Self-regulating trace heaters

Short Description:

Self limiting / self regulating heating tape adjusts heat output to equal the heat loss from the pipe work. As pipe temperature falls the electrical conductivity of the semi-conductive core increases causing the tape to increase heat output.

The WNH trace heater is used for freeze prevention and temperature maintenance on vessels, pipes, valves, etc. It may be immersed in fluids. For use in aggressive en[1]vironments (e.g. in chemical or petrochemical industry), the trace heater is coated with a special chemically resistant outer jacket (fluoropolymer).


1.Are you factory?
Yes, we are factory, all customers are more than welcome to visit our factory .

2.What are the available product certifications?
We have certifications such as: ATEX, CE, CNEX. IS014001, OHSAS18001,SIRA, DCI. Etc

3.How does self regulating trace heating work?

Self regulating systems work by:

Attaching the heating cable in a straight line underneath the insulation on the pipe.
Applying heating power in relation to the ambient temperature to maintain a holding temperature above freezing.

4.Does self regulating heat trace need a controller?
Although it's called "self-regulating," the cable will not turn itself completely on or off. So, we do recommend that a controller or thermostat of some sort to be used with this type of heating wire.

5.Can heat trace touch itself?
Constant wattage heat trace and MI cable cannot cross or touch itself. ... Self-regulating heat trace cables, however, would adjust to this temperature increase, making them safe to cross or overlap. As with any electrical system, though, there are always potential dangers with using heat trace or heat cables.
