking product from a tank or storage area to a use point. Is this the only place to use impedance? Is it relegated to fixed delivery lines and nothing else? Of course not! While it is a simple and effective method of heating pipe, it can also be a flexible one. Read the Article…
