The HTLe low-temperature self-limiting electric heating tape can be used for pipe freeze protection (including plastic and metal pipes) in residential and commercial applications, as well as for roof and gutter snow melting. Regardless of whether the pipes are overhead or buried, this model of product can maintain the temperature of the medium inside the pipes and preserve its phase. It can also effectively melt accumulated snow on residential or building roofs and in the gutter areas of large buildings, preventing potential safety hazards caused by snow turning into ice. In general, commonly used water pipes, fire sprinkler pipes, grease waste pipes, and similar pipelines can all use the HTLe low-temperature self-limiting electric heating tape for freeze protection and snow melting.
