Electric Heat Pipe Tracing Cable –-Self-regulating Heating Cable

ZWK series self regulating heating cable (Medium-temperature Max 105℃ )

Electric heat tracing cable increasing or decreasing heat output in a self regulating way depend on the ambient temperature change.Self regulating heat tracing cable consist of two parallel bus wires , embedded PTC semi-conductive self regulating matrix, so it is no need thermostat for self regulating heat tracing cable.it will never overheat or burnout even when wrapped by itself (overlapped).with optional outer jacket, the heat tracing cable is resistant to corrosion, watery, explosion and organic and inorganic chemical and protect from abrasion and impact damage. the maximum maintain temperature is ZWK series +105℃     


● Energy saving, self regulating,automatically vary its power output respond to pipe or vessel ambient temperature changes.l Cut to any length as you want (up to max circuit length),easy to install and pave along with pipe.

● Low install cost than another heat tracing, less maintenance charges and less downtime.

● No overheat or burnout even when overlapped.

● Several output powers

● Suitable for use in non-hazardous, hazardous and corrosive environment.


Electric self regulating heat tracing cable is designed for residential, commercial and industrial filed , mainly used for freeze protection or temperature maintenance of metal or plastic pipework and vessels, roof and gutter deicing applications. snow melting outdoor according to the filed that you need. also include some special fields, such as flue gas desulfurization (FGD) for electricity generating station, oil well, ocean ship and fire pipe.so it is ideal for using in freeze protection, temperature maintenance, keep the fluid flow and in right degree.in a word, meet process requirements
