Impedance Pipe Heating
What is an
Impedance Pipe Heating system?
The Banner-Day Impedance Pipe Heating (IPH) system is designed to heat carbon steel,
galvanized, stainless steel, or exotic metal pipe to maintain the desired flow
of product or material through the piping system. This is accomplished by
several methods. It can take solid product inside the pipe and heat it to a
desired temperature, gradually increase temperature as it moves thru the pipe,
or maintain a constant temperature as the product is transported. The Banner-Day IPH system enables
companies to operate their pipe network intermittently or constantly.
The system utilizes low voltage
electricity to heat the piping system. Temperatures can be maintained from
ambient to 1400°F with tight tolerances by means of digital temperature
control.
How does Impedance Pipe Heating work?
A Banner-Day Impedance system uses a low AC voltage to
produce an electric current in the desired piping. The Banner-Day Transformer
is connected to the piping using a power cable connected to a high strength
cable lug. (NOTE: The entire line of pipe is isolated from ground)
The low voltage AC current flows from the first transformer
connection point (by the tank) through the pipe to the cable lug located at the
use point. The current bypasses the pump unit, which is isolated from the
current by the two Insulated Pipe Joints (IPJ) and the bypass cable. From the
cable lug at the use point, the current flows through the return power cable to
the Banner-Day Transformer which is grounded at the return connection to
produce the zero voltage reference of the system.
The Banner-Day control panel controls the input power to the
Banner-Day Transformer by sensing the product temperature with a sensor
directly connected to the piping, and maintains the pipe line at the desired
set point.

Description
System Types
There are two types
of Banner-Day Impedance Pipe Heating systems: End Feed and Center Feed.

The end feed system is the most common and is used with piping
systems that have several branches. Excellent for both low and
mid-range temperatures, an end feed system is easier to install than a
center feed system. |

The center
feed system is used for longer systems without branch lines, and is
best for mid-range and high temperature applications. It does not
require insulated pipe joints or flange gaskets. |
