881-Series Impedance Heating System
Impedance systems heat a wide variety of gases, liquids and viscous materials which are stored, pumped and processed in many different industries and applications. Impedance heating can be used in three basic ways:
Cold Start
Heat is applied to increase fluidity of static, viscous materials so they can be pumped.
Typical materials include asphalt, molasses and heavy fuel oils.
Maintain Temperature or Pipe Tracing
Heat is applied to a liquid or gas flowing through a pipe to offset heat losses. Typical applications include freeze protection or maintaining the fluidity of viscous materials.
Temperature Rise
Heat is applied to a liquid or gas flowing through a pipe in order to raise its temperature between the inlet and outlet of the heated pipe. Typical applications include heating corrosive liquids or high temperature process air.
Benefits of Impedance Heating
- Low Voltage Operation -All systems operate at less than 30 Volts, many at 10 Volts or below. INDEECO systems meet or exceed the requirements of the National Electrical Code (Article 427), assuring safe operation.
- Uniform Heating -Because the entire pipe effectively acts as the heating element, heat is generated uniformly throughout its entire length and circumference without hot spots.
- Simplicity -The impedance method takes the complexity out of pipeline heating. A few basic components comprise the entire heating system. Installation is simple; it can be installed without disturbing most of the existing thermal insulation.
- Wide Temperature Range -INDEECO has pioneered the use of impedance heating for applications ranging from below freezing to 1600°F. It is often the only viable option for high temperature pipeline heating.
- Low Cost -Installation costs are kept to a minimum by the inherent simplicity of the system. Likewise, maintenance is virtually eliminated; many systems operate unattended. Energy costs are low because the required energy is concentrated in the pipe and efficiently heats the fluid or gas traveling through it.
- No Burnouts -When the pipe becomes the heating element, burnouts and failures associated with electrical resistance tapes and cables are eliminated.
