Welcome To Share This Page
Self regulating heat trace cable, which is also known as self limiting heat trace cable, heating cable, heat tracing cable, or heater cable.
- DBR is a low temperature self regulating heating cable for pipes ,tanks and vessels, which can be used for freeze protection or temperature maintenance in industrail field.
- DBR also can be used for deicing heat tracing cable, self regulating gutter heat cable and self regulating roof heat cable in residential field.
- It is normally suited to small diameter metal / non-metal pipes and roof & gutter tracing heat.
- It can be cut-to-length at site.
- DBR is approved for using in non-hazardous and hazardous areas.
- Its self regulating heating element (PTC: Positive Temperature Coefficiment) improve safety and reliability.
- DBR will not overheat or burnout, even when wrapped by itself.
- Its power output is self regulated in response to the pipe & ambient temperature.
- DBR can be manufactured by custom color and size.
- Please use approved termination, splicing and power connection components with DBR heat trace cable.
