Thermo De Icing Tracer

Thermo De Icing Tracer (TDIT-SR) is designed for various Domestic and Commercial De Icing application like Freeze protection of pipelines, vessel, and Snow and ice prevention on roofs, Gutters, Downspouts and so on.

Operating Principle

Thermo De-icing Tracer (TDIT-SR) consists of a self-regulating parallel circuit of a semi-conductive heating core extruded over plated copper bus wires. Modified Polyolefin insulation over semi-conductive heating core provides electrical insulation, over which a metal braiding or Aluminum tape with earth drain wire metal sheathing for earthing. An outer sheath of Modified Polyolefin makes the heating cable robust, water proof and UV protected.

TDIT-SR derives its self-regulating characteristic from the inherent properties of the semi conductive core material. With increase and decrease in cable core material temperature, conductive paths decrease and increase resulting in heat output decreasing or increasing. This occurs at every point along the cable’s length, adjusting the power output to the varying conditions. As the cable self-regulates its heat output, it limits the maximum sheath temperature, thus making it burn-out proof.
