Project Description

CABT++ low temperature self-regulating heating cable consist of a heating semiconductor plastic element which adapts its calorific power (W/m) on each point depending on the local temperature. This intrinsic feature of the semiconductor heating element allows in some cases to dispense of using a thermostatic controler (self-regulation).

They can be cut on the adjusted length directly on the job site. For your heat tracing installations and especially on temperature maintenance of hot water systems, we strongly recommend the combination of our electronic THA / E controllers.

The latter are equipped with a current absorber for start up of self regulating heating cables. They are the guarantee of a rigorous and reliable electronics regulation (energy saving of + 50%).



  • Freeze protection of hot watter pipes at 65C or 85C.
Thermal power output determined in compliance to standard EN 62.395.


  • can be cut directly on the adjusted length on the site

  • allow derivation from a unique and single feed point.

  • semiconductor heating element adapts its power locally.

  • good flexibility allowing the tracing of hydraulic organs (valves, pumps, …)

  • allow overlaps during implementation (self-regulating).

  • maxi temp energized : 85 Æ C (power on)- maxi temp de-energized : 125ÆC.

  • Technical CSTB approval, in accordance with the European standards in force.

The dissipated heating power of the self regulating heating cables CABT&CABT++ at each point of the cable varies according to the temperature of the contact point of diffusion where the cable is positionned.
Thermal power output determined by manufacturer in compliance to standard EN 62.395
