The SelfTec DW is a self-regulating heating cable that proves itself as an advanced frost protection system. It can be used inside and outside the water pipe (the Selftec DW cable is approved for contact with drinking water). For outdoor installations, thermal insulation is required. When heating the pipeline with a heating cable, it is recommended to use the controller with a temperature sensor mounted on the surface of the pipeline. Due to their structure, heating cables can cross or touch and are not subject to local overheating.
